GROUND FAULT CIRCUIT INTERRUPTING DEVICE WITH IMPROVED THYRISTOR TRIGGERING

摘要

41PR-6162 GROUND FAULT CIRCUIT INTERRUPTING DEVICE WITH IMPROVED THYRISTOR TRIGGERING A fault signal integrating capacitor and a comparator responsive to an integrated fault signal voltage are connected in feedback circuit fashion such as to provide for the generation of a succession of thyristor gate triggering pulses to insure reliable current activation of a trip solenoid acting to effect separation of circuit interrupting contacts.
