Product Overview

The 745-W3-P511-G51-HI-R-E is a GE Multilin SR745 feeder management relay used in distribution protection and control panels. It is designed to combine protection, metering, monitoring, and local operator interface functions in a single relay platform for power feeders and associated equipment. In typical installations, the relay supports continuous supervision of electrical conditions and provides event-driven alarming to assist with operational reliability and maintenance response.

This model is commonly deployed in switchgear lineups and substation-style panels where rugged front-panel interaction, configurable settings, and integration with plant monitoring systems are required.
