LPRC/2HV RELAY

Product Description

The LPRC/2HV Relay is a high-voltage three-phase monitoring relay used for protecting and controlling industrial electrical systems. It is designed to monitor voltage conditions, phase sequence, phase failure, and imbalance in 3-phase supply systems and automatically disconnect the load when unsafe conditions occur.

It belongs to the LPRC series of industrial protection relays, commonly used in motors, pumps, compressors, generators, and control panels to prevent equipment damage due to abnormal voltage conditions.

Key Features

• Three-phase voltage monitoring relay for industrial protection
• Detects overvoltage and undervoltage conditions (window monitoring)
• Phase failure and phase sequence protection
• Phase imbalance/asymmetry detection (model dependent)
• High-voltage compatible variant (HV series) for industrial supply systems
• Dual relay outputs for independent control functions
• Adjustable trip levels and time delay settings
• LED indicators for power, fault, and relay status
• DIN rail mounting for easy panel installation
• Designed for continuous industrial operation and system safety
