Product Description

Voltage Monitoring Relay 

Protection of 3 Phase devices against Over voltage, Under voltage, Single Phasing, Reverse Phasing & Unbalance Supply are one of the major issues in electrical systems. For safe running of 3-phase devices, special protections that keep a continuous watch on supply conditions are very essential. The major cause of maximum load burn-out is overloading which occurs due to Unbalance Supply, Single Phasing & Reverse Phasing conditions. VMR-3P detects such Conditions & protect the load from burn out.

VMR-3P offer above protections along with 3 digit display showing. R-Y, Y-B, B-R voltages in scanning mode with precise accuracy. low/high voltage tripping to ensure trouble free running of 3-phase Loads.

Features :

  • Voltage protection along with digital voltage readout
  • Wide range of supply variation
  • Unit will also work if any one phase is present
  • Protection against Under voltage
  • Indications for Low voltage, High Voltage, SPP & Relay ON
  • Message Display for SPP, Reverse Phasing
  • Protection against Over voltage
  • Phase unbalance protection
  • Reverse Phasing Protection can be able to bypass through settings
  • Single Phasing & Reverse Phasing protection
  • No separate auxiliary supply required
  • All the set points settable by keys
