SECTION 3. FRONT AND BACK
FRAME DISASSEMBLY

The installation of a ProTrip Conversion Kit in a GE AK-1-
50 breaker requires that the front and back frames be
disassembled. The following steps describe this
procedure.

1. Remove the breaker opening springs, shown in

Figure 1. Save them for reinstallation.

2. Remove the spring clip on the crossbar mechanism

pin, shown in Figure 2, and slide out the pin. Save
the pin and clip for reinstallation.

3. Remove and save the nuts and lock washers holding

the front and back frames together. Four are used on
manually operated breakers and six are used on
electrically operated breakers.

4. Lift the front frame straight up and off from the back

frame.

5. Place the back frame on its back on a suitable work

surface.
