Verify Operation
To verify operation, follow these steps.
1. Make sure the circuit breaker/bale is in the ‘ON’ position, push the
‘Trip’ button on the circuit breaker, and observe that the toggle on the
circuit breaker and the switch on the handle have moved to the tripped
position.
2. Attempt to move the handle from the tripped position to the ‘OFF’
position and back again to ‘ON’ to verify reset of the circuit breaker.
If the handle does not move to the ‘ON’ position, adjust the circuit
breaker position and retry the trip sequence.
Adjust Circuit Breaker Position
To adjust the circuit breaker position, follow these steps.
1. Loosen the two circuit breaker mounting screws.
2. Turn the adjustment screw on the top of the base assembly to the right
(clockwise) to move the circuit breaker higher in the unit.
Turn the adjustment screw on the top of the base assembly to the left to
lower the circuit breaker in the unit.
3. If optional external auxiliary contacts are used, after the external
contacts have been snapped on, adjust the auxiliary bracket until the bale
contacts the plunger on the front contact when in the ‘ON’ position and
tighten to 20 lb•in (2.25 N•m).
4. Tighten the two circuit breaker mounting screws to 10 lb•in
(1.13 N•m).
TIP The adjustment distance is limited. If you feel resistance when you turn the
adjustment screw (and you confirmed that you have already loosened the
circuit breaker mounting screws), you have reached the adjustment limit.
