Motor Control Centers
The General Electric Spectra Series™ and 8000-Line motor control centers provide an economical means of centralizing motor starters and related control equipment. It permits combination motor control units, feeder tap units, distribution transformers, lighting panels, interlocking relays, programmable control, metering and other miscellaneous devices to be contained in a single floor-mounted structural assembly fed from a common enclosed main bus.
GE motor control centers are constructed of standardized heavy gauge vertical sections housing vertical and horizontal buses, wiring channels and compartmented control units.
Shipping splits are bolted together to form a single line-up assembly. Units are mounted and wired in accordance with the level of factory wiring purchased. The entire center may be powered by incoming line connection at a single point. Where possible, motor control centers bear UL section and unit labels.
The purpose of this publication is to simplify the selection of
GE motor control centers. The following logic flow chart lists basic items which must be considered for each application.

STANDARD DESIGN FEATURES
Design flexibility, performance, personnel and equipment protection, ease of maintenance and installation are all contained in the Spectra Series™. Spectra Series™ features, such as separate wiring troughs, split-type terminal boards, isolated bus, drawout starter units, operating mechanisms, and provisions for starter interchangeability, are designed for a high level of reliability and convenience.
These steel-enclosed control centers can be joined together to centralize and protect the most complex systems of industrial auxiliary drives, or the simplest of fan- or pump-motor controls.
As the need arises, additional sections can be added to an existing lineup.
General
Barriers located in front of the main horizontal bus isolate the bus from the top horizontal wireway. Maintenance personnel can easily gain entrance to the top horizontal wireway of the control center without danger of contact with a live bus.
Barriers furnished with 2-inch main bus systems use a sliding panel. After de-energizing the bus, maintenance personnel may slide back the panels to give ready access to the main bus for inspection of bolted connections. Main bus splicing is accomplished in this area with the hardware already in place. 4-inch main bus systems have stationary removable barriers
An incoming-line terminal compartment can be located at the top or bottom of a vertical section to allow cable termination with minimum bending. The standard 600-ampere incoming line terminal compartment shown is furnished with 2 mechanical type lugs per phase. Other incoming line terminal compartments are available for main bus ampacities up to 2500 amperes.

CODES AND STANDARDS
Motor control centers are manufactured to NEMA standard ICS
2-322 and are eligible to receive the Underwriters Laboratories listing mark under standard UL 845. Vertical sections and units which have been listed with UL will bear the listing mark. Since vertical sections and units are listed independently, it is possible to have combinations of listed and non-listed sections and units within the same control center. Sections and units which will be shipped with the UL listing mark are identified in the appropriate sections of this publication.
The National Electrical code covers installation of electric conductors and equipment for installations identified in the NEC Article
90. The NEC is not intended as a design specification and acceptance of an installed motor control center by a local code authority is dependent on factors independent of the equipment as shipped from the factory. In general, equipment which bears the UL listing mark can be installed to meet the NEC. Where 100 percent UL listed equipment is mandatory or there are other special code requirements refer to the factory for verification.
The NEC defines several types of control circuits and the overcurrent protection required for each type. The following paragraphs provide a general reference to the NEC Article applicable for the more common control circuits.
NEC Articles 430-72(a) and (b) cover motor control circuits tapped from the load side of a motor branch-circuit short-circuit protective device (unit disconnect). Control circuit conductors from such a tapped control circuit shall be protected in accordance with
NEC Table 430-72(b), which lists the maximum fuse or circuit breaker rating vs. conductor size.
Motor control circuits other than such tapped control circuits
(common control transformers or external power source) shall be protected against overcurrent in accordance with Section 725-12 or
725-35, as applicable, for the type power source and field wiring conductor sizes.
Where a motor control circuit transformer is provided, the transformer should be protected in accordance with NEC Article 430-
72(c). Transformers other than motor control circuit transformers should be protected in accordance with NEC Article 450-3(b).

SHORT CIRCUIT CONSIDERATIONS
ALL RATINGS IN THIS PUBLICATION ARE RMS SYMMETRICAL AMPERES
SHORT-CIRCUIT CURRENT RATINGS
The NEMA Motor Control Center Standard ICS-2-322 defines the short-circuit rating of a motor control center as follows:
“The motor control center short-circuit rating shall be the maximum available rms symmetrical current in amperes permissible at its line terminals. It shall be computed as the sum of the short-circuit current contributions of the motors connected to the motor control center and the maximum available current, including all other short-circuit current contributions of the supply system at the point of connection to the motor control center.”
MOTOR CONTROL CENTER BUS
Fig. 1
Figure 1 illustrates simply the basis of determining the available short-circuit current. The individual short-circuit current ratings of the main bus extensions, combination-controller units, and feedertap units must equal of exceed available short-circuit current.
Is is the short-circuit current available from the system at the point where the motor control center is connected. Im is the shortcircuit current contribution of the motors connected to the motor control center. If exact information is lacking, the motor contribution can be estimated at four times (4X) the continuous-current rating of the main horizontal bus. Isc is the available short-circuit current to be used as the basis for selection. Thus: Isc = Is + Im.
High available short-circuit currents of modern distribution systems require special consideration so that equipment may be operated within its rating. The cost and operational acceptability of the following should be carefully considered:
1. Use load-center distribution systems with smaller transformers which limit the available short-circuit current.
2. Use a current-limiting busway, reactors, or higher-impedance transformers to reduce the available short-circuit current.
3. Use current-limiting fuses, current-limiting breakers, or breakers with limiters, in all combination starters and feeders in the control centers.
lower in magnitude than the available short-circuit current and must be assumed not to be self-extinguishing. Even low-level arching faults are capable of releasing tremendous energy at the point of fault and can be highly destructive.
A NON-AUTOMATIC CIRCUIT BREAKER (MOLDED CASE
SWITCH) OR A NON-FUSED SWITCH MUST BE PROPERLY
COORDINATED WITH UP STREAM PROTECTIVE DEVICES.
For full protection against all levels of arcing faults on grounded systems, a ground-fault relay is recommended. The ground-fault system is a protective means that responds to phase-to-ground current, but is not affected by phase-to-phase current. It is used to protect motor control centers from extensive damage, which can be caused by phase-to-ground arcing faults.
Fuses are single-pole interrupters. An arcing fault may not necessarily be cleared by a single-pole interruption, as the fault can be back-fed from the other energized phases. This reduces the fault current, increasing the blowing time of the energized fuses.
Because of this delay, severe equipment damage may occur.
Single-phasing is eliminated with fast-acting three-pole fused interrupter switches which open when a single fuse blows.
An electrically operated HPC switch with single-phase detector will meet the three-phase disconnection (single-phase protection) recommendations for a main protective device.
When switches without a three-phase trip are used, a GSR ground-fault protection scheme is particularly recommended since damaging arcing faults almost always involve ground. It should operate the trip device on the closest line-side three-phase disconnect.
MAIN HORIZONTAL BUS AND VERTICAL
BUS EXTENSIONS
The standard bus short-circuit withstand rating is 42,000 rms symmetrical amperes. Also available optionally are ratings of
50,000, 65,000 and 100,000 rms symmetrical amperes. The bus rating must equal or exceed the available short-circuit current.
Refer to Structure (Section B) for ratings.
COMBINATION MOTOR CONTROL UNITS
The short-circuit rating of a combination controller is based on tests with rated short-circuit current available at the line terminal of the control center and at rated voltage.
The short-circuit rating must equal or exceed the available short-circuit current. Refer to Starters (Section D) for ratings.
MAIN PROTECTIVE DEVICES
A motor control center requires adequate overcurrent and shortcircuit protection. This is the function of the main protective device.
It may be located in or remote from the control center. Wherever located, it must have an interrupting rating equal to greater than the available short-circuit current at the point of its connection to the system. If located at the control center, this value would be the system available short-circuit current, Is (Fig. 1).
A motor control center should be protected for all types of faults from low-level arcing ground faults to bolted three-phase faults which can develop the full available short-circuit current. Line-toline and line-to-ground arcing faults (often produced by contaminated atmospheres, foreign materials, etc.) can be appreciably
FEEDER TAP UNITS
All feeder tap units must have a short-circuit rating which equals or exceeds the available short-circuit current. Refer to Feeders
(Section C) for ratings.

Spectra Series™ and 8000-Line
Motor Control Centers General
FUSE CLASSIFICATION
UL classifications are the most definitive method of determining fuse charactertistics, and are used in this publication. Use UL fuse
“Class” when specifying type of fuse.
UL classifications used in motor control centers are:
A. Class H—defines dimensions for 600 amperes maximum,
250 volts or 600 volts, with non-reject type mounting. Fuse characteristics may vary.
B. Class K—have Class H mounting dimensions and limit peak let-through currents, though not classified as
“Current Limiting.” Class K fuses are sub-divided into
Classes K-1, K-5 and K-9, depending on peak let-through current, with K-1 having the lowest peak let-through currents. K-9 fuses are not recommended because their peak let-through currents are too great to be considered safe for controllers. Class K fuses are rated 600 amperes maximum, 250 volts or 600 volts.
C. Class R—current-limiting type fuses with reject mounting features. Class R fuses are sub-divided into Classes RK-1 and RK-5, depending on maximum peak let-through currents. RK fuses are rated 600 amperes maximum and 250 volts or 600 volts.
FUSE CLASSIFICATIONS
D. Class J — are more current limiting than RKs and due to their unique dimensions have an inherent rejection feature. Ratings are 600 amperes maximum, 600 volts.
E. Class L — are current limiting and due to their unique mounting dimensions have an inherent rejection feature.
Ratings are 601 amperes minimum, 600 volts.
Fuses marked with “D,” “Time-Delay,” “Dual-Element” or similar designations are time-delay type fuses and will generally carry 500 percent rated amperes for 10 seconds, thus allowing a smaller rated fuse to be used in most starter applications.
UL listed combination motor starter units furnished with nonrejection Class H, K-1 or K-5 fuses are short-circuit rated 5kA for
NEMA size 1, 2 and 3 starters, and 10kA for larger starters. Higher short-circuit ratings require rejection type fuses. See Fuse
Classifications table below for short-circuit ratings.
Fuses that are mechanically interchangeable may not be electrically equivalent. Refer to the fuse manufacturer for interrupting rating and current-limiting characteristics.

