Abstract
An air circuit breaker bell alarm accessory interacts with the circuit breaker closing system to allow automatic resetting of the bell alarm module upon resetting of the circuit breaker operating mechanism. A lockout slide extends between the bell alarm module support and the bell alarm reset slide to automatically reset the bell alarm module prior to closing of the circuit breaker contacts.
