General Information
General Information
Class 8502 Type S magnetic contactors are used
to switch heating loads, capacitors, transformers,
and electric motors where overload protection is
separately provided. Class 8502 contactors are
available in NEMA Sizes 00-7. Type S contactors
are designed for operation at 600 Volts, AC 50-60
Hertz.
Class 8536 Type S magnetic starters are used for
full voltage starting and stopping AC squirrel cage
motors. Motor overload protection is provided by
melting alloy type thermal overload relays. Class
8536 starters are available in NEMA Sizes 00-7.
Type S starters are designed for operation at 600
Volts AC, 50-60 Hertz.
Holding Circuit Contact
Holding Circuit Contact
A normally open holding circuit contact for three
wire control is provided on all contactors as
standard. Sizes 00-2 contactors use a Class 9999
SX11 auxiliary contact as the holding circuit
contact. Sizes 3-7 contactors use a Class 9999
SX6 auxiliary contact as the holding circuit
contact. See Class 9999 for the holding circuit
contact electrical ratings. On Size 00-1 single
phase contactors, a power pole is used as the
holding circuit contact and therefore has the same
rating as the power contacts.
A normally open holding circuit contact for three
wire control is provided on all contactors as
standard. Sizes 00-2 contactors use a Class 9999
SX11 auxiliary contact as the holding circuit
contact. Sizes 3-7 contactors use a Class 9999
SX6 auxiliary contact as the holding circuit
contact. See Class 9999 for the holding circuit
contact electrical ratings.

Selection – Class 8536
Types SB-SD with Auxiliary Load Terminals – Class 8536
3-Pole Polyphase — Three Thermal Units Required
It is sometimes desirable to use the capacitors in motor branch circuits to improve power factor. The Size
0-2 Type SB-SD starters listed included three auxiliary terminals to allow easy connection of power
factor correction capacitors. When capacitors are connected using these terminals, no adjustment on
the selection of thermal units is necessary.
These terminals are also available as a kit Class 9999 Type PFL for Type S NEMA Size 0, 1 and 2
Starters with Motor Logic overload relays. These terminals are available for connection of power factor
(PF) correction capacitors. These kits are sold separately and are not factory installed.

Tables and footnotes are taken from NEMA Standards.
j
Ratings shown are for applications requiring repeated interruptions of stalled motor current or repeated closing of high transient currents encountered in rapid motor reversal, involving more
than five openings or closings per minute and more than ten in a ten-minute period, such as plug-stop, plug-reverse or jogging duty. Ratings apply to single speed and multi-speed
controllers.
t
Per NEMA Standards paragraph ICS 2-321.20, the service-limit current represents the maximum ms current, in amperes, which the controller may be expected to carry for protracted periods
in normal service. At service-limit current ratings, temperature rises may exceed those obtained by testing the controller at its continuous current rating. The ultimate trip current of overcurrent (overload) relays or other motor protective devices shall not exceed the service-limit current ratings of the controller.
a FLUORESCENT LAMP LOADS – 300 VOLTS AND LESS – The characteristics of fluorescent lamps are such that it is not necessary to derate Class 8502 contactors below their normal
continuous current rating. Class 8903 contactors may also be used with fluorescent lamp loads. For controlling tungsten and infrared lamp loads, and resistance heating loads, Class 8903
ac lighting contactors are recommended. These contactors are specifically designed for such loads and are applied at their full rating as listed in the Class 8903 Section.
u
Ratings apply to contactors which are employed to switch the load at the utilization voltage of the heat producing element with a duty which requires continuous operation of not more than
five openings per minute. Class 8903 Types L and S lighting contactors are rated for resistance heating loads.
k
When discharged, a capacitor has essentially zero impedance. For repetitive switching by contactor, sufficient impedance should be connected in series to limit inrush current to not more
than 6 times the contactor rated continuous current. In many installations, the impedance of connecting conductors may be sufficient for this purpose. When switching to connect additional
banks, the banks already on the line may be charged and can supply additional available short-circuit current which should be considered when selecting the impedance to limit the current.
The ratings for capacitor switching above assume the following maximum available fault currents: NEMA Size 2-3: 5,000 A RMS Sym.; NEMA Size 4-5: 10,000 A RMS Sym.; NEMA Size
6-7: 18,000 A RMS Sym. If available fault current is greater than these values, connect sufficient impedance in series as noted in the previous paragraph.
f
See Page 16 regarding operation rates for Size 6 & 7.
The motor ratings in the above table are NEMA standard ratings and apply only when the code letter of the motor is the same as or occurs earlier in the alphabet than is shown in
the table below. Motors having code letters occurring later in the alphabet may require a larger controller. Consult local Square D field office.