ENVIRONMENTAL CONSIDERATIONS
The standard 8000-Line motor control center is designed for operation in a clean, indoor environment having a 40°C maximum ambient temperature.
The nominal minimum temperature for storage is -40°C and for operation, -20°C. Motor control center space heaters are recommended whenever temperature conditions below 0°C will exist.
Where extreme cold temperatures are to be encountered for long periods of time. It is recommended that the motor control center be installed in heated rooms or enclosures.
For ambient temperatures above 40°C, special consideration must be given to the need for ventilation, ambient-compensated breakers and overload relays, special wire insulation, and oversized control transformers. Ambient compensated overloads provide essentially constant trip setting as the control ambient varies.
For indoor environments subject to falling liquids, NEMA 2 dripproof enclosures are recommended. If water spray and splashing are to be encountered, NEMA 2 construction should also be used.
Space heaters may be desirable to prevent condensation on internal parts.
For outdoor installations, NEMA 3R weatherproof enclosures are required. These can be non-walk-in, walk-in, non-walk-in back-toback, and walk-through with common aisle. Thermostatically controlled space heaters and ambient-compensated breakers and overload relays should be considered for these applications.
Provisions for heating and cooling the entire outdoor enclosure are also available. Standard NEMA 3R construction is suitable for wind velocities up to 75 mph. Beyond this, up to 130 mph, specially reinforced enclosures are available. This special design is also necessary if the NEMA 3R enclosure has to withstand seismic conditions, including seismic Zone 4 applications.
A modification of the 20- and 22-inch deep 8000-Line motor control center is available for earthquake conditions. It can satisfactorily withstand a force of 5 g’s, 1 to 100 Hz, input at its floor sills simultaneously in all three orthogonal axes, and is suitable for
Seismic Zone 4 installation.
For dusty atmospheres, semi-dust-tight NEMA 1 gasketed or
NEMA 12 construction are recommended.
The altitude limit for the standard electro-mechanical motor control center design is 6000 feet. Applications above this should be referred to the Company for recommendations. Some solid-state components are only rated to 3300 feet and may reduce the altitude limit of the motor control center.
Fungus-Proofing of organic materials in a motor control center can be provided. It should be noted that the best available treatment has a very limited effective life of only a few months. Keeping equipment dry and above the dew-point is a much better way of avoiding fungus-growth, and the use of space heaters is recommended for this purpose. Heaters should be energized if the motor control center is to be stored for any length of time. Where export crating is involved, terminals for connection of an external source of space heater power can be provided on the outside of the crate.

Motor Control Centers Structure
OPTIONS
Space Heaters
Space heaters are used to prevent moisture condensation on the inside of the motor control center. One heater (62.5 watts at
120 volts AC) is installed in the bottom of each vertical section.
UL requires space heaters be controlled by a thermostat. One thermostat can control up to 14 heaters and is located in the top horizontal wireway.
A terminal board for connecting an external 120-volt power source is standard. The terminal board is located in the top horizontal wireway adjacent to the thermostat(s). This is recommended since it permits the space heaters to be energized and effective even when the motor control center itself is deenergized. If export crating is involved, the space heater circuit can be wired to an external plug for energizing the heaters during shipment and storage.
When specified, space heater power can be provided from within the motor control center. Include the required distribution transformer with primary and secondary protection in the motor control center.
An enclosed foreign voltage disconnect switch is available as an option.
Extended Height Pull Box (Top Hat)
A pull box can be mounted on top of a vertical section when specified. The standard height is 12 inches; 6-, 18-, and 24-inch heights are also available. Top, front, and end covers are removable for access.
Rodent Barriers
Metal plates bolted to the bottom of each end section to close the opening between the front and rear floor sills. Not required if the floor sills will be removed or imbedded in concrete.

Motor Control Center Construction
Bottom Plates
Plates bolt on to the bottom of each motor control center section. They may be removed to facilitate installing conduit.
Starters Mounted Back-to-Back (Single Section)
This construction requires a minimum 20-inch deep enclosure. A common main horizontal bus is furnished with individual front and rear vertical buses to maintain same phase sequence, front and rear. This allows for mounting draw-out units in the rear of the section without changing phasing.
The back-to-back section is UL labelled per table below and can be mounted in a NEMA 3R non-walk-in outdoor enclosure.
Care must be exercised when arranging units as some of the larger starters, power transformers, etc., require the full enclosure depth.

BUS SELECTION
All continuous–current rating selections or recommendations are based on the motor control center being located in a maximum 40° C (104°F) ambient. Refer to General (Section A) for other environmental considerations.
MAIN HORIZONTAL BUS
The size of motor control center main bus and cables feeding the main bus is based on the current-carrying capacity required for motors plus other connected loads.
The capacity required for motors can be taken as 125 percent of the full-load rating of the largest motor plus 100 percent of the full-load rating of all other motors to be operated at the same time. Modified requirements resulting from duty-cycle or demand factor can be taken into account.
The current-carrying capacity required for other connected loads should be computed on the basis of 100 percent of the sum of individual loads except where a demand factor can properly be applied to reduce this total. Consideration should be given to future requirements.
VERTICAL BUS EXTENSIONS
The maximum vertical bus loading is calculated as follows: 80 percent of the feeder trip or fuse clip rating, plus 100 percent of the starter full load amps, plus 25 percent of the largest motor full load amps. This total cannot exceed the vertical bus rating.
Tin plated copper verticval bus is standard, with silver plating as an option.
NEUTRAL BUS
Neutral bus is normally rated 50 percent or 100 percent of the main bus ampacity depending on system requirements.
GROUND BUS
UL requires a ground bus in multisection motor control centers. 300 ampere Cu or 375 ampere Al ground bus will meet minimum size requirements for main busses rated through 2000 amperes. A clearance hole for
3
/
8
-inch hardware is provided in each section.
OPTIONS
The following UL listed options are available:
• Cap plugs for unused vertical bus stab openings.
• Shutter mechanism for vertical bus stab openings.
• Fully-insulated main horizontal bus.
• Silver plated horizontal and vertical bus.
• Plated ground bus (tin/silver).

MAINS
GENERAL
Main units consist of an externally operable circuit disconnect, either a fusible switch or a circuit breaker. Sizes by ampere rating, short-circuit rating, type construction, and space units required are given in the accompanying lists.
Normally, thermal magnetic circuit breakers or fuses are necessary for main protection. The short-circuit interrupting rating depends on the type disconnect furnished. Select a main unit for which the interrupting rating equals or exceeds the maximum available fault current.
For reverse–fed circuit breakers, refer to factory for details.
Refer to specific breaker publications for time-current characteristics and programmable options for the various types of circuit breakers. A list of these publications is given in Application Data
(Section J).
SERVICE ENTRANCE
UL Listed main units containing only circuit breakers or fused switches may be UL classified as suitable for service entrance. If a single disconnect is furnished as a disconnect for all load circuits the unit will be marked “Main.”
In order for the units to be classified as suitable for service entrance, the incoming phase conductors must connect directly to the disconnect device line terminals or to a UL listed main line terminal assembly.
A grounding electrode conductor terminal connector sized in accordance with the circuit ampacity is furnished in one section.
Three-phase, four-wire systems include a neutral bonding jumper for grounding the neutral conductor during installation. Ground fault protection is required for disconnects 1000A and above for solidly grounded wye services, where phase-to-ground is more than 150 volts (NEC 230-95).
Refer to the factory when ground fault protection or metering is required.
MAIN METERING/LUGS
Line side CTs can be provided in the main compartment for use with a metering unit. This option will add space.
If crimp type lugs are required, a bus assembly is fabricated to provide a landing pad for these terminals. This extends the space required for the main and must be factory installed.

FEEDERS
Feeder units consist of an externally operable circuit disconnect, either a fusible switch or a circuit breaker. Thermal magnetic circuit breakers are required unless the feeder supplies a critical circuit, such as a fire pump controller.
Select the fuse or circuit breaker trip rating based on the feeder circuit continuous current rating in accordance with the NEC.
Feeder unit short-circuit interruption ratings must equal or exceed the available short-circuit currents.
Note that magnetic only circuit breakers are not approved for use as feeder units.

KEY INTERLOCKING
Provisions for key interlocking can be provided on all circuit breaks and fusible switches. The standard key lock is by
Superior Lock Corporation. However, coordination with Kirk key locking will be supplied if necessary. The following information is required when lock coordination is to be provided with other upstream or down-stream devices remote from the motor control center:
PURCHASED BY ________________________________
ULTIMATE USER ________________________________
DESTINATION __________________________________
LOCK MANUFACTURER _________________________
LOCK NUMBER_________________________________
PURCHASE ORDER NUMBER ____________________
Note:
•
Minimum 12-inch high units are required for key interlocking. UL listed option.
GROUND FAULT PROTECTION
Two types of UL listed ground fault protection can be provided as an option with feeder and main circuit breakers. A shunt trip device is required in the circuit breaker to trip the breaker if a ground fault should occur. Type TGSR ground break protective relaying is recommended for main breaker application. Model
#252 ground fault relaying is recommended for most feeder applications. See Components (Section H) for description of both ground fault relay types. A minimum of 12-inch additional space height is required in addition to the standard space height shown for each main feeder unit.
A separate 120-volt source for the shunt trip circuit will decrease the additional space required.
INCOMING LINE TERMINATIONS
The following cable terminal compartments are commonly specified for use in motor control center construction where the main AC power disconnect is located upstream of the motor control center.
For other custom cable termination arrangements refer to
Company. The number of cables indicated must be installed to maintain the short-circuit rating.

Motor Control Centers Starters
GENERAL
Combination motor control starter units consist of an externally operable circuit disconnect, either a fusible switch or circuit breaker, and a magnetic starter with an overload relay in the motor lines.
Unit NEMA sizes listed are based on continuous horsepower ratings. The maximum horsepower rating of each NEMA size controller is reduced for long accelerating times and for jogging or plugging duty. Jogging duty is defined as 5 or more contactor openings or closings per minute or over 10 in a 10-minute period.
Plugging is rapidly stopping or reversing the motor by reversing the phase sequence of the power supplied to the motor. Refer to the factory anytime accelerating times exceed 10 seconds or jogging or plugging duty is required.
The short-circuit interrupting rating depends on the type disconnect furnished. Select a starter combination for which the interrupting rating equals or exceeds the maximum available fault current.
Basic combination motor starter units consist of:
1. Externally operable circuit disconnect.
2. Magnetic starter with a thermal-magnetic, or electronic overload relay.
3. External overload reset operator.
4. Tapped line voltage, 120-volt CPT control power or external control power.
5. Drawout or pull-apart control terminal boards through NEMA
Size 4.
6. Drawout power terminal boards through NEMA Size 3 (when specified).
7. Extra CPT capacity for operating auxiliary relays and pilot devices (when specified).
8. Plug-in construction through NEMA Size 4 (FVNR) starters.
Bolt-in construction may require vertical bus modifications.
Specify basic starter units from the tables in this section.
Starters are listed by starter function, line voltage, HP, NEMA size, and combination short-circuit rating. Indicate type control power desired. Include any options from “Optional Modifications,” noting additional space requirements for some options.
Typical starter circuits are shown in Typical Circuits (Section K).
Starters can also be used for lighting or resistive heat loads
(Section J).

Motor Control Centers Starters
PRODUCT INFORMATION
UNDERVOLTAGE PROTECTION
Standard starters drop out when line voltage drops below approximately 65 percent rated volts and can be reclosed when voltage returns to 85 percent rated volts.
Where momentary contact devices are used in standard three-wire control circuits, the starter will not reclose on momentary loss of voltage until the START button is pushed, thus inherently providing undervoltage protection.
If a maintained contact device, such as a float switch, is used to start the motor, the starter will close automatically upon restoration of control voltage. In some cases, this may not be desirable for safety reasons, and a reset pushbutton and auxiliary relay should be specified to provide undervoltage protection.
LONG CONTROL CIRCUITS
On exceedingly long control circuits two problems may occur– (1) starter will not close due to line voltage drop and (2) starter may not open due to capacitive coupling. Table below gives the one-way distances (in feet) from the starter to the pushbutton along the route of the control cable. This table is for
120-volt coils and allows for a maximum voltage variation of 10 percent. The distances are given for #14 and #12 AWG control wire.

