Patent ID: 11005260

Abstract:
A leakage current detection and interruption (LCDI) device for power cord, and power connector and appliance employing the same. The LCDI device includes a switch module coupled on the power supply lines to control electrical connection between input and output ends of the device; a leakage current detection module including a leakage current detection line, for detecting a leakage current on the power supply lines and outputting a leakage current fault signal accordingly; a drive module, for driving the switch module to disconnect the electrical connection in response to the leakage current fault signal and/or an open circuit fault signal, the open circuit fault signal representing an open circuit condition of the leakage current detection line; and a test module including a test switch, coupled to the leakage current detection module, where the leakage current detection module outputs the leakage current fault signal when the test switch is closed.
