Circuit breaker bell alarm accessory with lock-out |
摘要 |
An air circuit breaker bell alarm accessory interacts with the circuit breaker contact position indicator to provide local and remote indication of the occurrence of a circuit interruption. A drive pin extending from the bottom of the accessory interacts with a slot on the contact position indicator lever to prevent release of the circuit breaker closing spring until the bell alarm accessory is manually reset.
