Description
Brand: Walfront
Characteristics:
- ✅【GOOD FUNCTION】: When the line experiences an overvoltage, undervoltage, or overcurrent condition, this product can immediately cut off the power supply to protect electrical devices from damage. When the line voltage returns to normal, the protector can automatically restart the power supply.
- ✅ 【WORKING METHODS】: This protector integrates overvoltage protection, undervoltage protection, overcurrent protection, three-phase current (voltage) unbalance protection, phase sequence protection (phase displacement protection) and phase interruption protection in one
- ✅【STABLE PERFORMANCE】: The adjustable voltage protection offers complete functions, stable performance and easy operation
- ✅【RELIABLE】: The product has the function of error query, voltmeter and ammeter as well as the function of restoring the factory settings
- ✅【FUNCTION】: The STVP series automatic reset overvoltage and undervoltage multi-function protector is a monitoring and auxiliary protection device suitable for a three-phase four-wire power supply system or electrical equipment