Application Data – Class 8502, 8536
Size 6 Type SH and Size 7 Type SJ Contactors
and Starters
Size 6 Type SH and Size 7 Type SJ contactors and
starters have a DC coil operated by a solid state
rectifier circuit mounted on the device and
powered from an ac source. The Size 6 and 7 are
equipped as standard with a fused control circuit
transformer (Form F4T) rated 240/480-120 volts
60 hertz, 220/440-110 volts 50 hertz. The purpose
of this transformer is to provide an isolated 120
volts 60 hertz, 110 volts 50 hertz, supply for the
control circuit. Size 6 and 7 devices may be
ordered for other system voltages by specifying
the voltage and frequency desired.
Size 6 Starter 8536 SH
Operation Rates
Continuous operation rate: 3 operations/minute
maximum. Jogging or Plugging Duty: 15
operations/minute – 3 minutes maximum.
4. Standard controllers are wired for common
control and are not convertible for operation of
the control circuit from a separate source of
supply voltage. Controllers designated Form S
have special wiring designed for separate
control. They are furnished with an isolating
transformer, usually having a 120 volt primary
and 120 volt secondary, that must not be
bypassed. Form S controllers are not
convertible for operation on common control.
The tables below give the replacement
transformers for Type S Sizes 6 and 7 contactors
and starters. To change voltages on these
devices, coils are not changed, instead
transformers with the desired voltage are
changed.
Replacement Control Transformers for Type S
Size 6
Voltage
Class 9070 Type
Field conversion for other system voltages is
accomplished by one of the following methods,
NOT BY THE USUAL PRACTICE OF CHANGING
THE COIL:
Size 7 Starter 8536 SJ
1. If the factory wiring is indicated as being for
480 volts 60 hertz, 440 volts 50 hertz,
conversion to 240 volts 60 hertz, 220 volts 50
hertz, can be accomplished by reconnecting
the control transformer as illustrated on
instruction sheet supplied with the controller.
This is the same method that would be used
on Class 9070 control circuit transformers.
Conversion to any other voltage requires
replacement of the control transformer. For
other system voltages: i.e. 208, 277, 380, 600
volts, a new transformer with single voltage
primary must be selected from table at right.
Control transformer connections are
illustrated on the instruction sheet supplied
with the controller.
2. If the factory wiring is indicated as being for
any voltage other than 480 volts 60 hertz, 440
volts 50 hertz, conversion to any other voltage
requires replacement of the control
transformer. Refer to table at right.
3. The standard transformer supplied may be
used to power a maximum of five Class 9001
Type K illuminated operators powered with
transformer type light modules. When extra
capacity to power control relays or other
inductive loads is required, a second
transformer must be added. Extra capacity
can be purchased as Form F4T with additions
in 100 VA increments.

Auxiliary Contacts
A N.O. holding circuit contact and a N.C. auxiliary
contact are provided as standard. The holding
circuit contact may or may not be required for
either 3-wire or 2-wire control. Size 6 and 7
devices have an additional N.C. auxiliary contact
which is wired in the coil control circuit. DO NOT
USE THIS N.C. CONTACT FOR ANY OTHER
PURPOSE.

General Information
Class 8502 Type W non-reversing vacuum
contactors are a new addition to the Square D line
of contactors. These contactors are used to switch
capacitors, transformers and electric motors
where overload protection is separately provided.
Type W vacuum contactors are designed for
operation at 600 Volts, 50/60 Hertz.
File E78351
CCN NLDX2
LR75167, 75168
Class 3211-04
By design, these contactors are well suited to
heavy-duty applications in harsh environments.
The power contacts are sealed in ceramic tubes,
called vacuum interrupters or vacuum bottles,
where the air has been evacuated. Arc quenchers
are not required because any arc formed between
opening contacts is not sustained due to the
presence of the vacuum. The arc is extinguished
when the current crosses zero after the contacts
are opened, therefore the arc typically does not
survive more than one half cycle. There is one
vacuum interrupter or bottle per pole, therefore a
three pole contactor has three vacuum
interrupters or bottles. The power contacts are not
affected by ambient conditions or contamination.
This provides for long life and reliable operation in
harsh applications.
Termination Means
The Size 4 vacuum contactor is supplied with line
and load side lugst. The Size 5 and 6 vacuum
contactors are supplied without line and load side
lugs. Class 9999 Type LUW5 and LUW6 lug kits
are available for the Size 5 and 6 contactors.
These kits include six lugs and the necessary
mounting hardware.
Auxiliary Contacts
An auxiliary contact block, Class 9999 Type
WX11, with one normally-open contact and
normally-closed contact is used with the Size 4, 5
and 6 vacuum contactors.
Auxiliary Contact Units
Auxiliary contact units may be added in the field.
the table below shows the maximum number of
units that may be added to a given size contactor
(in addition to the coil auxiliary contact).

