The invention provides a ground fault breaking device with reverse wiring protection function and circuit status detection function, which comprises a self-detecting control circuit. When the ground fault breaking device is in a disengaging state, the self-detecting control circuit periodically detects the state of the circuit, if a certain fault occurs, for instance, an element is broken in a creeping signal detection circuit and a trigger control signal can not be outputted, the self-detecting control circuit can generate a circuit control signal to control the circuit to stop working, thereby improving the safety protection performance.
