Product Description
Three Phase AC 380V 400V 63A Multifunctional Over Under Voltage Protection Device Automatic Recovery Voltage Relay TOMZN brand 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. Functions: 1.Over-voltage protection 2.Under-voltage protection 3.Automatic recovery 4.Voltage display(voltage measurement) 5.Three-phase ampere unbalance protection 6.Phase sequence protection (reverse phase protection) 7.Zero line break protection 8.Phase failure protection Product Parameters: 1.Model number : TOVPD3 2.Power supply:3*230V / 400V AC 50/60Hz 3.Max.Loading power:63A