➀ Distance based on using an interposing relay, type MCR4, CR7A
[CR120B is 1600/2500 feet]
OVERLOAD RELAYS
Standard relays are three-leg block bimetallic type with adjustment from 90 to 110 percent of the heater rating. A single calibration adjusts all three legs. A single reset button mounted on the starter door permits external reset. Ambient-compensated relays are available for ambients from –30°C to +80°C and have adjustment from 90 to 110 percent of normal rating. Improved protection is provided when the motor is in a relatively constant ambient but control is subject to varying ambient. Relays are interchangeable with standard type.
SEPARATE SOURCE CONTROL CIRCUITS
A separate control bus is available as an option. This bus can be fed from a separate external source, or from within the motor control center by a separate distribution transformer or distribution panel.
A normally open auxiliary contact should be specified on each unit disconnect to open the control bus circuit when the unit disconnect is opened. Unit control circuit fusing should also be added.
In lieu of the auxiliary disconnect contact, pull-apart terminal boards may be specified to provide control voltage isolation for individual starters.
OPTIONAL ELECTRONIC OVERLOAD
RELAY
Both analog and digital relays are also available with or without communications (see page H-11).
CONTROL CIRCUIT PROTECTION
Motor control circuits tapped from the load side of the starter unit disconnect, such as line-to-line control and line-to-neutral control are protected by fuses in each ungrounded conductor.
UL requires rejection type fuses for equipment rated above 10KA short-circuit rating. 10 ampere, 600-volt Class CC fuses are furnished as standard. If loading dictates a larger fuse, the fuse rating may be increased up to 20 amperes maximum. Time delay
Class J fuses are available as an option.
Motor control circuit transformers are protected with a fuse in each ungrounded secondary conductor. Secondary fuses are
(Class RK-5) sized on the basis of 125 percent rated secondary
(20 amperes maximum). UL requires primary transformer protection in accordance with NEC Article 430-72(c). ATM-R fuses are furnished in each ungrounded primary conductor.
Motor control circuit power, other than power tapped from the load side of the starter unit disconnect, should be protected against overcurrent. The protective device may be located at the source or by the optional fuse(s) located in each unit. Normally, one (Class CC) fuse in the ungrounded conductor will provide the needed protection.
Where wiring external to the motor control center is indicated,
No. 14 AWG copper will be assumed as the minimum conductor size unless otherwise specified.
PILOT DEVICES
Pushbuttons, selector switches, pilot lights, etc., are singleunit, heavy-duty oil-tight type mounted on the starter unit door.

Power is tapped from the load side of the starter unit disconnect and the transformer provides 120-volt power. Two 600-volt primary fuses, plus one 250-volt secondary fuse in the ungrounded conductor is standard.
Standard control power transformer ratings are adequate to handle the starter-coil current and three pilot lights. If additional burdens are expected, larger transformers should be specified.

OPERATOR AND METERING PANELS
Unit spaces can be used to provide metering and/or operator’s panels in the motor control center itself. Arrangement and dimensions will vary depending on the quantity and type of the devices required. Normally, fuse blocks, terminal blocks, current and potential transformers, etc., can be mounted on a base within the unit space. Meters, pilot lights, pushbuttons, switches, etc., can be mounted on the door. Suitable locations and adequate space should be provided so that wiring is simplified and there is no interference between door and base mounted components. The following devices are often specified.
• Pushbuttons, selector switches, pilot lights.
• Ammeters, voltmeters, and other instruments (panel or switchboard type).
• Instrument and transfer switches
• Electronic power meter
• Control relays
• Timing relays (pneumatic, motor-operated, or electronic)
These panels will be UL Labeled providing all the components are UL Listed for use in motor control centers.
RELAY PANELS
Relay panels can be furnished from 1 space unit to 6 space units with full width doors. The amount of vertical space required is generally determined by the number of terminal board points required or relay type used; when in doubt allow for a double vertical row of terminal boards.
These panels will be UL Labeled providing all the components are UL Listed for use in motor control centers.

➀ Two-pole THED breakers require a 3-pole space.
➁ Equipment rating is equal to the lowest interrupting rating of any circuit breaker installed.
NOTES:
Branch devices are plug-in for Type AL and bolt-on for AQ, AE and AD panelboards. Maximum of 42 circuits per panel.
The unit rating is the same as the lighting panel rating when:
A. The lighting panel is mounted as a separate motor control center unit but not connected to any power source within the motor control center. This does not reduce or affect motor control center short-circuit rating. The lighting panel must have a main breaker.
B. The lighting panel is mounted as a separate motor control center unit and factory connected directly (with no intermediate transformer) to motor control center bus through a feeder. The panel series rating must equal or exceed motor control center short-circuit rating.
C. The lighting panel is mounted as a separate motor control center unit and factory connected to a transformer unit in the motor control center. This does not reduce or affect motor control center short-circuit rating.
Ground fault CB not available in AL panels.
Lighting panel main bus is rated 1000 amps per square inch, alternate
800 amps per square inch is available.

DISTRIBUTION TRANSFORMERS
GENERAL
Open, dry-type transformers with primary thermal-magnetic circuit breaker or fusible switch with NEMA Class R (dual element) fuses are available in motor control center construction.
The accompanying tables give both single- and three-phase transformers normally mounted in motor control centers for use in supplying separate-source control circuits, panelboards, and power external to the motor control center.
Space units shown includes space necessary for the primary disconnect. One space unit equals 12 inches of vertical height. If transformers with taps are required, refer to the factory.
Primary disconnects rated 225-amperes and less stab into the vertical bus. Higher ratings use bolted connections.
Transformer secondary conductors are wired to a terminal board in the unit. One leg of 120-volt secondaries, the center point of
120/240-volt secondaries, and the Y-point of 3-phase secondaries are grounded unless otherwise specified.
NEC Article 450-3 covers transformer protection, other than motor control circuit transformers or special applications. The general requirements are:
Primary Protection Only
Primary Current
9 amps or more
2 amps to 9 amps
Less than 2 amps
Primary Protection Rating
125% or next higher standard rating per NEC Sect. 240-6
167% maximum
300% maximum
Primary and Secondary Protection
Secondary Current
9 amps or more
Less than 9 amps
Primary Prot. Rating
250% maximum
250% maximum
Sec. Prot. Rating
125% or next higher standard rating

POWER FACTOR CORRECTION CAPACITORS
DESCRIPTION
Motors and other inductive loads require two kinds of electrical current: Current which performs the actual work and reactive current which produces the magnetic fields necessary for the operation of inductive devices such as motors. Both types of currents produce system I 2 R losses. Capacitors installed near inductive loads can be used to reduce the reactive currents which flow through much of the system, thereby reducing I 2 R losses.
Low-voltage capacitors are generally three-phase units, deltaconnected, and are protected by current limiting fuses. The fuses disconnect the capacitor in the event of an electrical short, providing service continuity for the system and reducing the possibility of rupturing the capacitor case.
Power factor correction capacitors should be switched by a separate contactor (sketch d) under any of the following conditions:
• High inertia load.
• Open circuit transition reduced voltage starting.
• Wye-delta motor.
• Reversing or frequently jogged motor.
• Multispeed motor (2SIW, 2S2W, etc.).
Power factor correction capacitors should not be connected to the load side of solid state starters and drives. It should be noted that two-speed motor starters require separate contactors to switch in capacitors after a time-delay in order to avoid possible motor damage while the capacitors discharge. For the same reason, Wye-Delta starters have the capacitors applied after the delta connection has been made.
CAPACITORS SWITCHED WITH THE MOTOR
Capacitors used for power factor correction should be selected using the motor manufacturer’s application data.
When the capacitor is connected ahead of the overload relay
(sketch a, c, or d), the overload current elements should be selected using the full-load motor current and service factor values specified on the nameplate of the motor. When the capacitor is connected on the load side of the overload heaters (sketch b), lower rated heaters are required, since the overload relay in this case will respond to the vector sum of the motor and capacitor currents. Capacitors must not exceed the maximum KVAR recommended by the motor manufacturer for switching with the specific motor selected. The Capacitor Department, Hudson
Falls, NY, has published tables showing maximum capacitance and percent ampere reduction for specific GE motors.

In front-mounted configurations utilizing the 20-inch deep enclosure, capacitors may be mounted in the rear 10 inches of space behind the vertical bus. Rear access to the motor control center is required for servicing the capacitors.
Optional 240- and 480-volt blown fuse indicating lights are available. Visible through unit door.
SWITCHING CAPACITORS SEPARATELY
When a group of motors are so operated that some run while others are idle, a single capacitor bank (containing a number of individual units) can be connected to the motor control center bus to supply kilovars to the group. In these instances, a separate switching device is needed for the capacitors. The interrupting rating of the switching device should be at least as great as the short-circuit current available. Cable must be capable of at least 135 percent rated capacitor current. Switching device selections in the following tabulation are based on the continuous current of the capacitors.

Motor Control Centers Programmable Logic Control PLC
GENERAL
GE Fanuc Automation - Charlottesville, VA, has continually updated/improved its PLC products, which are mounted and wired in the Motor Control Center.
The Series Six PLC was the first in a succession of developments that established GE Fanuc in the marketplace. The Series
Six was the first PLC to employ the family concept. Other industry firsts include the Workmaster, the first IBM-based programmer; the
Series One, the first modular small PLC; Genius, the first distributed, intelligent I/O system; and the first embedded MAP 3.0 interface in a PLC. GE Fanuc’s newest line of PLCs, the Series 90-70 family, is the first PLC with truly open architecture. Thanks to the
VME bus back plane, many third party specialty modules are available to enhance the functionality of the Series 90-70.
GE Fanuc was one of the first companies in the United States to attain ESO 9001 registration from UL, CSA and BSI. This means that GE Fanuc has met the most comprehensive quality standard in the design, manufacturing and service of its products. Many of the
PLC packages have UL, CSA, and FM recognition.
SERIES 90-70
The 90-70 system has the most capability in the Series 90 family and is used for system PLCs as well as process lineups of MCC’s.
It has a wide range of input and output modules as well as extensive communication capabilities. With the GE Fanuc authorized third party VME modules, the Series 90-70 is exceptionally versatile
(including imbedded PCs, harddrives, motion control, etc.). The
90-70 is positioned to eventually supercede the Series Six Plus.
FIELD CONTROL
Modular design gives you more choices. Each field control station consists of a bus interface unit or BIU, an optional field control processor for local logic, up to four field terminal bases, and as many as eight field I/O modules. With field control, you can design a system that meets the precise needs of your application–and upgrade it easily as your application needs change.

