GE AK-50 Front Frame Breaker Conversion, Relocating and Remounting the W and X Relays

SECTION 3. FRONT FRAME BREAKER CONVERSION

Front frame conversion consists of the following steps:

1.Separation of the front and back breaker frames for AK-50, AKU-50, AKS-50, and AKT-50 breakers. (Frame separation is not necessary for AK-75 and AK-100 breakers.) Refer to the appropriate installation and maintenance manuals supplied with the breakers and equipment for instructions on frame separation. Copies of these publications may be obtained from your local GE sales office.

2.Relocation and remounting the W and X relays on AK-50, AK-75, and AK-100 electrically operated breakers with EC trip devices.

3.Installation of the flux shifter assembly and trip paddle.

4.Installation of the trip unit mounting bracket.

5.Installation of the trip unit wiring harness.

Relocating and Remounting the W and X Relays

This step is necessary on electrically operated breakers with EC trip devices. Figure 1 illustrates this process. Figure 2 shows the new mounting brackets supplied with the kit.

1.Remove the W relay and install the mounting bracket supplied with the conversion kit to the upper left side of the frame

2.Remove the X relay and its mounting bracket. Use the new bracket supplied with the conver- sion kit to remount the X relay in its existing position.
