Three-phase adjustable over-under voltage protector, TOVPD3, automatic recovery and multi-protection functions

1. The automatic over - voltage and under - voltage protector is suitable for three - phase AC 380V, 50/60Hz loads with a rated operating current of 63A and below. Its main feature is that when an over - voltage or under - voltage problem occurs in the circuit, the product can instantly cut off the power supply to protect electrical equipment from damage. In addition, when the circuit voltage returns to normal, the protector can automatically turn on the power supply. 2. Color: Off - white 3. Material: PC plastic 4. Functions: 1.
