Abstract

A leakage current detection and interruption device includes a switch module for connecting and disconnecting an electrical connection between input and output ends of current carrying lines; a leakage current detection module coupled to the current carrying lines, for detecting a leakage current signal on the current carrying lines and generating a detected signal in response thereto; a leakage current processing module coupled to the leakage current detection module, for receiving the detected signal and generating a leakage fault signal based on the amplitude and frequency of the detected signal; and a drive module coupled to the switch module and the leakage current processing module, for receiving the leakage fault signal and driving the switch module to disconnect the electrical connection in response thereto.
