GE Multilin 750-P5-G5-S5-LO-A20-R-E Feeder Management Relay

Product Description

The GE Multilin 750-P5-G5-S5-LO-A20-R-E is a microprocessor-based feeder management relay designed to provide electrical feeder protection, measurement, and monitoring. This configuration specifies 5 A phase current inputs, 5 A ground current inputs, 5 A sensitive ground current inputs, and a low-range control power supply. It also includes eight 4-20 mA analog outputs, a red breaker-closed LED indicator, and an enhanced display.

Hardware Specifications

Protection and Monitoring Functions

The 750 relay monitors feeder electrical quantities through its phase-current, zero-sequence ground-current, and sensitive ground-current inputs. These inputs support protection functions selected and configured through the relay settings. The actual pickup levels, operating delays, and enabled protection elements depend on the application settings.

The supplied configuration includes eight 4-20 mA analog outputs for transmitting assigned measurement or monitoring values to external equipment. The red breaker-closed LED provides a local status indication, while the enhanced LCD supports front-panel access to relay information and settings.

Configuration Identification

Frequently Asked Questions

Q: What should be checked when replacing a 750-P5-G5-S5-LO-A20-R-E?

A: Verify the complete order code, current-transformer secondary ratings, control supply, analog output requirements, display version, and existing protection settings. Confirm the replacement relay's wiring and configuration before returning the feeder to service.

Q: What control power does the LO version require?

A: The published 750/760 ordering information specifies 25-60 VDC or 20-48 VAC at 48-62 Hz for the LO version. Check the equipment nameplate and the applicable manual revision before connecting the supply.

Q: Is the GE Multilin 750 series still manufactured?

A: GE Vernova lists the 750/760 series as discontinued and identifies the 850 as an alternative product family. The 850 should not be treated as a direct drop-in replacement without checking protection functions, wiring, dimensions, communications, and configuration requirements.
