Adjustable 3 Phases 4 Wires Voltage Protector, 220VAC 60Hz 80A Load, Low Consumption LCD Self-Recovery Over and Under Voltage Surge Protection Relay (White Backlights)

Usage: The STVP series automatic over-voltage and under-voltage protector is suitable for three-phase AC 220V, 60Hz, rated working current 80A. Its main feature is that when the circuit has over-voltage or under-voltage, the protector can cut off the power supply instantaneously to protect the electrical equipment from being damaged.
Automatic recovery connecting: the protector can automatically turn on the power supply when the circuit voltage returns to normal.
Protective Value is Settable: Overvoltage value, undervoltage value, and fault recovery delay time are adjustable.
Low Consumption LCD display: This protector can display A B C actual measured phase-to-neutral voltage, a good helper for voltage monitoring relay.
Working Voltage: 3 Phase 4 Wires, 110V/220VAC, 80A (Resistive Load)
