  • Arc-default detecting circuit breaker system
    Patent number: 7035066
    Abstract: An arc-fault detecting circuit-breaker system is operable with a protected electrical circuit that operates with direct current or alternating current. A normally closed line circuit breaker has an electrical input and an electrical output, and an electrical line connects the electrical output to the protected-element input. The system includes a detector of the rate of change with time of a current flow in the electrical line. An activating element alternating current voltage source has an alternating current output. A circuit-breaker activating element is operable responsive to the detector. The circuit-breaker activating element is electrically connected between the electrical line and the alternating current output.