Class 8702 Type WF
Reversing Vacuum
Contactor
Additional auxiliary contact units may be added to
the Size 4 and 5 reversing contactors in the field.
A maximum of 2 units may be added to the Size 4;
a maximum of 1 unit may be added to the Size 5.
No additional units may be added to the Size 6,
however, 1 N.O. and 1 N.C. circuit are available on
each forward and reverse contactor for customer
use.
GENERAL INFORMATION
Class 8702 Type W reversing vacuum contactors
are a new addition to the Square D line of
contactors. These reversing contactors are used
to switch capacitors, transformers and electric
motors where overload protection is separately
provided. Type W reversing vacuum contactors
are designed for operation at 600 Volts, 50/60
Hertz.
By design, these contactors are well suited to
heavy-duty applications in harsh environments.
The power contacts are sealed in ceramic tubes,
called vacuum interrupters or vacuum bottles,
where the air has been evacuated. Arc quenchers
are not required because any arc formed between
opening contacts is not sustained due to the
presence of the vacuum. The arc is extinguished
when the current crosses zero after the contacts
are opened, therefore the arc typically does not
survive more than one half cycle. There is one
vacuum interrupter or bottle per pole, therefore a
three pole contactor has three vacuum
interrupters or bottles. The power contacts are not
affected by ambient conditions or contamination.
This provides for long life and reliable operation in
harsh applications.
Altitude
The reversing vacuum contactor is designed to
tolerate normal barometric pressure variances up
to 6600 feet above sea level. If the contactor is to
be used above 6600 feet above sea level, please
consult the factory.
Termination Means
The Size 4 reversing vacuum contactor is
supplied with line and load side lugs. The Size 5
and 6 reversing vacuum contactors are supplied
without line and load side lugs. Class 9999 Type
LUW5 and LUW6 lug kits are available for the Size
5 and 6 contactors. These kits include six lugs and
the necessary mounting hardware.
Auxiliary Contacts
An auxiliary contact block, Class 9999 Type
WX11, with one normally-open contact and
normally-closed contact is used with Size 4, 5 and
6 vacuum contactors.

• Consequent pole
• Separate winding
A separate winding motor has a winding for each speed while a consequent
pole motor has a winding for every two speeds (three speed motors have two
windings). The motor connections (and thus the types of controllers) for two
speed starters are exemplified by the schematic diagrams shown to the left.
Note that consequent pole two speed controllers involve a 5-pole and a
3-pole starter while separate winding controllers have two 3-pole starters.
• Constant horsepower
• Constant torque
• Variable torque
Typical applications for these different types of motors are shown below.
NOTE: For detailed information involving the technical aspects of flexibility of
the starters used in the multispeed controllers, see Classes 8702, 8736 and

Speed Selection
The speed of a squirrel cage motor is directly proportional to the power
supply frequency and inversely proportional to the number of poles in the
stator winding. With the frequency constant, motor speed is determined by
the number of poles.

General

Standard starters are not equipped with any special relays to require starting
at lowest speed, progressive acceleration or deceleration through each
speed, etc. However, when the type of motor or characteristics of the load
involved make certain starting or control sequences necessary, four types of
relays/timers are available to accomplish the required function.

This relay makes it necessary for the motor to be started at low speed before
any higher speed can be selected. Pressing any push button except the low
speed will not start the motor. This arrangement insures that the motor will
always start the load at low speed. The stop button must be pressed before
it is possible to change from a higher to a lower speed.

To Power Circuit
When the starter is equipped with Form R2 accelerating relays, the ultimate
speed is determined by the button which is pressed, but the starter will start
the motor at low speed and then automatically accelerate it through
successive steps until the selected speed is reached. Definite time intervals
must elapse between each speed change. Individual timing relays are
provided for each interval, and all are adjustable. The stop button must be
pressed before it is possible to change from a higher to a lower speed.

This is similar in action to Form R2 accelerating relays, except that they

If it is necessary to have an imposed time delay when transferring from the
forward to the reverse direction or reverse to forward, then Form R10 should
be included in the form designation of the reversing multispeed starters.
This provides up to a 60 second delay in the transfer of the direction of the
motor, and can help prevent damage which could result from plugging.

