Adjustable Over Under Voltage Protector, Compatible with Tomzn Three Phase, Automatic Recovery Protection Device

The automatic over-voltage and under-voltage protector is suitable for three-phase AC 380V, 50/60Hz, rated working current 63A or less loads. Its main feature is when the circuit has over-voltage or under-voltage problems, the product can cut off the power supply instantaneously to protect the electrical equipment from being damaged, besides,the protector can automatically turn on the power supply when the circuit voltage returns to the normal.
