Instructions for Class A202 100 or 200 Ampere 2,3,4 or 5 Pole Lighting Contactors
INSTALLATION
THE CONTACTORS Electrically-held or magnetically-latched Class A202 lighting 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). See Tables IV and V.
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 combinations of the equipment, its storage, delivery, installation, check-out, safe operation, or maintenance. Care must be exercised to comply with local, state, and national regulations, as well as safety practices, for this class of equipment. 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. Where only three poles of a five-pole lighting contactor are to be used, it is recommended that the three poles selected be the three center poles.

ELECTRICALLY-HELD CONTACTORS Electrically-held Model M 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 contactor 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. ELECTRICALLY-HELD COIL DATA (TYPICAL VALUES) Contactor

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.
Coil Magnetically-latched contactors are equipped with coils designed for intermittent duty only. Faulty coil action can be caused by a defective coil, faulty J1C cot/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. See Table III.
Theory of Operation Each latch 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 coilclearing 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 latch 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 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 coil-clearing 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 coil-clearing auxiliary contact and connect the OFF lead from the pushbutton to terminal 2 of the coil-clearing auxiliary contact. Connect lead A (not provided) as shown between line L2 and terminal labeled L2 on the control module. Connect wire from control station common terminal 1 to line L1.

AUXILIARY CONTACTS - TYPE J A maximum of four auxiliary units can be installed in the recesses of each electrically-held contactor. A magnetically-latched contactor can accommodate two. 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.
MAINTENANCE - First Turn Off Power 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 combinations of the equipment, its storage, delivery, installation, check-out, safe operation, or maintenance. Care must be exercised to comply with local, state, and national regulations, as well as safety practices, for this class of equipment.
Failure to completely disconnect the motor controller from all communications networks and power sources, including control circuit power, prior to installation, maintenance or inspection may result in severe injury or death.

To Replace The Coil
To Inspect Contacts
Refer to Figure 9. Loosen the assembly screws (11) located to the immediate left and right of the arc box. Pull the loosened upper base structure (12) forward. Pull the coil (13) from the upper base structure and check the auxiliary contacts for secureness when repositioning the upper base. Tighten the assembly screws. Refer to Table VIII.
Refer to Figure 9. Loosen the two arc box assembly screws (1) located immediately above and below the nameplate and remove the arc box (8). Contacts (5) are visible. Retighten the screws per Table VIII. To Replace Contacts After removing the arc box, compress the overtravel spring (7) and remove the spring retainer clip (9) and the moving contact (5) from the crossbar (6). Remove the retaining screws (3) and lift out the stationary contact assembly (10). To replace contacts, reverse the above procedure, making sure that stationary contacts are secure (see Table VIII), and that the extrusion on the spring retainer clip engages the hole in the moving contact. Make sure that the moving contacts are free to move, overtravel springs are seated, and the crossbar moves freely when the arc box is in position. The silver cadmium oxide contact buttons need NO dressing or lubricant throughout their life.
Magnet - Armature Assembly Self-alignment and permanent air gap features of the magnet armature make replacement unnecessary. Mating pole face surfaces should be kept clean. Arc box must be in place when the contactor interrupts a circuit.
Important - Replace all contacts and springs as a group to avoid misalignment. Eaton Corporation Electrical Sector 1111 Superior Ave. Cleveland, OH 44114 United States 877-ETN-CARE (877-386-2273) Eaton.com © 2011 Eaton Corporation All Rights Reserved Publication No. IL17509 / 001 May 2011
