YWBL-WH GRV8-04 M460 Voltage Relay,3-Phase Voltage Monitoring Relay Phase Sequence Phase Failure

YWBL-WH GRV8-04 M460 Voltage Relay,3-Phase Voltage Monitoring Relay Phase Sequence Phase Failure

Application: Equipment and control (tower cranes, elevators, agricultural equipment, refrigerated trucks); prevent reverse of equipment; normal/emergency power switch; prevent phase failure of dynamic loads. LED Indicator: The working status of the voltage control relay is indicated by the LED indicator. High Accuracy: The voltage relay has 8 adjustable rated voltages, and the voltage measurement accuracy is less than 1%. Convenient Monitoring: The voltage relay can monitor its own operating voltage (true rms measurement). Small Size and Easy to Install: The voltage relay is ultra-small and can be mounted on a 35mm DIN rail. Specification:
