摘要:
A method and apparatus for a circuit breaker having an arc fault detection circuit, a ground fault detection circuit, a signal indicative of an arc fault in a corresponding pole of the circuit breaker; and a trip mechanism including a pair of separable contacts. The trip mechanism is in operable communication with the ground fault detection circuitry so than in response to receiving the signal from the ground fault detection circuitry, the arc fault detection circuitry causes the ground fault detection circuitry to generate a trip signal causing the trip mechanism to separate the pair of separable contacts.

An apparatus and method for controlling the operation of a solenoid in a circuit breaker includes a control circuit configured to receive an activation signal in response to a predetermined condition. The control circuit, in response to said activation signal, provides a first energizing signal to the solenoid for a first predetermined period, and cuts off the first energizing signal for a second predetermined period. The control circuit further provides a second energizing signal to the solenoid for a third predetermined period.
