WESTINGHOUSE PVR-1C 3 PHASE MONITOR (Part Number 9083A88G03) 480V INPUT

Description:

The Westinghouse PVR-1C (Part Number 9083A88G03) is a three-phase voltage monitoring relay designed to protect motors, pumps, compressors, and other three-phase equipment from damaging power conditions. Operating from a 480 VAC three-phase input, the relay continuously monitors phase loss, phase reversal, phase imbalance, and undervoltage conditions. When an abnormal condition is detected, the relay activates its output contacts to shut down or alarm connected equipment, helping prevent motor damage and unplanned downtime.

Applications:

The Westinghouse PVR-1C phase monitor is commonly used in motor control centers, HVAC systems, pumping stations, compressors, conveyors, manufacturing equipment, water treatment facilities, and industrial process systems. It provides phase monitoring protection for three-phase motors and electrical equipment operating on 480V power systems.
