Ground fault circuit interrupter device and related electrical connection devices and electrical appliances

A ground fault circuit interrupter device, comprising:

• a switch unit, coupled between an input end and an output end of current carrying lines, configured to control a power connection between the input end and the output end;
• a leakage protection unit, comprising:
• a leakage detection module, configured to detect a leakage current signal on the current carrying lines, and to generate a leakage fault signal in response to detecting the leakage current;
• and
• a leakage drive module, coupled to the switch unit and the leakage detection module, configured to drive the switch unit to disconnect the power connection in response to the leakage fault signal, wherein the leakage drive module includes a first coil;
• and
• a timing unit, comprising:
• a timing control module, configured to perform timing in response to a timing condition setting signal, and to generate a timed trip signal when a first timing condition specified in the timing condition setting signal is met;
• a time duration setting module, coupled to the timing control module, configured to transmit the timing condition setting signal to the timing control module;
• and
• a timing drive module, which is separate from the leakage drive module and is coupled to the timing control module and the switch unit, and configured to drive the switch unit to disconnect the power connection in response to the timed trip signal, wherein the timing drive module includes a second coil which is separate from the first coil.