GE Fanuc Field Control
GENERAL
With Field Control, GE Fanuc engineers have refined proven technology to create a truly modular system for decentralized I/O and control. Each station of a Field Control network can act as a stand-alone controller, allowing for physical separation of logical control functions and faster processing times. As a result, Field
Control is an ideal complement for the Series 90 PLC and Genius
I/O a single low-cost solution for a variety of application needs.
A Local Solution to a Field Logic
By providing simple logic solving at the local station, Field
Control produces shaarp increases in a system's raw speed and effieiency. Future versions of Field Control will accommodate additional programming options to build on these advances.
Iinitially, users will be able to program a Field Control station using standard GE Fanuc Logicmaster™ programming soltware used on Series 90-30 and Series 90-20 PLCs. In the future, they will be able to choose a programming language of their choice.
With Field Control, GE Fanuc engineers have created a single device that can accept field wiring and condition the signal for input to or output from the control system. There is no need for accessory terminal blocks installed solely to connect field devices with I/O. Designed to be installed and wired like a field terminal block, Field Control can reduce connections by up to one-holf.
The One Choice for Both Local Panel
Control and Decentralized I/O
Currently, control specifiers must purchase one I/O platform for local panels and a different platform for decentralized I/O. Field
Control is an open platform, equally at home in both applications.
Using the Genius bus and other available fieldbuses or communication options, Field Control provides an extremely cost-effective, space-saving option in both local panels and decentralized panel applications.
Open Architecture Provides the Solution for
Diverse Applications
GE Fanuc embraces open architecture for two reasons. It helps our customers make the most of their existing investment in industrial automation. And it enables them to take advantage of new products as they are developed.
To address the diverse needs of all our customers, GE Fanuc will be opening the field processor component to third-party partners to develop additional fieldbus interfaces. In addition, I/O protocol has been published, and we will be encouraging the development of third-party I/Os and accessories.

I/O SYSTEM
General
The Genius I/O, a system of inherently distributed inputs and outputs, is designed to interface to any number of industrial controllers, including GE Fanuc PLCs, and third party CPUs. It can be used as the only I/O on a System or it can be mixed with the present rack-type I/O. Genius represents a complete rethinking of the role of I/O in industrial control. Genius Blocks are UL, CSA, FM and
CSA hazardous environment approved. The Genius I/O system was made possible through two key General Electric technological innovations:
Smart Switch: A device with the built-in current and voltage sensors required for the extensive diagnostics available with
Genius I/O. The smart switch allows detection of faults not only within the programmable controller I/O system, but also faults in the coils and other actuator devices under the control of the programmable controller, as well as the signal path from pushbuttons and other input devices. No other technology provides this level of fault detection.
Communications Controller: A token bus local area network controller which allows Genius I/O devices to communicate over a single-shielded twisted wire pair, rather than via bundles of point-to-point wires required in conventional systems.
GENIUS I/O SYSTEM ARCHITECTURE
A simplified block diagram of the Genius I/O System is shown in
Figure 2. The PLC, CPU, and I/O rack shown are standard Series
90-70 units. The Genius serial bus connects I/O Blocks with a single shielded twisted pair up to 7500 feet from the Bus Controller.
Genius I/O Block
A microprocessor-based, configurable, ruggedized solid state device to which field I/O devices are attached. Measuring approximately 9” x 4” x 3”, I/O Blocks can be mounted virtually anywhere, such as in a draw-out unit of a motor control center or pushbutton station where it is common to have one input and one output per motor circuit. No separate rack or power supply is required. Field wiring is attached to a terminal assembly which separates from the removable electronics assembly. Thus, field wiring need not be disturbed to service the electronics. Due to the microprocessor and intelligent switching, inputs and outputs may be mixed arbitrarily on blocks. There are no dip switches nor replaceable fuses.
An EEPROM (Electrically Erasable Programmable Read-Only
Memory) is located within the terminal assembly. The EEPROM stores all user-selectable options and retains these selections even during POWER OFF conditions. It can be read by the electronics assembly at any time and altered by commands from either the
CPU or the Hand Held Monitor. The EEPROM is the only electronic device in the terminal assembly and has a long Mean-Time-
Between-Failure (MTBF).

Spectra Series™ and 8000-Line
Motor Control Centers Programmable Logic Control PLC
Genius I/O Block (Cont’d)
The electronics assembly contains the power supply, communications chip, microprocessor, smart switches, and other electronic components required to perform Genius I/O functions.
Each I/O Block is keyed to prevent the insertion of a non-matching electronics assembly into a terminal assembly wired for a different power. Once inserted, the electronics assembly automatically reads the content of the EEPROM and initializes itself to match the configuration originally established for the I/O Block in that position.
Table 1 lists the types of I/O Blocks currently available, as well as other basic system components.

Allow 18-inch height for the first two blocks, plus 12 inches for each additional set of two. This allows room for 120-volt power supply disconnect (or CPT). Maximum of 8 blocks per section, without ventilation.
Hand Held Monitor (HHM)
A portable diagnostic and configuration tool used for addressing, trouble-shooting, monitoring, scaling and configuring the I/O
Blocks. The HHM plugs directly into any block or into the programmable controller, or it can be attached to any location on the twisted pair communications link. It is supplied in a case suitable for you to attach to your belt, or it can be panel mounted using the mounting bezel included with each HHM. It has an alphanumeric
LCD display (4 lines x 16 characters) with microprocessor-driven prompts available in English, German, French, or Italian. A key feature of the HHM is its ability to manually perform functions and force discrete and analog I/O, whether or not there is a programmable controller connected to the system. This greatly facilitates system check-out prior to full-scale operation.
The HHM includes:
–An LCD display capable of displaying 16 characters per line on four separate lines.
–Four display-labeled soft keys.
–A decimal keypad, including sign and decimal point keys.
–Four fixed-function keys.

I/O SYSTEM
SERIES SIX BUS CONTROLLER
The Bus Controller serves as the interface between the Genius
I/O systems and the industrial controller.
Bus Controllers are available for Series 90-70, Series 90-30 (for communications), Series Six PLCs, personal computers, DCSs,
Industrial Robots, GE Drive Systems, and others.
Genius I/O Bus
To connect Genius I/O elements together is a 150 kbit/sec serial token passing bus communications link formed by daisy-chain connection of twisted pair wire. It has high noise immunity (1500 volt common mode) and its operation is not affected by any block attachment, removal or failure. Each data bit is triply encoded for data integrity; error detection is further improved via cyclical redundancy check (CRC). Bus errors are reported automatically.
This link requires only one pair and can be Belden type 9302 (or factory approved equivalent) up to 100 feet (30 meters) in total length, or must be Belden type 9182 or Alpha type 9823 (or factory approved equivalent) up to 7500 feet (2258 meters). Belden type
9182 or equivalent is used in motor control center equipment.

Diagnostics
The Genius I/O system provides advanced diagnostic capability. Error detection for discrete and analog circuits is summarized in
Table 2. Such detection includes a variety of block failure modes, bus failures and failures within the Bus Controller. Of greater significance, however, is the diagnostic power for the attached I/O devices. On discrete blocks, the system detects open wires, short circuits, overloads, and a variety of other malfunctions which are beyond the power of conventional programmable controllers to detect. Many faults may be detected before they cause a malfunction in equipment. The Genius I/O can detect the integrity of a control circuit before the circuit must actually be energized by periodic
“pulse-testing” under microprocessor control within a Genius I/O
Block. Over temperature sensors are also built into each circuit.
On the analog blocks, the Genius I/O can detect an input open wire, mix high-level analog signals on one I/O Block (±10 volts DC,
±5 volts DC, 0-10 volts DC, 0-5 volts DC, 1-5 volts DC, or 4-20 mA), establish linear conversions from analog values to engineering units, process high-level and low-level alarms, and detect overrange and underrange analog signals. Analog blocks also allow you to establish different filter delays on inputs: short filter delays
(5-10 msec) for fast system response in controlled low-noise environment or longer filter delays (20-1000 msec) to reject electrical noise in harsh environments. All of these faults are automatically reported to the HHM or CPU.

CONNECTIONS
PLC CONTROLLED STARTERS
A combination motor starter will require a minimum of one
INPUT and one OUTPUT per starter. As shown in Figure 5, the
OUTPUT is connected between the starter coil and the fused, ungrounded leg of the control voltage source (terminals 3, 1). The
INPUT connection is made between the starter “Seal contact” and the grounded leg of the control voltage source (Terminals 2, X
2
).
The INPUT monitors the status of the seal circuit to independently verify that the starter has closed.
Fig. 5. INPUT and OUTPUT Connection
When an H-O-A switch is used with PLC I/O, the configuration will appear as shown in Figure 6. Note: as mentioned previously, the INPUT monitors the status of the starter’s seal circuit in the manual mode as well as the PLC (automatic) mode.
OPTIONAL INPUTS/DIAGNOSTIC
Additional INPUT connections can be made to monitor the specific status of combination starters and feeders to provide further diagnostic information to the process operator and maintenance personnel.
1. The status of the overload relay can be monitored. An electrically-isolated, normally-open auxiliary contact can be ordered with the GE 300-Line overload relay and an additional PLC INPUT can be wired in series with it.
2. A PLC INPUT can be connected between terminals 1 and X2 to monitor the availability of control power to the starter unit.
STARTER UNITS WITH SEPARATE-SOURCE
CONTROL VOLTAGE
INPUT and OUTPUT connections are shown below (see Figure
7) for units arranged for separate-source control.
INPUT– A common (non-isolated) INPUT can be used if all X2 terminals are wired together.
OUTPUT– As required by NEC Article 430-74, if a disconnect auxiliary contact and/or control circuit fuse (FU) is included with each starter, then the OUTPUT must be the isolated type. However, if the auxiliary contact and fuse are omitted, a common OUTPUT module can be used. With common output modules, interposing relays are required with NEMA Size 3 and 4 starters.
Note: NEC article 430-74 can be met with GE’s standard split-type control terminal boards on all draw-out units, or with GE’s pull-apart terminal boards.

SURGE SUPPRESSORS
In cases where excessive noise is present on the control line or hard interlocks which will operate often (in series with PLC OUT-
PUT), surge suppressors are recommended.
ISOLATED VERSUS NON-ISOLATED OUPUTS
Isolated Outputs
GE’s isolated OUTPUTS can be used for direct control of NEMA
Size 1 through 4 combination starters without the use of an interposing relay. The contactors of GE’s standard NEMA Size 5 and larger starters are operated at line voltage with interposing relays operated from the secondary of the control transformer.
Non-isolated OUTPUTS
NEMA Size 1-2 starters may be operated directly from common
PLC OUTPUT cards. The continuous current rating of GE’s non-isolated OUTPUT module requires an interposing relay for NEMA Size
3 and larger starters. Check the module ratings for inrush and continuous values.

ADJUSTABLE SPEED DRIVES
GENERAL
As a vehicle for controlling multiple motor functions, the Motor
Control Center has become the logical place to mount variable speed drives. However, the application of these drives is not a simple selection process, and the following is an explanation of some of the variables involved.
A drive must have ventilation. The basic power switching components are transistors, which are mounted on finned heat sinks. Although the drive may be operating at 95% efficiency, the
5% (±) normal heat loss cannot be enclosed in the MCC without exceeding the safe operating temperature (50°C). Standard mounting is ventilated (NEMA 1 or 1A only.)
A drive is electronically controlled. The new generation of PWM drives are all microprocessor based. Although well shielded from stray noise, they require careful wire routing, and in some cases shielded wire runs to avoid “nuisance” problems. Control wires should be run separate from power leads. If they must cross, try to keep them at right angles to minimize the induced fields
(noise).
A drive creates noise on the power system. Although we use reactors to minimize system disturbances, a drive will create harmonics on the power/system (both at the motor and at the transformer). If sensitive computer systems are to be utilized, they should be isolated from the drive’s source. Likewise, the harmonics created at the motor may cause the motor to run hotter than expected. Standard motors should be derated 10% when used with a drive. We recommend GE’s high efficiency ENERGY SAVER ® motors for drive applications. See motor application data, SH. G-3
A drive must have short circuit protection. Since a drive is subjected to higher available short circuit currents in an
MCC, (vs. a wall mounted unit) additional components such as current limiting fuses and reactors are utilized. See typical one line sketch.
A drive can provide significant energy savings. When a fan or pump is utilized on a system with variable flow rates, whether measured in gallons per minute or cubic feet of cooling air per minute, a variable speed drive is the most efficient means of control. Since a variable torque load requires significantly less energy when operated at lower speed, the energy savings can be in the 25 to 50% range when compared to a full voltage motor using dampers or valving to reduce its output. (The amount of savings depends, of course, on the amount of time the motor can be used at the reduced speed.)
LINE REACTORS
The available power source connected to the Drive is not to exceed 500KVA. If the ac power source is greater than 500KVA and the Drives rating (HP) is less than 10% of the power source's
KVA; ac line reactors will have to be installed in L1, L2, and L3 power leads of the Drive.
AF300E$™ Drives
LOAD FILTERS
IGBT drives create voltage spikes at the motor. Motor insulation rating must be higher than these peaks. Motor should meet NEMA MGI part 31. If not, load filters may be required.
Refer to factory for analysis.

