特徴とする電源用ブレーカ。 A digital switch that can be set to a desired current value in advance, a current detection circuit that detects the output current of the breaker body connected to the power supply circuit, and an A/D conversion circuit that digitally converts the detected current of the current detection circuit. It is characterized by comprising a comparison circuit that compares a set value of the digital switch and a detected current digital signal from an A/D conversion circuit, and an indicator light that is lit when the detected current digital signal value is larger than the set value. Breaker for power supply.
