ABSTRACT:
An air circuit breaker bell alarm accessory interacts with the circuit breaker operating mechanism to provide local target indication as well as remote signal indication of the separation of the circuit breaker contacts. An indicator switch provides remote signal indication while a lock-out switch interacts with the accessory target to prevent re-closure of the circuit breaker contacts. One of the switches is selected having "normally open" contacts while the other switch is selected having "normally closed" contacts to reduce the amount of mechanical force required to simultaneously operate the indicator and lock-out switches.
