Three Phase Adjustable Over and Under Voltage Protector with Over Current Protection Automatic Recovery Protective Device 63A
A powerful and practical three-phase protector. With adjustable overvoltage and undervoltage protection function, flexible setup of protection threshold according to the actual demand on electricity. Moreover, it also has over-current protection to keep the circuit safe in all aspects. It can cut off the circuit in time, and can automatically restore the power supply after the fault is removed when the abnormal situation occurs. Rated current is 63A, suitable for the protection of various three-phase electrical equipment, also can help to the stable operation of the power system.
