ABSTRACT:
A combined bell alarm and lock-out accessory is connected with the electronic trip unit that controls a high ampere rated circuit breaker. The accessory interacts with the circuit breaker operating mechanism to activate the bell alarm upon circuit interruption and to prevent the closing of the circuit breaker contacts until the accessory is manually reset. The circuit breaker lock-out mechanism interfaces between the circuit breaker operating mechanism and the accessory to insure that the contacts remain open until the accessory is completely reset.
