Product Overview

The 750-P5-G5-S5-HI-A1-R-E-H is a GE Multilin SR750 feeder management relay used for protection, control, and monitoring of electrical distribution feeders. It is commonly applied in switchgear and substation-style panels where a single device is required to combine protective elements, metering, event reporting, and operator interface functions.

This relay supports feeder supervision with configurable protection logic and communications for integration into plant control or SCADA environments. The model code identifies the installed hardware options such as current input ratings, supply range, and communications/interface features.
