Flux Shifter Adjustment
After the flux shifter has been installed, the following
adjustment must be made:
With the breaker upright in the CLOSED position, the gap
between the trip paddle and the flux shifter adjustment
screw, shown in Figure 25, should be
1 / 32 ". A 1 / 32 "-
diameter gage or drill rod (not provided) may help to
measure the gap.
If adjustment is necessary, OPEN the breaker, then use
a
1 / 4 " wrench or nut driver to turn the adjustment screw.
To eliminate play in the trip paddle, gently push on the
trip paddle while adjusting the screw.
WARNING: Be extremely careful when working on a
CLOSED breaker. DO NOT reach your hands into the
mechanism while adjusting the flux shifter.
Optional Test – The flux shifter may be tested by closing
the breaker and applying a 9 Vdc power source to the
flux shifter leads (the red wire is positive). The breaker
should trip.
