Installing the Flux Shifter

1. Carefully rotate the breaker onto its back so that the

bottom of the breaker is accessible.

NOTE: If the breaker has already been converted to
solid state trip devices, the existing trip actuator and
linkage must be removed and discarded.

2. Remove and retain the left front rack mounting bolt

on the breaker frame. The head of the bolt has a
radial slot cut into it. Slide the new flux shifter
assembly in through the bottom of the breaker, as
shown in Figure 22 for 225–800 A breakers and in
Figure 23 for 1600 A breakers. Align the bracket with
the hole in the frame from which the mounting bolt
was removed. Reinsert the mounting bolt through the
hole in the frame.

3. On 225–800 A breakers, insert the

hole in the side of the breaker frame. Place the two
washers and the cotter pin provided on the other end
of the pin.

NOTE: If an auxiliary switch is mounted on the left side
of the breaker, the auxiliary switch operating arm must
be modified. Drill out the pin that is connected to the
crossbar arm with a 0.257"-diameter drill. Place the end
of the link over the pin inserted through the crossbar
arm and reset link. Use only one washer and the cotter
pin.
