GROUND FAULT INTERRUPTER |
摘要 |
A malfunction of a ground fault interrupter due to a lightning surge is prevented, and a power source short circuit caused by a short-circuit damage of an arrester due to a high-level lightning surge is prevented. A contact (41), an overcurrent sensing section (43), and a zero-phase current transformer (44) are arranged in this order from the power source side toward the load, and the arrester (3) is connected between the overcurrent sensing section (43) and the zero-phase current transformer (44).
