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 LVM 3P' offer above protections along with 3 digit display showing R-Y,Y-B,BR voltages in scanning mode with precise accuracy. LOW/HIGH voltage tripping to ensure trouble free running of 3-phase Loads. 
Additional auxiliary supply not required.

• Latest micro controller based technology.
• Wide range of supply variation.
• Unit also works with one phase is present.
• Additional auxiliary supply not required.
• Protection against Under voltage.
• Protection against Over voltage.
• Single Phasing & Reverse Phasing protection.
• Reverse Phasing Protection can be bypased through settings.
• Trip delays for all protections.
• Set Parameters are easy to handle with simple trimpot.

• LED indication for status of relay & Power.
