Lighting Control

Class 8903 – Combination Lighting Contactors, Type S

Features

The features include: disconnect switch and circuit breaker versions; rugged flange-mounted handle; easy installation; occupation of less space; increased operator protection; room to spare for modifications; Class R fuse clips standard; electrically and mechanically held; 30–600 Amperes.

It is desirable to install the branch-circuit protective device and lighting contactor, combining switching and over-current protection, in one enclosure.

Combination lighting contactors are well suited for industrial, highway and area lighting applications, or where a lighting circuit may have to be disconnected for periodic maintenance. They may also be used for resistance heating loads.

NIGHT-MASTER Combination Lighting Contactors

The Class 8903 NIGHT-MASTER Outdoor Combination Lighting Contactor is the only product on the market that is UL

Listed for Service Entrance. This allows the contactor to be pole mounted when used to control lighting in remote locations such as parks, monuments, group sports facilities, and streets and highways.

Factory modifications such as photocells, time switches, key operated selector switches, and the combination of photocells and time switches (photocell on, time switch off) allow the NIGHT-MASTER to be located in applications where manual operation of lights is not practical.

NIGHT-MASTER comes in long and short versions in sizes 30 through 200 Amperes. Most common modifications can be provided from the factory, or added in the field to pre-drilled and pre-tapped panels.

Lighting Control

Class 8903 – Panelboard Lighting Contactors, Type PB

General Information

Panelboard Lighting Contactors, sometimes called remote control switches, are designed for use with lighting panelboards and motor control centers where either panel or bus mounting is desirable. Type PB lighting contactors can be used in a retrofit or new project without increasing the panelboard depth. They can be used to directly replace many inoperative existing switches.

The features include: mechanically held; compatible with Square D panelboards; short-circuit ratings to 100 KA; compact arc suppression; bus or panel mounted; fits in standard-depth lighting panelboards; easy manual operation; standard coil clearing contacts; and the ability to operate in any position.

For electrically-held enclosed devices, the first pilot is wired in parallel with the coil. Operating interlocks are required for all additional pilot lights.

Mechanically held devices require operating interlocks for all pilot lights.

Electrically held 20 Amp multipole contactors cannot add interlocks. Additional poles can be used for the same function, however. Mechanically held

(Type LX) provide one double throw auxiliary (or status) contact as standard.

Order Example

You have previously selected a Class 8903SMG2V02. V02 means that you need a coil voltage of 120-60/110-50 wired for separate control. You would like to add form FF4T with the transformer voltages being 480 volt primary, 120 volt secondary.

Application of Lighting Contactors

Lighting contactors have evolved from the need for more than just simple on-off manual control of lights.

Today’s requirements call for the development of new and varied types of control. Often the application will call for remote control of lighting from some distant location. This control may or may not be in addition to a master control station at a central location. Certain applications include the use of automatic control by time clocks or photelectric cells. Whatever the need may be, applications are increasing, and lighting contactors are designed to meet the ever-changing requirements.

Square D lighting contactors offer a time-proven design for better electrical and mechanical performance. They are used wherever reliable, convenient and economical control of indoor and outdoor lighting is required. Typical installations include:

• parking lots

• industrial plants

• office buldings

• theaters and auditoriums

• hospitals and institutions

• shopping centers

• stadiums

• airports

Tungsten Lamp Loads

Tungsten lamps have a positive resistance characteristic (resistance to the flow of electric current increases as its operating temperature increases), thus exhibiting an increase in resistance when the lamp is energized. Therefore, these lamps have a high inrush current of up to 18 times normal current resulting from the low cold resistance of the tungsten. Examples of tungsten lamps include incandescent lamps, iodine lamps, quartz-iodine lamps and infrared lamps.

Ballast Lighting Loads

A ballast lighting load consists of electric discharge

(vapor) lamps. All types of vapor lamps possess a negative resistance characteristic. The resistance within the lamp decreases with an increase in current and vice-versa. Without some form of current limiting device in the electric circuit, the current would rise quickly until lamp failure occured. This current limiting element is known as the ballast. A ballast is an impedance used to stabilize the current in a vapor lamp.

It has the property of increasing in resistance as current through it increases and decreasing in resistance as current decreases. Thus it tends to maintain a constant current through it. Types of ballast lighting include high intensisty discharge (HID) lamps – mercury vapor, metal halide and high pressure sodium – and flourescent lamps.

Resistance Loads

Square D lighting contactors are fully rated for resistance loads up to 600 volts. They can be used on resistance-type boilers, electric furnaces, electric water heaters and snow melting cables and panels.

Lighting Control

Application Data – Class 8903

Motor Loads

These loads consist of motors having an inrush current, or locked-rotor current, of approximately six times the full-load current. Square D Type S lighting contactors are fully rated for motor loads and have a horsepower rating equal to the equivalent NEMA-Size motor contactor.

Lighting Contactors for Energy Management

Lighting contactors should be an integral part of any

Energy Management System. They help conserve energy consumption and reduce utility bills by providing three types of control.

Lighting contactors offer both centralized and remote control of lighting. Cirucits can be turned on and off from a number of remote locations in addition to a master control station.

They also offer selective switching of lights.

Selective switching is the control of one or more individual lighting circuits, independent of the other circuits. This design allows the potential for turning on only the amount of lighting that is actually needed.

Lighting contactors can provide automatic control to insure that lights will be turned off when not needed.

There are a number of devices that, when used with lighting contactors, offer a convenient and reliable method of automatically controlling lighting loads: program time clock, photoelectric cell, programmable controller and demand controller.

Installation of Lighting Contactors

For new installations, lighting contactors can either be installed right in the lighting panelboard, or in their own enclosure next to or remote from the panelboard.

In existing applications where the lighting control system is being updated, lighting contactors can be installed in their own enclosure next to a lighting panelboard.

Compression Lugs

Square D Versa-Crimp

compression lugs for Type S lighting contactors,

100–800 ampers, are available factory installed (Form Y157-4) or as a field modification kit (see table on page 9).

They are suitable for both copper and aluminum wire.

One VCEL lug (one or two on the

400 and 600 amperes devices) is required for each line or load terminal.

Each Class 9999 Type AL hardware kit includes mounting hardware for 3 terminals, line or load side.

EXAMPLE: To install compression lugs on a 300 ampere 3 pole device, line and load sides, order six (6)

VCEL-060-12H1 lugs and two (2)

Class 9999 Type AL11 hardware kits.

Class 8903 – Application Data

Maximum Voltage Rating

When selecting lighting contactors, the maximum voltage rating of the device must be considered in addition to its current rating. The table below lists the maximum ac voltage ratings of the Types L and S lighting contactors for ballast, tungsten and resistance loads. Lighting contactors also have dc ratings which are shown below.

Current Ratings

All Class 8903 lighting contactors are fully rated for tungsten, ballast and resistance loads. This means that a contactor can be used to control a load up to its full nameplate rating. Derating of the contactor is not necessary, as is the standard practice with circuit breakers and fuses.
