  • 【High Accuracy】: The voltage relay has 8 adjustable rated voltages, and the voltage measurement accuracy is less than 1%.
  • 【Rated Voltage】: Rated Voltage up to 552AC Voltage measurement accuracy<1%.
  • 【3-Phase Design】: This Current Monitoring Relay is designed with 3-Phase Monitoring Relay to provide a correct phase sequence, without neutral, phase Loss and Incorrect phase sequence, so it can detect when all phases are present and have the correct sequence
  • 【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.
