EKR8-7 Single Phase Voltage Monitoring Protection Relay Adjustable Over or Under Voltage

Voltage protection relay uses a high-speed and low power processor as its core. When the power supply line has over-voltage, under-voltage, or phase failure, phase reverse, the relay will cut off the circuit quickly and safely to avoid accidents caused by abnormal voltage being sent to the terminal appliance.

Porduct Overview

Single Phase Voltage Monitoring Relays are designed for protection of single-phase load against un-allowable voltage variations in the mains. They have a wide range of adjustments, including power on time delay for protection of refrigerating, compressor and air-conditioning equipment.
 

1. Cut off the line when Over & Under Voltage occurs, and automatically reset and connect the line after 

returning to normal without manual operation.

2. When the line appears transient or transient Over& Under Voltage, the protector does not malfunction.
