を接続することを特徴とする漏電遮断器。 When the switching element is turned on by the output from the secondary coil of the zero-phase current transformer whose primary coil is the load circuit including the power distribution board, the current is transmitted through the half-wave rectifier and the current-limiting resistor. In the earth leakage breaker, which turns on a power cutoff relay connected to the power supply distribution line, and cuts off the supply of power to the load circuit by turning off a normally closed contact of the relay, the relay and the switching element are connected to each other. An earth leakage breaker characterized by connecting a series circuit of a resistor and a smoothing capacitor in parallel with the series circuit of the resistor.
