MOUNTING THE CIRCUIT BREAKER TO A
PANEL
The circuit breakers are designed to mount to a
panel made from 11 ga. (.12 in.) thick steel. If
the breaker must be mounted to a panel of
different thickness, contact Toshiba.
Panel cutout dimensions for the circuit breakers
are given in Fig. 12. One cutout size is used for
all breaker types.
To mount the circuit breaker, follow the steps
below:
1. Loosen the small screw (M5) on the closing
handle and remove the handle.
2. Remove the four front plate mounting bolts
(M8) from the circuit breaker (Fig. 9).
Remove the spacer washers between the
front plate and breaker and discard them
(make sure none are left inside the breaker),
3. Align the breaker with the cutout and
mounting holes on the panel to which it is to
be mounted (Fig. 10). Some breakers are
furnished with two hooks which may be used
to temporarily attach the breaker to the
panel.
4. Using the four M8 bolts removed in step 2,
fasten the breaker and its front plate to the
mounting panel (Fig. 11).
torque should be 120-150 kgf-cm (9-11 ft-lb).
5. Replace the closing handle removed in step
1 and the M5 screw. The screw should be
tightened to a torque of 40-50 kgf-cm (35-43
in-lb).
