Installing the Flux Shifter
Figure 8 shows the unassembled flux shifter and its
mounting hardware. The flux shifter is mounted to the
right of the operating mechanism, as shown in Figure 9.
1. Remove the existing flux shifter device.
2. Mount the flux shifter trip paddle on the breaker’s trip
shaft as shown in Figures 9 and 10. Push the draw-
out locking lever in to allow the trip bar to rotate to an
accessible point.
3. Save the new actuating bushing for installation in the
right operating link in the back frame, as described in
Section 4.
4. Mount the flux shifter assembly to the right side of
the front frame, as shown in Figures 9 and 10. On
Power Sensor breakers equipped with a shunt trip,
mount the flux shifter on top of the shunt trip bracket.
If no shunt trip is installed, use the
1 / 8 -inch spacer
provided, as indicated in Figures 10 and 11. On EC-
equipped breakers, the mounting hole must be drilled
and tapped for a #10-32 screw.
