  • Circuit interrupter for interrupting an electric current during fault conditions
    Patent number: 11196242
    Abstract: A circuit interrupter for interrupting an electric current in an electrical line is disclosed. The circuit interrupter includes an electronic circuit for monitoring and detecting a breaker fault condition. The electronic circuit is connected to a semiconductor switch for energizing a solenoid to trip a circuit breaker. A winding of the solenoid is energized to trip the circuit breaker. The solenoid is configured to have 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 circuit condition in a part of the winding, the electronic circuit is configured to provide a trip signal to the circuit breaker using the other part of the winding.
