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 numbered
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 views of the completed flux
shifter installation.
1. Locate the flux shifter mounting hole, shown in

Figure 5.

2. For LA Gold breaker install the new flux shifter

assembly as shown in fig 7. For La gold units,

the # 6 screw protruding from the back of the

flux shifter assembly will plug in to the

mounting hole A (Figure 5).and position lower

mounting hole of the assembly over mounting

hole B (Figure 5).

By using mounting spacer, Hex bolt and lock

washer (provided in hardware kit) secure flux

shifter assembly to breaker mechanism side

plate as shown in fig 7.

Note:
Before installing flux shifter assembly, loosen reset-

bushing screw as shown in figure7, so that reset

bushing’s position can be adjusted between breaker

reset link and breaker trip latch while unit is being

positioned for mounting.
3. For RL breakers install the flux shifter assembly

as shown in figure 6 for RL units. The #6 screw

protruding from the back of the flux shifter

assembly will plug in to mounting hole A (Figure

5). Before mounting flux shifter assembly ,

remove the mounting hardware (hex screw,

washer, lock washer) secured to RL mounting

plate and reinstall as shown in fig 6 after unit is

properly positioned over drilled out mounting

hole C.

Once unit is completely adjusted (Instructions to

adjust are in later section of this manual) ,

breaker reset spring is to be anchored as shown

in fig 6.

Note:
Before installing flux shifter assembly, loosen reset-

bushing screw as shown in figure 7, so that reset

bushing’s position can be adjusted between breaker

reset link and breaker latch while unit is being

positioned for mounting.

Flux Shifter Adjustment

1. Figure 4 (a)
With the breaker in the tripped and open position,

move reset bushing in to engagement with the

breaker-reset lever. Lock in this position (for RL

breakers, hold link down while moving up bushing

or else link will move). Remove set screw and nut

and dispose.

2. Figure 4 (b)

With breaker closed adjust trip screw on trip slide

to 0.015 gap as shown. Lock in position with

locking nut in this closed position check that

dimension (A) is greater than 0.170. Dimension A

is meant to be an initial check to insure that the

device is properly installed. It may vary slightly

from

breaker to

breaker.
