Abstract
A ground fault circuit interrupter device includes a switch unit for controlling a power connection between input and output ends; a leakage protection unit including a leakage detection module, for generating a leakage fault signal upon detecting a leakage current signal, and a leakage drive module including a first coil, for driving the switch unit to disconnect the power connection in response to the leakage fault signal; a timing unit including a timing control module, for performing timing in response to a time duration setting signal and generating a timed trip signal after a first preset time duration elapses, a time duration setting module for sending the time duration setting signal to the timing control module, and a timing drive module including a second coil separate from the first coil, for driving the switch unit to disconnect the power connection in response to the timed trip signal.
