Description
GE Multilin 760-P1-G1-S1-LO-A20-R-E Product Description
Product Overview
GE Multilin 760-P1-G1-S1-LO-A20-R-E is a 760 Series Feeder Management Relay designed for protection, control, monitoring, metering, and automation of medium- and low-voltage electrical distribution feeders. It is part of the GE Multilin 750/760 Feeder Management Relay family. The exact configuration combines 1 A phase-current inputs, 1 A zero-sequence current inputs, 1 A sensitive-ground input, low-voltage control power, eight 4–20 mA analog outputs, red breaker-status indication, and the enhanced-display version.
The “-E” suffix identifies the enhanced version of the relay. Compared with the base 760-P1-G1-S1-LO-A20-R, the enhanced configuration provides an enhanced display and associated functionality; comparable GE Multilin listings describe the enhanced version with Ethernet connectivity.

Main Features and Advantages
Comprehensive Feeder Protection
The 760-P1-G1-S1-LO-A20-R-E provides protection and management functions for electrical distribution feeders. It can monitor feeder current and detect abnormal operating conditions, supporting protection against overcurrent and ground-fault conditions.
1 A CT Input Configuration
This specific order code is configured for 1 A current-transformer inputs, including phase and zero-sequence/sensitive-ground measurement. Correct CT secondary rating is essential when replacing the relay; a 5 A version of the 760 series should not be treated as a direct substitute.
760-P1-G1-S1-LO-A20-R
Eight 4–20 mA Analog Outputs
The A20 option provides eight 4–20 mA analog outputs, allowing measured electrical quantities or calculated values to be transmitted to a PLC, DCS, SCADA system, recorder, or other plant instrumentation.
Enhanced Display
The R-E configuration incorporates the enhanced-display option, providing a more capable local operator interface for viewing measured values, alarms, status information and relay settings. The related 760 configuration documentation identifies the enhanced display with Ethernet on comparable order codes.
Communication and Data Recording
The relay supports Modbus RTU and DNP 3.0 communication, while the enhanced configuration can provide Ethernet connectivity. Event recording and waveform capture functions provide useful information for fault investigation and preventive maintenance.
Drawout Construction
The 760 relay is designed as a drawout unit, allowing the relay electronics to be removed from its case for maintenance or replacement. The case itself is normally a separate component, which is important when sourcing replacement equipment.
Application Fields
Electrical Distribution Feeders
The primary application of 760-P1-G1-S1-LO-A20-R-E is protection and management of distribution feeders. It can monitor current, detect faults, provide breaker-related status, and communicate operational information to a supervisory system.
Industrial Power Systems
The relay is suitable for industrial plants with internal medium-/low-voltage distribution networks. Typical applications include feeders supplying motors, transformers, process equipment and auxiliary loads.
Power Generation
In generating plants, the relay can provide feeder protection for auxiliary distribution systems and plant electrical networks, helping isolate faults while maintaining availability of unaffected equipment.
Oil & Gas and Petrochemical
Refineries, petrochemical plants and oil-and-gas facilities require dependable protection of electrical distribution systems. The 760 can provide feeder monitoring, protection and SCADA communication in these environments.
Water and Infrastructure
Water-treatment plants, pumping stations and other infrastructure facilities can use feeder management relays to protect electrical distribution equipment and provide electrical measurements to centralized control systems.
Industrial Retrofit
The exact 760-P1-G1-S1-LO-A20-R-E configuration is particularly valuable for maintaining existing GE Multilin 760 installations. Matching the entire order code is important because the 760 family includes numerous variants with different CT inputs, power supplies, analog outputs and display/communication options.
