Abstract
A leakage current detection and interruption (LCDI) device includes a leakage current detection module, including a first and a second leakage current detection line and at least one resistive element and/or at least one semiconductor element, configured to detect a leakage current signal on the first or second current-carrying line and to generate a leakage fault signal in response to detecting the leakage current signal. The first and second leakage current detection lines are electrically insulated from each other, and respectively cover one of the first and second current-carrying lines. The at least one resistive element and/or semiconductor element is coupled in series between the first and second leakage current detection lines to form a current path for detecting an open circuit fault in the leakage current detection module. By detecting the fault in the first and second leakage current detection lines, the reliability of the LCDI device is improved.
