3-Phase Voltage Monitoring Relay Phase Sequence Protector DIN Rail Mount Undervoltage Phase Failure Relay GRV8-04 M265

Adjustable and high precision: with 8 types of adjustable rated voltages and a voltage measurement accuracy of less than 1%. LED indicators: the LED indicator shows the operating status of the relay by LED indicators Top hat rail mounted: With very small volume, this relay can be mounted on a 35 mm DIN rail Voltage measurement: this relay can monitor your own working voltage (True RMS measurement) Application: the relay is often used to protect and control devices (tower lathe cranes, elevators, agricultural equipment, refrigerated vehicles) and to protect reverse rotation
