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.
