3–3 Shunt Trip Device
The shunt trip, shown in Figure 22, allows the breaker to
be tripped electrically from a remote location. A cut-off
switch is supplied as part of the shunt trip to automatically
remove power from the shunt trip coil when the breaker is
tripped. The electrical characteristics of the shunt trip are
listed in Table 5. Figure 23 is the shunt trip wiring dia-
gram.

Mounting Plate Removal
The mounting plate is used as the anchor position for the
shunt trip, blown-fuse trip, and undervoltage release
accessories. Breakers are shipped from the factory with
either a mounting plate or an L-shaped bracket to retain
the molded-plastic crank. A new mounting plate is pro-
vided in the shunt trip kit, blown-fuse trip kit, undervol-
tage release kit, and auxiliary switch kit.
• If the breaker was supplied with an L-shaped bracket,
remove the two retaining screws, discard the bracket,
and skip to the appropriate installation instructions.
• If the breaker was supplied with a mounting plate,
remove it with the following procedure:
