EKR8-7 3-Phase Voltage Monitoring Relay Phase Sequence Phase Failure Protection

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.

Product Profile

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.

1. Convenient Monitoring: The voltage relay can monitor its own operating voltage (true rms measurement).
2. Application: Equipment protection and control (tower cranes, elevators, agricultural equipment, refrigerated trucks); prevent reverse operation of equipment; normal/emergency power switch; prevent phase failure of dynamic loads.
3. LED Indicator: The working status of the voltage control relay is indicated by the LED indicator.
4. Small Size and Easy to Install: The voltage protection relay is ultra-small and can be mounted on a 35mm DIN rail.
