HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
When the circuit breaker handle is locked in the (O) OFF position, always use a properly rated voltage
sensing device to confirm that power is off before working on equipment.
Failure to follow these instructions will result in death or serious injury.

in the I (ON) position does not disable the
circuit breaker. If an electrical fault is detected, the circuit breaker
trips. When the handle is unlocked, it moves to the

position. To return the circuit breaker to service, reset the circuit breaker.
