GE 760-P5-G5-S5-HI-A20-R-E

Product Introduction

The GE 760-P1-G1-S1-LO-A20-R is a compact, cost-effective motor and feeder management relay designed for low-power industrial applications. As a member of GE’s 760 series, it shares the core philosophy of reliable protection and monitoring with the 760-P5-G5-S5-HI-A20-R-E but is optimized for smaller-scale electrical systems where lower current ratings and reduced power consumption are priorities.

This relay handles 1A current inputs—ideal for applications with smaller motors and feeders—and operates on a low control power range (24 – 60 VAC/DC), making it suitable for decentralized systems or installations with limited power resources. Its streamlined feature set includes essential protective functions and basic monitoring capabilities, ensuring robust performance without unnecessary complexity.

The 760-P1-G1-S1-LO-A20-R retains the 760 series’ user-friendly design, with an LCD display for at-a-glance status updates and flexible communication options for integration into existing control networks. It strikes a balance between functionality and affordability, making it a practical choice for light industrial and commercial electrical systems.

Core Advantages and Technical Highlights

Optimized for low-power systems: The 760-P1-G1-S1-LO-A20-R is purpose-built for 1A current inputs and low control power, reducing energy consumption in applications like small motor control panels or distributed lighting systems. Unlike the higher-power 760-P5-G5-S5-HI-A20-R-E, it eliminates the need for step-down transformers in low-current circuits, simplifying installation and lowering costs.

Essential protection in a compact form: While offering fewer advanced features than its HI counterpart, this relay delivers critical protection functions: phase overcurrent detection, ground fault monitoring, and under/overvoltage protection. Its basic reclosure function handles temporary faults in distribution lines, automatically restoring power after verifying fault clearance—critical for maintaining uptime in retail or commercial buildings.

Simplified integration: With a focus on ease of use, the 760-P1-G1-S1-LO-A20-R features plug-and-play compatibility with standard Modbus RTU networks. Its RS485 interface allows seamless communication with SCADA systems or HMIs, while the optional Ethernet module extends connectivity for remote monitoring. This makes it ideal for retrofitting older systems where minimal wiring modification is desired.

Cost-effective scalability: For facilities with mixed power requirements, the 760-P1-G1-S1-LO-A20-R complements the 760-P5-G5-S5-HI-A20-R-E perfectly. It can protect auxiliary systems (e.g., small pumps, fans) alongside its higher-powered sibling, creating a unified protection ecosystem with consistent programming and monitoring via GE’s Enervista software.

Typical Application Scenarios

Commercial and retail facilities: In shopping malls or office complexes, the 760-P1-G1-S1-LO-A20-R protects HVAC motors, elevator sub-systems, and lighting panels. Its low-power design integrates seamlessly with building management systems, monitoring current draw in real time to prevent overloads in lighting circuits or small air-handling units. The relay’s compact size fits easily into tight electrical enclosures, a common constraint in retrofitted commercial spaces.

Light industrial operations: Small manufacturing workshops or food processing plants use this relay to safeguard conveyors, mixers, and packaging machinery. For example, in a bakery, it can detect phase imbalances in dough mixer motors, shutting down the equipment before damage occurs. Its basic reclosure function minimizes downtime from temporary faults, such as momentary overloads during peak production.

Renewable energy microgrids: In solar or wind microgrids, the 760-P1-G1-S1-LO-A20-R manages feeder lines connecting distributed energy resources (DERs) to the main grid. It monitors power flow from small-scale inverters, detects reverse power conditions, and isolates faulty sections to protect sensitive DER equipment—all while operating on the microgrid’s low-voltage power supply.

Related Model Recommendations

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing the 760-P1-G1-S1-LO-A20-R, confirm the control power supply matches the 24 – 60 VAC/DC range using a multimeter. Ensure the 19-inch panel or DIN rail has adequate ventilation, as specified in the GE installation guide. Use anti-static tools when handling the relay to prevent ESD damage. For retrofits, verify that current transformers (CTs) are rated for 1A secondary output to match the relay’s input requirements.

Commissioning: Power up the system and use the LCD menu or Enervista software to configure current thresholds, trip delays, and communication settings. Calibrate analog outputs using a precision multimeter, ensuring 4mA corresponds to 0% and 20mA to 100% of the measured parameter. Test protective functions by simulating a ground fault or overcurrent—confirm the relay trips within the set time and logs the event. Verify Modbus communication with the master controller to ensure remote monitoring works correctly.

Maintenance suggestions: Conduct quarterly visual inspections of the 760-P1-G1-S1-LO-A20-R for loose terminals or dust buildup; clean vents with compressed air. Review logged events monthly via Enervista to identify recurring issues (e.g., frequent overloads indicating motor degradation). Replace the relay’s backup battery every 5 years to preserve configuration data during power outages. For fault troubleshooting, use the LCD’s error codes or waveform capture (if enabled) to isolate issues—refer to GE’s troubleshooting guide for common scenarios.
