Din Rail Adjustable AC 380V 3 Phase Over and Under Voltage Protector Relays Voltmeter Monitors Phase Sequence Failure Protection

STVP series SINOTIMER brand automatic over-voltage and under-voltage protector is suitable for 3 phase AC 380V, 50/60Hz, rated working current 40A or 50A or 63A or 80A or less loads.

Its main feature is when the circuit has over-voltage or under-voltage, 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.

3.Voltage display (separate ABC phase volt measurement)
4.Three-phase Volt unbalance protection
5.Phase Sequence protection (reverse phase protection)
6.Zero line break protection
7.Phase Failure protection
8.Over-voltage protection value adjustable
9.Over-voltage recovery value adjustable
10.Over-voltage protection action time adjustable
11.Under-voltage protection value adjustable
