Abstract
A circuit interrupter () for interrupting an electric current in an electrical line is disclosed. The circuit interrupter () includes a controller () for detecting a breaker fault condition. The controller () is connected to a first semiconductor switch () for energizing a solenoid () to trip a circuit breaker on detection of the breaker fault condition, wherein a winding of the solenoid () is energized to trip the circuit breaker, and wherein the solenoid () is configured with a center tap in the winding, such that there are two parts () in the winding separated by the center tap. Further, upon detection of an open condition in a part of the winding, the controller () is configured to provide a trip signal to the circuit breaker using the other part of the winding.
