にしてなることを特徴とする過電流警報装置。 A current detection device installed on the secondary side of the breaker, a comparator that compares the output level of the current detection device with a preset reference value, and a microcomputer that processes the input signal from the comparator. It consists of a blinking drive device that repeats ON/OFF operations in response to an output signal from a microcomputer, and a lighting lamp that is blinked by the blinking drive device, and the output level of the current detection device compared by the comparator is set to the reference level. An overcurrent warning device characterized in that the lighting lamp repeatedly flashes when a value exceeds the current value.
