Voltage Protection Relay

Omicron - VR monitors AC voltage of a system/equipment and protects it from overvoltage, undervoltage and phase failure issues. As well as it indicates the occurrence of faults with help of LED indications.








  • Protection feature: Under voltage, Over voltage protection as well as protection against Phase unbalance, Phase failure, Incorrect phase sequence & Neutral failure
  • Compact size : Width of 17.5 mm
  • True RMS measurement
  • LED indication for faults
  • Disabling of Over & Under Voltage fault on site is possible
  • Onsite selection of VLL / VLN value based tripping
  • Self powered
  • Adjustable Nominal voltage, Trip point, Trip time delay
  • Compliance to International Safety standard IEC 61010-1-2010