MOTOR APPLICATION DATA
Harmonic Derating
AC motors have traditionally been applied as constant speed motors, so there is little published information on reduced speed efficiencies, especially when operated with a non-sinusoidal supply such as an inverter. The harmonics present in the PWM inverter output increase motor losses and thus motor heating. General
Electric Energy Saver® motors, designed for high efficiency and improved thermal characteristics, may be applied at nameplate rating for variable torque duty, such as centrifugal fans and pumps, for 4 and 6 pole ratings. Standard AC motors designed for 60 Hertz operation should be derated 10% for variable torque duty. For constant torque applications, Energy Saver and standard design motors should be applied per Fig. 1. For other applications refer to the Company.

HOW TO SELECT DRIVES
1. Types of Load
In selecting inverters, load patterns of machines should be known in advance. Generally, loads can be categorized into the three types shown below. Estimate or obtain the point marked 0 as indicated. This defines maximum torque and the maximum or minimum speed requirement of the driven equipment. Calculate the required motor HP by substituting the maximum torque and rated motor base speed in equation (1).
HP = Required HP
T = Torque in lb./ft.
N = Speed in RPM
Select the proper motor using the data from motor application brochures, identify the motor full load current and select the inverter which meets or exceeds the motor full load current requirements.
2. Motor Speed Range
Motor synchronous speed is determined by the following equation:
Sync. Motor Speed =
Frequency
120 X Applied
Number of Motor Poles
Induction motors operate at a somewhat slower speed than synchronous speed due to slip, which is generally 2-3 percent of synchronous speed.
If the application requirements call for higher or lower speeds than can be obtained by using standard motors following these application guidelines, gear increasers or reducers should be considered.
3. Multi Motor Drives
Multiple motors can be driven simultaneously by one drive unit.
In order to select the proper inverter, total the individual motor full load currents sums and multiply the sums by a factor of 1.1. Select the inverter than can deliver the total current calculated. Each motor will require individual overload relays.
4. Acceleration Time
Acceleration time is programmable. If the programmed setting calls for a faster acceleration than the drive system is capable of, the unit may trip due to an overcurrent condition. Therefore, the actual time to accelerate the driven load should be calculated using the following equation and the acceleration time setting should be adjusted accordingly.
TA =
(Wk 2 X
#
N)
308 (T X 1.2)
Where:
TA = Time to accelerate the driven load (in seconds).
#
N = Change in speed (in RPM)
WK 2 = The total system inertia reflected to the motor shaft.
Includes motor, machine gears (in ft./lbs.
2 )
T = Motor full load torque (lb./ft.)
When using a drive in a conventional constant speed machine application where a full voltage starter has been used, the acceleration time should be set longer than the original machine. This is because the maximum allowable current that the drive can deliver is 150 percent of rated, while full voltage starters deliver 600-800 percent. This means that the drive delivers a “soft start” and thus reduces starting torque over that of a full voltage starter, which naturally yields a longer acceleration time.

5. Deceleration Time
Deceleration time is programmable. If the programmed setting calls for faster deceleration than the drive system is capable of, the unit may trip due to an overvoltage or overcurrent condition.
Therefore, the actual time required to decelerate the driven load should be calculated using the following equation and the deceleration time setting should be adjusted accordingly.
TD =
(Wk 2 X

N)

Where:

SOLID STATE STARTERS
GENERAL
The GE solid-state starter is a reduced-voltage starter that provides smooth, stepless controlled acceleration of AC squirrel cage induction motors from standstill to full speed. It provides controlled extended starting times by supplying continuously varying voltage to the AC motor from zero to full voltage. The solid-state starter can be supplied in 8000-Line motor control center construction to combine the advantages of solid-state starters together with conventional electromechanical motor control.
ADVANTAGES OF SOLID-STATE STARTERS
• Inexpensive conventional NEMA design B, C, or D induction motors.
• Lower maintenance cost through elimination of power line transients, excessive line voltage dips as well as high impact torques transmitted to mechanical linkages.
• Lower operating costs versus equivalent electromechanical starters together with a concurrent reduction in starter size and power requirements.
• Starting characteristics can be matched to the specific application for smooth startup and protection.
• Automatic regulation and control of starting currents. Continuous monitoring of motor line current provides automatic shutdown in the event of locked-rotor or mechanical jamming of couplings, etc.
Description
GE’s advanced ASTAT-CD™ solid state reduced voltage starter
— sometimes called a soft starter — is the industry’s first solid state starter featuring microprocessor controlled digital technology, digital adjustment, digital alphanumeric display and error code traceability. These features, coupled with the optional communications module, allow the ASTAT-CD to be effectively incorporated into distributed control systems and automated plant processes. Up to 16
ASTAT-CD solid state reduced voltage starters can be coupled on a single bi-directional serial RS422/485 computer interface.
The ASTAT-CD starter’s advanced control technology individually fires each phase in a special selected sequence to offer reliable performance for the smooth acceleration of all types of loads.
reducing shock to mechanical components, thereby extending component and motor life.
Each starter consists of an electronic control module and a power base consisting of six SCRs arranged in anti-phase parallel pairs for optimum performance. The ASTAT-CD starter’s deceleration ramp is programmed with non-linear characteristics to more closely match variable torque loads to help eliminate water hammer and stress on couplings, plastic pipe and check valves in pumping applications.
The ASTAT-CD starter offers many standard features including energy savings mode with override, adjustable current limit, motor overload protection, kick start, loss of load detection, and loss of phase protection. These, plus many additional features, make the
ASTAT-CD starter the obvious choice for reduced voltage starting applications.
Application
ASTAT-CD solid state reduced voltage starters are used to reduce or eliminate mechanical shock and stress on mechanical components such as vee belts, gear boxes, chain drives, couplings, transmissions and shafts. ASTAT-CD reduced voltage starters are used to reduce brownout conditions and may limit energy and demand charges. ASTAT-CD solid state reduced voltage starters are used to control process lines, to smoothly accelerate and decelerate loads, to position and move loads and restrict process surges.
Typical applications include: compressors, pumps, belted equipment, centrifuges, conveyors, cranes, crushers, winches, fans/blowers, extruders, flywheels, hoists, laundry extractors, mixers, packaging equipment, machine tools, shears, saws, spinning frames, textile machinery, winders and wire drawing machines.
Note: When installed in the Motor Control Center, the “standard” ASTAT-CD starter is rated for motors with a 1.15 service factor. It provides 300% motor full load current for 30 seconds acceleration, or, when the overload curve is selected for heavy duty, will also provide 450% motor fla for 30 seconds. The 500% rated starter has been derated to provide extra capacity for those loads requiring heavy starting currents due to high inertia, or conveyor type applications.
The electronic OL on the standard duty ASTAT is suitable for motor protection when programmed at 300%. When using 450%
(or 500%) acceleration limits, always verify motor capacity for extended acceleration time with motor manufacturer. Separate OL relay required with 500% ratings, since ASTAT is derated for extra capacity beyond standard OL curves.

Standard Features
DIGITAL TECHNOLOGY
Provides precise phase control of the back to back SCRs over each
1
/
2 cycle. Special ASTAT-CD™ design allows initial motor torque to be adjusted from 10% to 90%.
DIGITAL CONTROL PANEL
Displays setup and operating parameters with alphanumeric display. Provides accurate setting of parameters and visible indication of starter status and fault codes.
MOTOR THERMISTOR PROTECTION INPUT
Used with motors protected with PTC thermistor. Trips within
200msec when resistance is higher than 2800-3200 ohms. Resets when resistance falls below 1000 ohms.
STALLED ROTOR PROTECTOR
Power is removed from motor when stalled condition exceeds
200msec. Provides motor protection and process feedback.
SOFT STARTING
The most frequent application for the ASTAT-CD starter. Provides a linear increase in voltage at the motor terminals, eliminates starting shock to the load and reduces stress on mechanical components, such as gears, belt drives, piping and valves.
THREE SEGMENT RAMP
The three segment ramp consists of (1) the initial voltage ramp which lasts for 5 cycles and brings voltage from 0 to the preset initial pedestal voltage (30%-95%). (2) Acceleration ramp - increases motor voltage from preselected initial voltage to 100% voltage over selected acceleration time period. (3) Fast ramp - brings motor voltage to 100% if motor reaches full speed prior to end of acceleration ramp.
SNUBBERS
RC network connected in parallel with SCR to protect against commutation spikes, thereby limiting harmonics being fed into power lines.
MOVs
Metal oxide varistors used to protect electronic components against external voltage spikes.
ERROR TRACEABILITY
Displays last 4 error codes on alphanumeric display. Affords feedback for corrective action.
PHASE LOSS PROTECTION
Removes power from motor terminals in 3 seconds upon detection of phase loss. Provides additional protection against motor burnout.
ELECTRONIC OVERLOAD RELAY
Overload relay selectable trip characteristic - for standard (300%,
30 sec.) or heavy duty (450%, 30 sec.) applications. Provides accurate, repeatable, reliable motor protection.
KICK START
Used to start loads with a high breakaway torque (belted conveyors, extruders, mixers). Feature may be engaged (95% voltage for a time of 1-999msec, or feature may be disengaged for applications not requiring kick start.
THERMAL OVERLOAD MEMORY
Overload relay retains memory of overload conditions to closely profile motor winding thermal condition to insure adequate protection under repetitive overload conditions. Memory is maintained as long as the control power remains applied to the soft starter.
SCR OVER TEMPERATURE PROTECTION
Heat sinks are fitted with thermostats to protect SCR against fan failure. (Trip @ 80°C ± 5°; reset @ 50°C ± 10°C)
CURRENT LIMIT
The motor current may be limited with an adjustable current range from 100-450% starting current. Used to reduce starting current to limit brownout/low voltage conditions during motor starting.
SOFT STOPPING
Allows motor driven load to be brought to rest over an adjustable time period. The enhanced soft stop pump control allows pump shut down while limiting pump system water hammer and fluid surges.
ENERGY SAVING MODE
Reduces motor voltage under no load or low load conditions, thereby reducing reactive power required by the motor. Motor voltage is automatically increased as the load is increased. Feature may be disengaged when not desired.
DC BRAKING
Braking current is adjustable from keypad for a range from 50-
250% of the operational current for a predetermined time (0-99 seconds). Also keyboard selectable, feature may be disengaged when not desired. Requires external contactor.
FREQUENCY ERROR DETECTION
Electronic frequency sensing will not allow start to begin load ramp-up if frequency is < 48Hz or > 62Hz, providing protection to the motor and starter should frequency be excessively out of tolerance.
LONG START TIME PROTECTION
If current limit is set too low and/or starting time is longer than 240 sec. or two times the preselected acceleration ramp time, it is assumed that the motor heating could be excessive. The ASTAT-
CD starter provides long start time protection and disconnects the load under these conditions.
3 OUTPUT RELAYS
• Run/fault relay – user configurable from keypad. When configured as run, relay contacts close upon initialization of start command and open when stop order is given or the starter shuts down due to a fault condition. When configured as a fault, the relay closes when control power is applied and opens only if a fault condition is detected.
• At speed relay (end of ramp), contact closes when starting ramp voltage reaches the end of ramp, indicating the motor is running at full speed.
LOSS OF LOAD DETECTION
Prevents motor burnout for application in which driven load is also cooling motor (for example a submersible pump motor). Time delay is 10 seconds after load loss, feature is DIP switch selectable.
• DC brake relay – contact closes to supply voltage to external injection braking contactor when brake command is given.

