Automatic Voltage Protector for Three Phase Systems with Adjustable Settings 63A 380V Reset Function

The automatic over-voltage and under-voltage protector is suitable for three-phase AC 380V, 50/60Hz, with a rated working current of 63A or less. Its main feature is to instantly cut off the power supply when over-voltage or under-voltage conditions occur, protecting electrical equipment from damage. The protector automatically restores power when the circuit voltage returns to normal levels. Color: gray white Material: PC plastic Functions: 1. Over-voltage protection 2.
