Abstract
An arc fault circuit breaker includes a housing, separable contacts, an operating mechanism adapted to open and close the separable contacts, and an arc fault trip mechanism cooperating with the operating mechanism to trip open the separable contacts. The arc fault trip mechanism includes an arc fault test circuit adapted to simulate an arc fault trip condition to trip open the separable contacts. A proximity sensor, such as a Hall effect sensor, is adapted to sense a magnetic target to actuate the arc fault test circuit.
