  • Patent number: 9906014
    Abstract: A circuit protection device with self fault detection function comprises a ground fault protection unit and a self fault detection unit, the ground fault protection unit can achieve the ground fault detection and protection function for AC power source power circuit and electrical appliance. The self fault detection unit is provided with two delay circuits which can achieve the fault detection at an early stage of power-on and periodically fault detection function. The ground fault protection circuit and the self fault detection unit can operate in time sharing, and achieve self fault detection without interruption of power supply. The self fault detection unit and the ground fault protection unit are separated from high impedance. Any fault occurred on any element in the self fault detection unit may not impair the protection ability of the ground fault protection unit.
