Abstract
Resettable circuit breakers having an independent trip mechanism and a reset lockout are provided. The trip mechanism operates independently of the fault protection operations, and the reset lockout prevents the resetting of the circuit breaker if the fault protection is non-operational or if an open neutral condition exists.
