Operator Handles for Circuit Breakers
In the event of a circuit breaker fault, the circuit breaker operator handle moves
to the TRIP/+ position. Only reset the circuit breaker after the cause of the fault
has been determined and corrected.
Follow these procedures to reset the circuit
breaker.
1. Turn the circuit breaker handle from
the TRIP/+ position to the OFF/O
position.
2. Turn the circuit breaker handle from
the OFF/O position to the RESET
position.
3. Locate and correct the fault.
4. Verify it is safe to re-energize the unit.
5. Turn the handle from the RESET position to the ON/I position.
Locking Units in the OFF/O Position
1. The large rotary-operator handle must be in the OFF/O position.
2. Pull the middle section of the operator handle toward you.
The lock opening is now visible.
3. Insert and secure the lock.
Up to three 8 mm locks can be inserted.
ATTENTION: Follow all company safety and lockout procedures, and local codes
when performing this procedure.
