Abstract

A single circuit breaker housing containing a circuit breaker to disconnect the line terminal from the load terminal for a current overload and means to disconnect and reconnect the line terminal from the load terminal for power management. The power management means, activated by an internal or external timer or remote modulated signal, may include a switch in series with circuit breaker contacts or fusible element or electromechanical device to set and reset the circuit breaker contacts. The external timer or other remote activation signals are provided via external terminals on the housing or via a wireless or powerline modulated signal. Electro-optical isolator functionally interconnects and electrically isolates the power management means and the circuit breaker.
