A202 60 Ampere 2, 3, 4 or 5 Pole Lighting Contactors
THE CONTACTORS Electrically-held or magnetically-latched A202lighting contactors when wired as shown in Figure 4 can control tungsten, fluorescent or metal-vapor lamp loads. Each contactor and its associated load should be protected against short circuits by a suitable branch circuit protective device selected In accordance with the National Electrical Code (NEC).
This industrial type control is designed to be installed operated, and maintained by adequately trained workmen. These instructions do not cover all details variations, or. combin.ations of the equipment, its storage, delivery, installation, check-out, safe operation, or maintenance. Care must be exercised to comply with local, state, and natlonal regulations, as well as safety practices, for this class of equipment.
INSTALLATION Wire with conductors rated 75°C. If conductors rated higher than 75°C are used, their size must be based on the ampacity values for 75°C conductors.

ELECTRICALLY-HELD CONT ACTORS Electrically-held Model J contactors are available with a single or dual voltage coil. When equipped with a single voltage coil, the contactor is wired as shown in Figure 4. A connection diagram for a dual voltage coil is shown in Figure 3. When supplied with a dual voltage coil, the motor controller is normally wired for the higher voltage connection. The wiring may be changed to the lower voltage connection by removing and reconnecting the jumpers as shown in Figure 3.
AUXILIARY CONTACTS - TYPE J A maximum of four auxiliary units can be installed in the recesses of each contactor. These may be mounted with the terminals in a right angle relationship to the power poles. Type J auxiliary contacts mount by means of a spring clip and retainer screw. To remove the unit rotate the retainer screw several times (counterclockwise) and then slide the auxiliary contact unit out of the recess.

SHORT-CIRCUIT RATINGS
Coil
A202 lighting contactors are suitable for use on a circuit capable of delivering not more than the current (rms symmetrical amperes) shown in circuits rated not more than the voltage shown in Table III.
Magnetically-latched contactors are equipped with coils designed for intermittent duty only. Faulty coil action can be caused by a defective coil, faulty J1C coil clearing auxiliary contact, or damaged control module. It is recommended that all three be replaced when the contactor will not pull in or drop out. If the coil is changed just to change control voltage rating, it is not necessary to change the auxiliary contact or control module.
MODEL DESIGNATIONS Electrically-held lighting contactors are Model J. Magneticallylatched contactors are Model L. Read the model designation from the contactor nameplate to select the proper replacement coil or contacts.
Theory of Operation Each contactor contains a permanent magnet built into its structure that will maintain the contactor in its energized state indefinitely without using control power. When energized, DC voltage is applied to produce a magnetic field that reinforces the polarity of the permanent magnet and the contactor closes. Immediately, the current to the coil is disconnected by the coil clearing auxiliary contact. In order to open the contactor, it is necessary to create a field through the OFF coil in the reverse direction to the permanent magnet. This momentarily cancels the magnetic attraction and the contactor drops out. Care should be taken when servicing that leads do not become changed from their factory installed terminals, or improper operation and possibly permanent damage to the contactor could result.
MAGNETICALLY-LATCHED CONTACTORS Each magnetically-latched contactor consists of four components: the contactor mechanism, the coil clearing auxiliary contact, the control module and the coil, all of which are pre-installed and prewired at the factory.
CAUTION: DO NOT APPLY AC VOLTAGE DIRECTLY TO THE COIL TERMINALS OF THIS DEVICE! THE PERMANENT MAGNET WILL BE DEMAGNETIZED AND THE RECTIFIER WILL BE DAMAGED IF ALTERNATING CURRENT OR WRONG POLARITY DIRECT CURRENT IS APPLIED DIRECTLY TO THE COIL. CAUTION: AVOID ATTEMPTING TO MECHANICALLY LATCH OR DELATCH THE CONTACTOR.

Installation - First Turn Off Power A magnetically-latched contactor can be used with either a momentary contact (normally-open) pushbutton or selector switch, or a maintained-contact interlocked pushbutton or selector switch, as shown in Figures 7 and 8. For separate control, wire per Figure 7. Apply AC voltage only to auxiliary contact terminals 2 and 3, and to control module terminal L2, as follows: Connect the ON lead from the pushbutton to terminal 3 on the coil clearing auxiliary contact located in the upper left-hand cavity of the contactor. Connect the OFF lead to terminal 2 on the auxiliary contact. Connect the control station common terminal 1 to one line of the source of separate control voltage. Connect the other side of the separate control voltage supply to the terminal labeled L2 on the control module located in the upper right-hand cavity of the contactor. For common control, refer to Figure 8 and wire as follows: Connect the ON lead from the pushbutton to terminal 3 of the auxiliary contact and connect the OFF lead from the pushbutton to terminal 2 of the auxiliary contact. Connect lead A (not provided) as shown between line L2 and terminal labeled L2 on the control module. Connect wire