AC Two Speed Magnetic Starters
Line Voltage — with Melting Alloy Overload Relays – Class 8810
Line voltage type, ac two speed starters are designed to control reconnectable squirrel cage motors to
operate at two different constant speeds, depending upon their construction. The use of an automatic
starter and proper control station permits greater operating efficiency and offers protection to both motor
and machine against improper sequencing or too rapid speed change. Protection against motor
overload in each speed is provided by an overload relay block which accepts three (3) thermal units.

NEMA Type 4X hubs are included with each starter at no additional cost.
Combination features available – consult factory.
Vertically Arranged, Open Type, Two Speed Starters
Vertically arranged starters are used where width limitations prevent the use of the conventional
horizontally arranged device. Such starters may be used to advantage in threaded NEMA Type 7
explosion-proof enclosures, and in multi-motor panels in which other equipment within the enclosure
used limits the available width.
These starters have all the features of the standard horizontally arranged devices, but the two
contactors are in a vertical arrangement. These starters are offered in open type construction only.

Special Arrangements with Three Devices
Three Type S Contactors can be mechanically
interlocked so that only one contactor can be
energized at any one time. The mechanical
interlock, pictured in Figure 2, is an interference
(non-jamming) type locking at the beginning of the
stroke of any contactor.
Factory assembled units are listed in the table
below. Figures 1 and 2 show factory assembled
and wired devices. All contactors are both
electrically and mechanically interlocked. The
class and type numbers listed only cover the
contactor and/or starter mounting arrangement,
NEMA size of the devices, and the number of
poles. A power and control wiring diagram must
accompany each order. Additional electrical
interlocks are available factory (or field) installed
in the locations shown in Figure No. 2 and Table
No. 2, Page 52. 8810 starters are supplied with
melting alloy type thermal overload relays.

Three and Four Speed AC Magnetic Starters
Line Voltage — with Melting Alloy Overload Relays – Class 8811, 8812
Class 881 and 8812 line voltage starters are designed to control 3 and 4 speed motors, respectively.
The use of an automatic starter and proper control station permits greater efficiency. The addition of
compelling relays to a starter gives protection to both the motor and the machine against an improper
sequence or a too rapid change in speed. The motor is protected against excessive operating currents
by overload relay blocks (one for each motor speed) each of which accepts three (3) thermal units. While
the starters listed are for use with consequent pole motors only, separate winding motor starters are
also available upon request.

Thermal Units
Thermal units should be ordered separately. For selection of thermal units, refer to the Catalog Thermal
Unit Selection Index R Digest. All starters require the use of three (3) thermal units for each speed of
the motor. Do not use the horsepower rating(s) for selection. Use nameplate FLC’s (Full Load Currents)
from motor nameplate.

MECHANICAL INTERLOCK
General
Class 9999 Type SM-1
Mechanical Interlock For
Two Contactors
Horizontally Mounted
Type S contactors or starters can be mechanically
interlocked so that only one device will be
energized at a time. The mechanical interlock is
an interference (non-jamming) type, locking at the
beginning of the stroke of any starter or contactor.
Three unit mechanically interlocked contactors
and/or starters are also available for various
combinations of Sizes 0, 1 and 2.
Type S Sizes 3, 4, 5 and 6
Overload Relay Mounting Bracket
Mechanical interlock Types SM-1 through SM-10
for Sizes 00-2 devices use overload relay
mounting brackets to support the overload relay
portion of the starter.
Class 9999 Type SM-12
For Sizes 3 and 4
Horizontally Mounted
three pole contactors, a different version for four
or five pole contactors. When adding a power
pole to an existing three pole reversing
contactor, a new mechanical interlock must
also be installed.
Type S Sizes 00, 0, 1 and 2
The mechanical interlock is mounted on the
underside of the reversing baseplate. Two pins
extend from the mechanical interlock through
openings in the baseplate and engage the contact
carrier of each contactor. Two styles of
mechanical interlocks are used: one version for
The mechanical interlock is separate from the
mounting pan on Sizes 3-6. Cams on the
mechanical interlocks are operated by the contact
carrier of each contactor. The mechanical
interlock is attached to the underside of the two
contactors on Sizes 3 and 4; directly to the
mounting pan on sizes 5 and 6. Size 5 and 6
mechanical interlocks are sold only as a factory
assembly with the 8810 starter.
The mechanical interlock utilizes a special
baseplate and bracket that connects between the
armatures. This is sold only as a factory assembly
with the 8810 starter.
