Ground fault circuit interrupter incorporating circuit breaker, shunt module and ground fault detection device

A ground fault circuit interrupter, comprising:

• a circuit breaker, configured to connect and disconnect an electrical connection between an input end and an output end of a plurality of power supply lines;
• a shunt module, coupled to the circuit breaker and configured to drive the circuit breaker to disconnect the electrical connection;
• a ground fault detection device, coupled to the shunt module, having a detector coil opening on its exterior housing configured to accommodate the power supply lines to pass through the detecor coil opening without entering the exterior housing of the ground fault detection device, wherein the ground fault detection device is configured to detect a ground fault signal on the output end of the power supply lines and to output a control signal to the shunt module in response to detecting the ground fault signal, wherein the shunt module is configured to drive the circuit breaker to disconnect the electrical connection in response to the control signal;
• and
• at least one fastening device configured to join the ground fault detection device and the circuit breaker to each other.
