Arc fault protector is a kind of switch cabinet, which can close, transmit and disconnect current under all normal ring road standards, and can close, transmit and disconnect current under abnormal ring road standards at a specific time. The arc fault protector is divided into high voltage arc fault protector and bottom voltage arc fault protector according to its application category. The difference between high voltage and low voltage is not clear. Generally, those above 5kV are called high-voltage electrical appliances. Arc fault protector can be used to distribute electromagnetic energy, run asynchronous motor infrequently, maintain cable and motor, etc., and automatically disconnect power circuit in case of serious load, short circuit fault and undervoltage protection fault.
