Abstract: The invention discloses a circuit protection device with self fault detection function. The ground fault protection unit comprises a ground fault detection circuit, an AC power supply path and an electromagnetic drive circuit. The self fault detection unit comprises an automatic detection circuit and a control circuit. The control circuit starts periodically a self fault detection process, controls the automatic detection circuit to generate a ground fault current GFC to the ground fault protection unit, and detects the fault status signal from the electromagnetic drive circuit. Based on the fault status signal, operation situations of the ground fault protection unit can be determined. If a fault occurs, an emergency interruption signal is generated, and that activates the electromagnetic drive circuit to make the ground fault protection unit trip in emergency, and cut off the AC power supply on load and socket terminals, and thus the emergency protection function is achieved.
