Voltage Monitoring Relay single Phase MODEL: VMR 1P

Protection of electrical devices against Over voltage, Under voltage in the supply is one of the major issue in electrical systems. For safe running of electrical devices, special protections that keep a continuous watch on supply conditions are very essentials. 'PROTONs VMR 1P' offer following protections along with 3 digit display showing R-N(L-N) voltage in scanning mode with precise accuracy. LOW/HIGH voltage(settable) tripping to ensure trouble free running of Loads.
