Abstract
A leakage current detection and interruption device includes a switch module; a leakage current detection module for detecting leakage current signal on current carrying lines and generating a leakage fault signal in response thereto; a drive module, coupled to the switch module and the leakage current detection module, for driving the switch module to disconnect electrical connection on the current carrying lines in response to the leakage fault signal; a self-test module, coupled to the leakage current detection module and the drive module, for periodically generating a simulated leakage current signal and detecting malfunction in the leakage current detection module and/or drive module, and generating a self-test fault signal in response thereto; and an alarm module, coupled to the self-test module, for generating an alarm signal in response to the leakage fault signal and/or self-test fault signal. The device can alert the user under tripped or malfunction conditions.
