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

KWD 12
– 1 +

Special Features

  • High Accuracy: The voltage relay has 8 adjustable rated voltages, and the voltage measurement accuracy is less than 1%.
  • 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.
  • LED Indicator: The working status of the voltage control relay is indicated by the LED indicator.
  • Convenient Monitoring: The voltage relay can monitor its own operating voltage (true rms measurement).
  • Small Size and Easy to Install: The voltage protection relay is ultra-small and can be mounted on a 35mm DIN rail.
