Abstract
A miniature circuit breaker incorporating ground fault protection and arc fault protection includes main separable contacts. An operating mechanism actuated by a trip mechanism opens the main separable contacts in response to predetermined current conditions. Auxiliary separable contacts are disposed in series with the main separable contacts. A solenoid having a movable plunger opens and closes the auxiliary separable contacts in response to a remote external signal. A ground fault trip circuit detects a ground fault, and an arc fault trip circuit detects an arc fault. An actuator mechanism, energizable by the ground fault trip circuit and the arc fault trip circuit, actuates the plunger to open the auxiliary separable contacts.
