Voltage Monitoring Relay Three Phase MODEL: VMR-3P
Protection of 3 Phase devices against Over voltage, Under voltage,Single Phasing, Reverse Phasing & unbalance supply are one of the major issue 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.
VMR3P detects such Conditions & protect the load from burn out. 'PROTON's 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.