Optional Features
SLOW SPEED
Factory option which, when supplied, is engaged by DIP switch selection. DIP switch selection allows user to engage either 7% or
14% speed to align or position loads.
TACHOMETER FEEDBACK
Factory option which, when supplied, provides linear speed ramp independent of load torque. Speed feedback is provided by user supplied tachometer attached to driven shaft. A voltage transducer is required to match tachometer voltage to required input voltage range (0 to 5VDC). Option is DIP switch selectable when supplied.
COMMUNICATIONS RS422/485
Factory option which, when supplied, allows setup and readout of starter parameters and operating conditions via serial computer connection. Up to 16 ASTAT-CD starters may be monitored and controlled on a single serial interface. Starters are DIP switch identified on communications board and maintain identity via communications link. Each starter may be given its own name/location identity on the computer screen. Each starter may be configured either locally through enabling local control or remotely at the computer interface terminal. If local setup is required, the setup parameters may be polled by the computer terminal and the configuration saved for remote control.

Electronic overload. The solid-state reduced voltage starter provides overload functions for both starting and running protection. An overload condition automatically de-energizes the starter and registers a fault. The overload function is selectable for either standard or heavy-duty motor operation. When the relay trips, thermal memory is maintained as long as the control voltage remains applied to the starter. The overload relay is suitable for either heavy-duty starting (450% current, 30 seconds) or standard-duty starting (300% current, 30 seconds). The overload has the following trip time characteristics:

Mag-Break Motor Circuit Protectors
➁
Mag-Break motor circuit protectors were specifically developed to provide accurate and fast clearing of low-level faults, the type most prevalent in motor circuits. Because they are designed expressly for motor circuits in combination with overload relays, they minimize damage to motors and motor-control apparatus in addition to protecting motor branch-circuit conductors.
Continuous-current ratings and adjustable instantaneous trip ranges have been designed to meet NEC code requirements concerning motor full-load and locked-rotor current. The instantaneous-trip point can be set low and precisely (just above motor inrush) assuring fault protection and eliminating nuisance tripping.
To minimize circuit damage, select precise, optimum trip points.
Each pole of the Mag-Break breaker contains a current sensing element to trip the breaker instantaneously when the pre-selected current setting is exceeded. Mag-Break’s unique magnetic system permits independent factory calibration of both HI and LO ends of the trip range. This feature provides field adjustability with superior accuracy and repeatability at all Mag-Break trip scale positions.
Mag-Break is field adjustable by means of simple screwdriver adjustments on the front of each breaker. The field-adjustable setting is continuous over the entire range from HI to LO and each breaker rating label contains a table converting setting position to amperes. An overcurrent on any pole will cause all three poles to trip simultaneously, thus preventing costly single phasing problems.
Features of Mag-Break motor circuit protectors include:
• No costly equipment modifications are required. Mag-
Break motor circuit protectors are mechanically interchangeable in all respects with conventional circuit breakers of the same frame size.
• Conventional circuit breaker accessories such as undervoltage release, shunt trip and auxiliary switches can be used.
• Mag-Breaks include the Verifier™-Twist-to-trip – permitting the mechanical simulation of overcurrent tripping through actuation of linkages and latch surfaces not operated by the ON-OFF handle.
Experience has shown that protective devices in industrial applications better maintain their original protective characteristics when regularly exercised.
• Widest trip setting ranges in the industry-specifically designed to meet control flexibility demands of modern motor installations.
• Highly accurate calibration over the entire range of trip settings.
•
“
Designed in
” withstandability for use with slow trip overload relays – meets

• Mag-Break covers an area of motor circuit protection not provided by any other class of device. In the range of 7-
35X rated current, the region where most motor circuits failures begin. Mag-Break acts instantly to remove the fault from the system. At 13X (the maximum setting allowed by the NEC) other devices take 50 to 400 times as long.

• Current Limiter (optional feature) – The Type TECL is a fusible current-limiter attachment that bolts to the load end of the Type Mag-Break motor circuit protector. The limiter provides for up to 100,000 amperes IC at 600 volts AC and is coordinated with the TEC so that normal short circuits will be cleared in the usual fashion. Only the unusual circumstances of a high fault will cause the limiter to function. Type TBC
Mag-Break motor circuit protectors provide 100,000 amperes IC on
225 ampere and larger frame sizes. Type TBC protectors are similar in size and operation to Tri-
Break circuit breakers and employ current limiters integral to the frame as opposed to an add-on limiter such as the Type TECL. TECL is used for 600V applications.

Spectra RMS –
Mag-Break Motor Circuit Protectors
Interchangeable Rating Plug.
Spectra RMS Mag-Break motor circuit protectors use the same snap-in rating plugs as fully configured (long-time trip function) Spectra RMS circuit breakers. Each rating plug defines the range of instantaneous-trip settings available to the circuit breaker through its trip setting adjustment.
Trip Setting Adjustment. The solid-state instantaneous-trip circuitry of the Spectra RMS Mag-Break motor circuit protectors has a single, multi-position adjustment at the front of each breaker.
Changes in settings vary the instantaneous-trip and tracking short-time characteristics. The Mag-Break motor circuit protectors differ from a fully configured circuit breaker by providing only an instantaneous and tracking short-time trip function.
Accessory Pockets. Spectra RMS Mag-Break motor circuit protectors have the same accessory pockets and use the same internal accessories as Spectra RMS circuit breakers. This important capability allows field modification of Mag-Break units with shunt trip, undervoltage release, bell alarm or auxiliary switch accessories, in any combination, without affecting UL Listing status.
Spectra RMS Rating Plugs
Use of the same UL Listed interchangeable rating plugs for both
Mag-Break and fully configured Spectra RMS circuit breakers expands the flexibility of the entire Spectra RMS family of products. The advantages of interchangeable rating plugs with
Spectra RMS circuit breakers are inherent to Spectra RMS Mag-
Break units, which permit wider ranges of motor ratings to be protected by a given breaker frame size.
Spectra RMS Mag-Break Trip Unit Characteristics
Spectra RMS Mag-Break motor circuit protectors provide positive, reliable, and cost-effective instantaneous, with short-time tracking, overcurrent protection to those circuits where long-time overload protection is supplied by thermal or solid-state overload devices.
Motor Circuit Short-Circuit Protection
When a squirrel-cage induction motor is first energized, a high value of magnetizing inrush current flows for the first few cycles, followed by a substantially reduced current flow while the motor accelerates to its rated speed. Typically, the magnetizing inrush current may be 10 times rated full-load current, for normal efficiency motors and as high as 14 times rated full-load current for high-efficiency motors prior to the first five to eight cycles.
Magnetizing inrush current is followed by a “locked rotor” current of 5 to 6 times rated full-load current during 0.1 to 10 second acceleration phase – with current rapidly declining to full load amperes as the motor nears rated speed.
Optimum instantaneous protection would have a two-tiered tripping characteristic. A high value of current would be tolerated for a few cycles, followed by a lower, sustained trip setting.
That is exactly what is found in the Mag-Break tripping characteristic.
Use of this two-tiered time-current curve prevents nuisance tripping due to magnetizing inrush current, without compromising superior short-circuit protection during motor acceleration as indicated on page H3.
The figure below illustrates the most popular application of
Mag-Break motor circuit protectors. This time-current curve shows a plot of motor current versus time (Curve C) for a threephase squirrel cage induction motor. The shaded portion of the time-current curve (above Curve A) indicates a region of operation that could produce permanent damage to either the motor, its feeder conductors, or both. The trip characteristics of the motor starter’s overload relay is shown as Curve B. The overload relay provides both long-term overload and stall protection. However, the overload relay does not protect the system from short circuits in either the motor or its feeder conductors.
Curve C is a plot of motor current during a worst-case start
(e.g., low line voltage, highest anticipated required load torque, etc.). Curve D is a plot of the Spectra RMS Mag-Break motor circuit protector’s tripping characteristic.
With the addition of the Mag-Break motor circuit protector, the motor circuit now has protection against short circuits. Stall and long-term overload protection is provided, in this example, by the motor starter’s overload relay.

Spectra RMS Molded Case Switches
Construction. The family traditions of ruggedness and dependability are continued in the Spectra RMS molded case switch line.
These units provide a circuit disconnect function using the compactness of molded case circuit breaker construction. The operating handle actuates all three poles of the switch using the same common trip bar of Spectra RMS circuit breakers and Mag-Break units.
Termination Lugs. Snap-in termination lugs used with SE- and SF-
Frame Spectra RMS circuit breakers are used interchangeably in
Spectra RMS molded case switches. SG- and SK-Frame molded case switches use the same bolt-on termination lugs used with
Spectra RMS circuit breakers.
External Accessories. The full range of external circuit breaker accessories offered for use with Spectra RMS circuit breakers and
Mag-Break motor circuit protectors, are available for molded case switches. In addition, plug-in bases, motor-operated mechanisms, mechanical interlocks, and the full complement of external handle operators (STDA, TDR and TDM) are available for use with Spectra RMS molded case switches.
Fixed-Trip Setting. The Spectra RMS molded case switches are equipped with a fixed Hi-set instantaneous trip setting whose values are shown in the table below.

Spectra RMS Molded Case Switch Applications
Molded case switches are inherently horsepower-rated. By virtue of the UL489 six-times rated-current overload test, they can be used as motor circuit disconnects where overload and short-circuit protection are provided by other protective devices.
A common application of Spectra RMS molded case switches is illustrated below. The figure shows a system containing three branch circuits.
Branch circuit 1 uses a Spectra RMS Mag-Break motor circuit protector, in conjunction with the overload devices of the motor starter, to protect the motor and the conductors of that branch circuit. Branch circuits 2 and 3 use fully configured Spectra RMS circuit breakers to provide instantaneous, short-time and longtime protection for both branch-circuit conductors and loads.
Spectra RMS molded case switches are excellent circuit disconnect devices for those applications where both the advantages of molded case switch construction are desired, and where the available short-circuit current is less than the switch withstand rating.
All Spectra RMS molded case switches are UL Listed and tested per UL Standard 1087 for molded case switches. The short-circuit withstand ratings are based upon three cycle tests. Thus the
UL Listed upstream overcurrent protective devices (i.e., low-voltage circuit breaker equipped with instantaneous-trip functions, insulated-case circuit breakers, molded case circuit breakers or fuses) can be used in conjunction with molded case switches.

