Installing and Adjusting the Flux Shifter
Assembly
Use the following procedures to install and adjust
the new flux shifter assembly, shown in Figure 4.
Numbers in brackets in the text refer to the num-
bered parts in Figure 4. The breaker should still be
resting on its back from the previous procedure
(removing the old components).

Installing the Flux Shifter Assembly

Figures 6 and 7 show two views of the completed
flux shifter installation.
1. Check that the diameters of the two flux shifter
mounting holes, shown in Figure 5, are .30 inch.
If they are less than this size, drill them out to .30
inch.
2. Loosen the screw on the flux shifter reset link [2]
and move the link to the bottom of its slot.
3. Remove and save the nut, lock washer, and flat
washer from the two mounting studs [6] on the
mounting surface of the flux shifter assembly.
Leave the spacers in place, as they are necessary
to ensure proper alignment with the breaker reset
link [12].
4. Install the flux shifter assembly on the right side
of the breaker frame where the original flux
shifter (if present) was removed. The two mount-
ing studs should fit through the existing holes in
the frame, as shown in Figure 5. Secure the flux
shifter assembly to the frame with the flat
washer, lock washer, and nut removed in step 3.

Flux Shifter Adjustment

1. With the breaker in the open (reset) position,
depress the flux shifter reset arm [1] so that
dimension A is held at about 0.4 inch.
2. Move the flux shifter reset link [2] up to contact
the breaker reset link [12] and take up any travel
in the breaker link.
3. Tighten the screw on the flux shifter reset link [2]
to secure it in position. The flux shifter is now in
its reset position.
4. Check that there is clearance between the reset
pin [5] and the reset latch [4] with the breaker in
the OPEN (reset) position. When the breaker is
CLOSED, the flat of the reset pin [5] must rest
against the reset latch [4].
