Circuit breaker bell alarm accessory having optional reset and lockout function

摘要

A combination air circuit breaker bell alarm reset and lock-out accessory unit interacts with the circuit breaker closing system to prevent charging of the circuit breaker closing spring until and unless the bell alarm module has been manually reset in one option and allows automatic reset of the bell alarm module prior to charging of the closing spring in a further option. The orientation of the bell alarm module on the combination reset and lock-out accessory unit support plate determines the reset or lock-out option selection.