HPC High-Pressure Contact Switches
Construction Features
GE Type HPC switches are UL Listed in accordance with Standard
977, Fused Power Circuit Devices. The over-center toggle mechanism provides stored energy, quick-make/quick-break operation.
Multiple spring-loaded high-pressure current-carrying contact arms and an arcing contact arm provide excellent current carrying capability without sacrificing high interrupting fault performance.
These switches can interrupt, on a make and break basis, a minimum of 12 times their nameplate rating without fuse assistance at
600 volts AC. Complete HPC switch and Class L fuse coordination is therefore achieved for all levels of fault current up to 200,000
RMS amperes symmetrical at 600 volts AC maximum. Type HPC switches used as service disconnects comply with the National
Electrical Code Article 230-98 and Article 230-95 for adequate short-circuit current and ground-fault protection. HPC switches with integral ground fault, when provided with 120 volts AC external control power, permit compliance with NEC Article 230-95, which requires ground-fault protection system testing when first installed.
• High Durability–Safety of Operation–High dielectric strength, glass reinforced insulating case.
• High Interrupting capability–Arc chute of unique construction suppresses arcs and cools gases rapidly, providing quick arc interruption and extended switch life.
• High Transient Voltage withstandability– Interphase partitions mesh with switch cover to completely isolate each pole.

Power BreakII Insulated Case Circuit Breakers
General Description
The GE line of Power Break II insulated case circuit breakers offers the rugged, reliable type of system protection critical for heavyduty applications. Power Break circuit breakers are rated up to
200,000 amperes RMS symmetrical interrupting capacity without fuses or current limiters. The Power Break II design consists of two physical envelope sizes: 800, 1600, 2000, 2500; and 3000,
4000 Amp. frame sizes.
Power Break II is a versatile breaker, designed for a wide variety of applications with features such as temperature insensitive trip units, push-to-open and -close buttons, standard padlocking provision, maximum three-cycle closing time, field installable rating plugs to change ampere ratings, UL listing, plug in field installable accessories, and easy-to-operate two stage pumphandle, stored-energy operating mechanism capable of change after close.
MicroVersaTrip Plus Trip Unit
The enhanced MicroVersaTrip Plus trip units utilize a digital, LCD display with a five-button keypad to provide local set-up and readout of trip settings. A built-in battery allows cold set-up (no phase or control power required). A three-phase ammeter and trip indicators are standard, as is a hinged plastic cover with provisions for sealing to allow tamper-resistant installation. The trip unit digitally measures the current waveform in each phase to determine the true RMS value of the current, regardless of the waveshape.
MicroVersaTrip Plus trip units provide accurate, predictable overload and short circuit protection for distribution systems that include variable speed drives, rectifiers, induction heating, and other loads that cause high harmonic distortion as well as standard circuits. They provide maximum breaker-to-breaker selectivity and custom load protection. Short-time and ground fault functions include the flexibility of coordination with or without an l
2 t ramp and are also available with high range instantaneous.

Spectra RMS Circuit Breakers and THED/TEDL Circuit Breakers
Features
Spectra RMS
SE150, SF250, SG600 and SK1200 circuit breaker frames have a digital, solid state, RMS sensing trip system with field installable, front-mounted rating plugs to establish or change the breaker ampere rating. Adjustable instantaneous with tracking short-time is standard on all frames including SE150.
MicroVersaTrip Plus Trip System
SG600 and SK1200 are optionally available with the
MicroVersaTrip Plus trip system which offers expanded functionality in the same space-saving size of standard Spectra RMS breakers: able rating plug establishes the instantaneous pickup range (with tracking short-time) but does not change the frame ampere rating.
• Spectra RMS molded case switches have a fixed, high-set instantaneous trip (without tracking short-time function) and have short circuit withstand ratings equal to their equivalent breaker frame size interrupting rating in most cases.
• RMS breakers are ambient insensitive. Trip times will not vary over the range 10-50° breaker ambient.
• Spectra RMS breakers contain no parts that would support fungus growth and are, therefore, inherently fungusproof.
Standard
• 3-phase Ammeter with ±4% accuracy.
• Adjustable Long Time (L) pickup, 0.5-1.0X, and delay (3-4 bands).
• Adjustable Instantaneous (l) pickup, 1.5-10X.
• Local Overload and Short Circuit Trip Indicators (T) with overload pickup warning.
• Interchangeable trip rating plugs with test set jack for
TVRMS test set.
• Digital LCD display with four-button keypad for function selection and set point adjustment and sealable, clear
Lexan ® cover for tamper-resistant settings.
• True RMS sensing for accurate response to high harmonic content waveforms.
• EMI immunity per ANSI C37.90.
Other MCCB Features
• Broad product line to meet virtually any application need.
• Reduced downtime. A tripped breaker is easily spotted and can be immediately reset after the fault has been corrected.
• Eliminates single phasing. A common trip bar disconnects all poles simultaneously on both overloads and short circuits.
• Offers application flexibility through the use of a wide variety of accessory devices and special attachments.
• Repetitive operation — no fuses to replace.
• Breakers can be repetitively tested. Fuses must be destroyed to confirm calibration accuracy.
Optional
• Adjustable Short Time (S) pickup, 1.0-9.0C, and delay (4 bands) with I
2 t ON/OFF selection.
• Adjustable Ground fault (G) pickup, 0.2-1.0S, and delay
(4 bands) with I 2 t ON/OFF selection and trip indicator.
The 4 short time and ground fault delay bands provide broader system selectivity.
A complete circuit breaker consists of a UL Listed circuit breaker frame and a rating plug (UL Listed interchangeable trip breaker unit). Terminal lugs for cable connection are available if required.
• All frames use the same UL listed, field installable internal accessories (auxiliary switch, shunt trip, undervoltage release and bell alarm).
• All frame sizes have maximum UL listed interrupting ratings of 200 kA @ 240 volts AC and 100 kA @ 480 volts
AC with 600 volts AC ratings to 65 kA depending on frame size. UL listed current limiting versions are provided through the SG600 frame for the 65 kA @480 volts AC and the 100 kA @ 480 volts AC models, with no increase in physical frame size.
• Spectra RMS Mag-Break instantaneous-only motor circuit protectors also use the same digital, solid state trip unit and rating plugs as the circuit breakers. The interchange-

Ground Break Systems
Type TGSR Protective Equipment
Description
The Ground Break system of solid-state ground fault signaling relays, sensors and monitor panels provides a new dimension in power-system protection. These components can be combined to operate at lower magnitudes of ground-fault current and shorter time delays than conventional over-current protective devices. The built-in memory function integrates intermittent faults with time providing protection against low-level arcing faults. The components which comprise a complete system are:
Solid-State Relay
Used in conjunction with devices having an electric trip, or shunt trip, this relay will sense ground currents and cause the interrupter to open when these currents reach a preselected value for a preselected length of time. Optional zone selecting interlocking is available for a fully coordinated system. This type of relay initiates an instantaneous trip when a fault occurs in its own zone. In addition, it will block upstream zone selective relays for a pre-set delay time to allow the downstream breaker to clear the fault.
Monitor Panel
Provides a ground fault indicator, control power indicator and TEST and RESET buttons. The control circuitry offers the ability to test the complete Ground Break system with or without tripping the interrupter.
Current Sensor
Solid- or split-core construction for easy installation, includes an integral test winding for checkout of the complete system. A large variety of window sizes are available.
System Selection Guide
Sensors may be used 1 per phase or any other combination. For this type of use all outputs except “T” should be connected in parallel. When sensors are used more than 1 per circuit the thermal rating (current) must not be less than the maximum phase current.

General
These Class 1 Model GFM Ground Fault protection systems are designed to minimize damage or loss to equipment caused by destructive arcing ground faults. This GFM system is designed for all polyphase applications and is ideally suited for motor control, motor control centers, and high voltage starters. Systems can be wye or delta, grounded or resistance grounded. When the ground fault current exceeds a preselected condition (current only, or current and time settings) the relay trips. The relay contacts can be connected in the control circuit of a motor starter, to the shunt trip of a circuit breaker or similar disconnecting or alarm devices. The system has an inverse time characteristic to prevent nuisance tripping.
The relay tripping current value is field adjustable over the trip current range of the sensor. The adjustable trip time delay relay, when specified, is field settable up to 36 cycles.

(Cover removed)
Where it’s essential to monitor performance or diagnose faults, a 300-Line starter may be ordered with an additional isolated, high-fidelity, normally-open contact on the overload relay. This contact may be used for direct input to a programmable controller or direct interface with a computer.
All line and load terminals on NEMA Size 00, 0 and
1 starters have saddle clamps to accommodate all types of terminations– ring, spade and strippedwire. Terminal numbering is permanently stamped, and terminals are staggered to help prevent shorting. NEMA
Size 2, 3 and 4 starters are also available with provision for ring terminations with staggered terminals. Size 5 starters are available with provision for ring terminations. In-line terminals for spade and stripped-wire connections are standard.
On NEMA Size 1 starters and larger, contact tips are weldresistant with cool operation and extended life. The contacts have a wedge-shaped configuration for positive make with minimum bounce. They can be easily changed from normally open to normally closed without additional parts on Sizes 0 and 1.
Magnet provides long life and is specially treated to resist rust.
The overload relay can be manually tripped deliberately as a convenient way to check against contact welding. Depressing the manual weld check arm trips the relay.
Then a welded contact can be detected with a simple continuity check.
Components
Overriding is eliminated because overload reset occurs only when the reset arm is released on the standard manual-reset form.
A bright yellow visual trip indicator tells operators at a glance if the overload has tripped. An optional automatic-reset overload relay is available for special applications upon request.
Overload relay heaters are completely interchangeable with heaters for 200- and 100-Line starters, eliminating the need to stock different heaters.
Relay trip points are factory calibrated at given currents for high accuracy. For added flexibility, the trip current of the relay is protection to any given motor and to eliminate nuisance tripping. A single calibration adjusts all three legs. The overload relay is available in standard or ambient-compensated forms.
Each auxiliary contact is rated 10 amperes AC, continuous current
(NEMA A600), and is suitable for either right or left side mounting. All necessary parts are supplied in the modification kit for easy installation.
An insulating shield is also provided for use between each auxiliary contact unit and the starter.
Auxiliary contact kits offered include one with a basic contact block and one with an adder block. The basic block is supplied with either a single circuit (one normally open contact or one normally closed contact) or a double circuit (one normally open and one normally closed contact). The adder block must be used in conjunction with a basic block. It may be ordered with either one normally open or one normally closed contact.

Solid-State Motor Winding Heater
Description
The motor winding heater is designed for use with 3-phase ac motors to guard against damage caused by condensation buildup on motor windings, which can occur in high-humidity environments during motor idle periods. With the heater connected as indicated in the connection diagram, and the motor not running, an SCR controlled current flows in the motor windings, producing enough heat to maintain the temperature inside the motor above the ambient temperature. The motor winding heater is automatically energized after the starter contacts (M) open, and de-energized when the starter contacts close. Fuses are included for SCR overcurrent protection and protection for wiring.
If desired, a pilot light can be connected as shown (“Fuse
Condition Indicator”) to visually monitor the condition of the fuses. With the starter contacts open, the light will be On if current paths through FU1 and FU2 are complete. The pilot light should have a line voltage rating.

