GE Multilin 760-P5-G5-S5-HI-A20-R-E Product Description
Product Overview
GE Multilin 760-P5-G5-S5-HI-A20-R-E is a 760 Series Feeder Management Relay designed for protection, control, metering, monitoring, event recording, and automation of electrical distribution feeders. It is the enhanced-display configuration of the GE Multilin 760 feeder relay, with 5 A phase-current, 5 A zero-sequence, and 5 A sensitive-ground inputs, high-range auxiliary power, eight 4–20 mA analog outputs, and a red breaker-closed indicator.
GE’s own 750/760 documentation defines the order-code structure and specifically identifies the combination 760-P5-G5-S5-HI-A20-R-E as the enhanced 760 Feeder Management Relay.

The P5, G5, and S5 codes respectively identify 5 A phase-current, 5 A zero-sequence, and 5 A sensitive-ground inputs. HI specifies the high-range control supply, while A20 specifies eight 4–20 mA analog outputs and R specifies the red breaker-closed LED.
Main Features and Advantages
Comprehensive Feeder Protection
The 760-P5-G5-S5-HI-A20-R-E provides a comprehensive digital protection platform for electrical feeders. The 760 family integrates protection, metering, monitoring, control and recording functions into a single relay, reducing the need for multiple dedicated monitoring devices.
5 A CT Configuration
This particular model is configured for 5 A secondary current transformers on phase, zero-sequence and sensitive-ground inputs. This is a critical procurement parameter because the 760 family also contains 1 A variants.

High-Voltage Auxiliary Supply
The HI option accepts a wide auxiliary-power range of 88–300 VDC or 70–265 VAC at 48–62 Hz, making the relay suitable for common high-voltage station/control-power systems.
Eight 4–20 mA Outputs
The A20 option provides eight 4–20 mA analog outputs. These outputs can be used to transmit measured or calculated electrical parameters to a PLC, DCS, SCADA system, recorder, or other plant instrumentation.
Enhanced Operator Display
The E configuration provides the enhanced display with a larger LCD, improving local access to relay measurements, status information, alarms and settings. GE’s documentation explicitly distinguishes the enhanced display from the basic display configuration.
Event and Waveform Recording
The relay can capture event information and waveform data, providing valuable records for fault analysis, commissioning, troubleshooting and preventive maintenance. The 760 platform supports waveform recording at 16 samples per cycle according to the available instruction manual.
Autoreclose Function
The 760 is the feeder-management version incorporating automatic reclosing, making it suitable for distribution feeders where temporary faults may be cleared and service restored automatically after the protection sequence. GE documentation identifies the 760 as the relay variant with autoreclose.
Application Fields
Electrical Distribution Feeders
The primary application is medium- and low-voltage feeder protection and management. The relay continuously monitors feeder currents and can initiate protection and control actions when abnormal electrical conditions occur.
Power Generation Plants
The relay can protect plant auxiliary feeders, generator auxiliaries and distribution circuits in power-generation facilities. Its metering and recording capabilities also provide useful information for plant electrical maintenance.
Oil & Gas and Petrochemical
In refineries and petrochemical plants, the 760 can protect feeders supplying pumps, compressors, motors, transformers and process equipment. Its communication and analog-output capabilities allow electrical information to be incorporated into plant supervisory systems.
Mining and Metals
Mining, steel and other heavy industries often use high-power distribution networks with numerous feeders. The 5 A CT configuration and broad control-power range make this model suitable for compatible industrial switchgear applications.
Water and Infrastructure
Water-treatment plants, pumping stations and other infrastructure facilities can use the relay for feeder protection, breaker monitoring, electrical measurement and remote supervisory integration.
Utility Substations
The 760 platform is applicable to distribution-substation feeder protection where automatic reclosing, fault recording and remote monitoring are required.
