THE EARTH LEAKAGE CIRCUIT BREAKER WITH CIRCUIT BREAKER MONITORED POWER SUPPLY STATE

摘要

PURPOSE: A panel board is provided to monitor the state of a power supply process and a wire in a remote place by transmitting a signal which is converted and analyzed in a main board through a communications board in a remote place. CONSTITUTION: A circuit breaker(100) functions as a plurality of branch breakers including an electric leakage detecting function. The circuit breaker includes an electric leakage detecting board which detects leakages through an internal zero-phase current transformer. A holder(200) supports the circuit breaker. A main board(300) is connected to the circuit breaker and receives a signal. A communications board(400) outputs the signal that is converted and analyzed through the main board to the outside.