Power Leader PQM
Description
The PQM is an ideal choice when continuous monitoring of a three phase system is required. It provides metering for current, voltage, real and reactive power, energy use, cost of power, power factor and frequency. Programmable setpoints and 4 assignable output relays allow control functions to be added for specific applications. This includes basic alarm on over/under current or voltage, unbalance, demand based load shedding and capacitor power factor correction control. More complex control is possible using the 4 switch inputs which also can be used for status such as breaker open/closed,flow information etc.
The PQM may be used as a data gathering device for a plant automation system that integrates process, instrument and electrical requirements. All monitored values are available via two digital RS485 communication ports running the Modbus protocol. If analog values are required for direct interface to a PLC, any of the monitored values can be output to one of 4 isolated analog outputs. A process variable can be measured using an analog input. A front panel RS232 communication port can be connected to a PC for simultaneous access of information by other plant personnel.
The quality of the power system is important with increasing use of electronic loads such as computers, ballasts or variable frequency drives. With the PQM’s power analysis, any phase current or voltage can be displayed and the harmonic content calculated. By knowing the harmonic distribution, action can be taken to prevent overheated transformers, motors, capacitors, neutral wires and nuisance breaker trips. Redistribution of system loading can also be determined. Waveform and chart recorder printouts available from the PQM assist in problem diagnosis.
Applications
• Metering of distribution feeders, transformers, generators, capacitor banks and motors
• Medium and low voltage systems
• Commercial, industrial, utility
• Flexible control for demand load shedding, power factor, etc.

Standard Features
• Phase unbalance: 12% (6% recommended for motor load protection)
• Phase loss protection
• Adjustable Trip Delay: 1 to 10 seconds after failure occurs
• Automatic Reset to Normal: upon removal of fault conditions
• Output Relay: nomally de-energized, form C contacts
• Electro-mechanical fault indicator: manually reset
• Status Indicator: bi-colored LED
Green: Output relay de-energized (normal state)
Red: Output relay energized (fault condition)
Dark: Loss of power
Optional Features
• Phase Reversal Protection: operates output relay instantaneously, has LED indicator
• Phase Sequence Protection: (same as phase reversal)
• Overvoltage and Undervoltage Protection: output relay de-energizes after preset time delay, if system voltage is over 115% or under 80%. (reset values are 107% and
90% respectively)
• Phase Unbalance: 6% (recommended for motor loads)

High-Resistance Grounding Unit
Where to Use
The function of high-resistance grounding equipment is:
1. To provide a ground for neutral of an ungrounded threephase power system, utilizing the high-resistance method.
Using this equipment allows the system to operate basically as an ungrounded system. The equipment is designed to eliminate the danger of high-transient overvoltages during certain types of ground faults.
Note: The use of high-resistance grounding on 600 volt maximum systems precludes line-to-neutral loading.
2. To provide an immediate warning when the first ground fault occurs through an alarm system.
3. To provide a method for quickly locating and removing the fault before another fault develops on another phase, thereby preventing circuit outages due to double line-toground faults. This is done by using the pulsing ground current feature and portable detector.
240, 480, or 600 Volt Systems
Equipment Range
Taps are provided on the standard DS9181 grounding resistor to adjust for a system charging current maximum of 3.56 amps or less. Since the normal charging current for most 600 volt or less systems is usually below one ampere, our standard equipment is adequate; however, for systems with greater charging currents refer to the Company for a quotation. Data for estimating the system charging current is shown in GEK-83750.

Standard Equipment Operation
The circuits used for low-voltage systems are shown in Fig. 1 and Fig. 2.
During normal conditions, with no ground fault on the system, only a small magnetizing current (capacitance-charging current) flows in the grounding transformers and no voltage appears across the resistor.
When a ground fault occurs, the resistor limits the ground current to a low value.
Taps are provided on the resistor to adjust the magnitude of the ground current in the range of 0.9 to 3.6 amperes, depending on the size of the system, so that the current supplied by the resistor to a ground fault will be slightly greater than the system’s natural capacitance-charging current.
The voltage appearing across the resistor will be sensed by the meter relay. Auxiliary contacts in the control, operated by the meter relay, are available for remote indication and annunciation of a ground.
A green indicating light on the equipment indicates that control voltage is available and that the system is normal. When a fault develops, a red indicating light on the equipment will light and remain lighted until the ground fault is removed. If no remote annunciator is available to notify the operator, an audible alarm may be added to the equipment as an option. A rotating red signal beacon can be used in noisy or remote installations.
To trace the ground fault, the operator turns the selector switch to the “pulse” position. This initiates cycle timing, alternately energizing and de-energizing a shorting contactor at the secondary resistor, resulting in a rhythmic fluctuation in the magnitude of the ground current.
The portable hook-on detector is then used to trace the fluctuations in ground current through the system to the point of fault.
After the ground point has been located and removed from the system, the operator then resets the selector switch to de-energize the pulse-cycle timing circuits.
The ground transformer for delta systems will consist of three single-phase transformers connected wye-delta. For wye systems, where system neutral is available, these grounding transformers are not needed.

Mag-Break Magnetic Circuit Breaker Trip Set Positions
The greatest degree of protection is provided when the magnetic trip setting is just above the motor starting inrush current. It is therefore recommended that the magnetic trip position be adjusted to a setting one position higher than the setting that carries the motor starting current. For recommended continuouscurrent ratings, see overload heater tables on pages J-7 through
J-15.

Thermal Magnetic Trip Ratings for Motor Circuits
These selections are based on 1999 National Electric Code requirements for squirrel-cage motors without code letters or with code letter through G. Lower trip ratings may be required for motor with code letter A and higher trips for motors with code letters H to V. Local code or specific application requirements may necessitate special selection. Thermal-magnetic circuit breaker combination motor control units are not recommended for motors with full-load currents of 3.8 amperes or less.

For continuous rated motors with a service factor of 1.15 to
1.25, select heaters from the heater table. For continuous rated motors with a service factor of 1.0, multiply the motor full-load current by 0.9 and use this value to select heaters.
Overload relay tripping current in 40°C ambient is the minimum value of full load current multiplied by 1.25.
WARNING: Overload relays with automatic reset may automatically start a motor connected to a 2-wire control circuit.
When automatic restarting is not desired, use a 3-wire control circuit.
Provide short circuit protection in accordance with the National
Electrical Code.

Overload Heater Tables
Heaters for Mag-Break Controllers
The Mag-Break protector is factory adjusted to the minimum trip setting.
WARNING:
To maintain overload, short circuit, and ground fault protection, use the following instructions to select heaters and to adjust the Mag-Break trip setting.
For continuous rated motors with a service factor of 1.15 to
1.25, select heaters from the heater table. For continuous rated motors with a service factor of 1.0, multiply motor full-load current by 0.9 and use this value to select heaters.
Use the heater table to verify that the Mag-Break and current limiter rating is correct for the motor full-load current. Then set the Mag-Break trip setting to the recommended value.
If the Mag-Break trips when starting the motor, increase trip setting one step at a time until the motor can be consistently started.

Do not exceed the maximum trip setting shown in the heater table.
Overload relay tripping current in 40°C ambient is the minimum value of heater full-load current multiplied by 1.25.
WARNING: Overload relays with automatic reset may automatically start a motor connected to a 2-wire control circuit.
When automatic restarting is not desired, use a 3-wire control circuit.
WARNING: Tripping of the Mag-Break may be an indication that a fault current has been interrupted. To provide continued protection against fire or shock hazard, all current-carrying parts and other components of the motor controller should be examined and be replaced if damaged. If heater burnout occurs, the complete overload relay must be replaced.

The Mag-Break protector is factory adjusted to the minimum trip setting.
For continuous rated motors with a service factor of 1.15 to
1.25, select heaters from the heater table. For continuous rated motors with a service factor of 1.0, multiply the motor full-load current by 0.9 and use this value to select heaters.
Overload relay tripping current in 40°C ambient is the minimum value of full-load current multiplied by 1.25.
WARNING: Overload relays with automatic reset may automatically start a motor connected to a 2-wire control circuit.

Heat Loss Considerations
In determining the heat loss of a motor control center for air conditioning requirements, 250 watts per foot of lineup is a reasonable assumption.
Actual heat loss will vary due to section loading and diversity factors. A typical motor control center may operate normally at
60 percent of maximum possible loading.
Fully rated circuit breaker starters with CPT’s, approximate losses are:
Size 1– 27 Watts
Size 2– 57 Watts
Size 3–130 Watts
Size 4–200 Watts
Size 5–300 Watts
Size 6–650 Watts
Heat losses for feeders and mains vary depending on frame size, loading and type of trip with electronic trips having lower losses. The following table provides a general guide for estimating losses assuming 80 percent loading. For critical applications refer to the Company.

Application Data
Non-Motor Loads
When selecting contactors for non-motor loads, the following load characteristics should be considered:
1. Voltage and maximum continuous current.
2. Maximum peak inrush current and duration.
3. RMS current and duration of maximum current on cyclic loads.
4. Frequency of operation.
5. Maximum interrupting current, voltage, power factor and wave form.
6. Available short-circuit current.
Non-motor load ratings are based on the use of two poles to control single-phase loads and three poles to control threephase loads.
Capacitor switching, requires special considerations. A discharged capacitor acts essentially like a short circuit, and the inrush current is limited by the impedance connected in series with the capacitor which includes connecting cables. Therefore, the maximum capacitance which can be switched by a contactor will increase with higher series impedance. Switching more than one capacitor or capacitor bank in close electrical proximity to each other should be avoided as the energized capacitor bank can increase the inrush current to the second bank when it is energized. Reactors or resistors may be required between the two capacitor banks to limit inrush currents.
NEMA Standards require shunt capacitors to operate satisfactorily at 135 percent of rated KVAR due to manufacturing tolerances and other variations. The higher inrush and steady state currents associated with these capacitors should be taken into consideration.
NEMA Publication ICS2-210 covers non-motor loads.

Motor horsepower output may also be calculated as follows:
HP = V x A x Pf x EFF
746
Rules of Thumb (Approximation)
At 1800 RPM, a motor develops a 3 lb. – ft. per HP.
At 1200 RPM, a motor develops 4.5 lb – ft. per HP.
At 460 volts, a 3-phase motor draws 1.25 amp per HP.
At 230 volts, a 3-phase motor draws 2.5 amp per HP.

kVAR Calculation When Motor Operating
Characteristics are Known
If motor HP, full-load power factor (PF) and efficiency (eff) are known, its easy to calculate the correct kVAR necessary to improve PF to any value.
Example
: 75HP, 3600 RPN, NEMA B motor with full-load PF of 87% and eff. of
92% corrected to 95%PF
Original PF = .87 Cos: Tan: = .567
Desired PF = .95 = Cos: Tan: = .329
Difference = .238
KW = HPx.746 or 75x.746 = 62
Eff. .902
.238 X 62 = 14.8 kVAR (use 15 kVAR)
