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 conversion kit to
remount the X relay in its existing position.
