Description
Product Overview
The GE 469-P1-HI-A20-E-H is a high-performance Motor Management Relay engineered by GE Multilin to deliver advanced protection, monitoring, and control for medium to large industrial motors. As a cornerstone of the 469 series, this relay combines precision diagnostics, rugged durability, and flexible communication capabilities to ensure optimal motor performance in demanding environments. The GE 469-P1-HI-A20-E-H is specifically designed for high-voltage control power applications (90–300 VDC/70–265 VAC) and features a 1 A phase CT secondary input (denoted by “P1”), making it ideal for industries where accurate current measurement and motor health assessment are critical. Its enhanced LED display, conformal coating for harsh environments, and modular draw-out design position it as a reliable solution for sectors such as oil & gas, power generation, and manufacturing.
The relay’s advanced thermal model integrates RTD biasing and negative sequence current feedback to prevent overheating and predict stator winding faults. With 9 optically isolated digital inputs and 4 analog outputs (0–1 mA), it enables seamless integration with SCADA systems and PLCs, while Modbus RTU communication ensures real-time data exchange. The GE 469-P1-HI-A20-E-H also supports broken rotor bar detection through motor current signature analysis (MCSA), reducing downtime by identifying mechanical issues before they escalate. By combining comprehensive protection, intuitive diagnostics, and user-friendly configuration, this relay empowers industries to enhance motor reliability and operational efficiency.

Main Features and Advantages
Precision Motor Protection
The GE 469-P1-HI-A20-E-H offers voltage-dependent overload curves that adjust dynamically based on motor acceleration and system voltage, critical for high-inertia applications. Its dual overload curves support two-speed motors, while stator differential protection and underfrequency monitoring guard against abnormal operating conditions. The relay’s thermal memory retains real-time thermal capacity data, ensuring accurate protection even after power interruptions.
Advanced Diagnostics
Equipped with motor current signature analysis (MCSA), the relay detects early signs of broken rotor bars or bearing degradation, enabling predictive maintenance. The oscillography feature records up to 128 cycles of waveform data during faults, simplifying root-cause analysis. With 12 RTD inputs (optional), it monitors stator temperature directly, enhancing thermal protection accuracy.
Rugged Design
The conformal coating safeguards internal components from dust, moisture, and chemical corrosion, making it suitable for hazardous environments. The draw-out case design allows quick module replacement without rewiring, minimizing downtime. The relay’s -40°C to +60°C operating range ensures reliable performance in extreme temperatures.
Seamless Integration
Featuring Modbus RTU and optional Ethernet/DeviceNet connectivity, the GE 469-P1-HI-A20-E-H integrates effortlessly with existing automation systems. The Enervista™ software provides remote configuration, data logging, and waveform analysis, streamlining commissioning and ongoing management.
Application Areas
Industrial Machinery
The GE 469-P1-HI-A20-E-H excels in protecting motors for pumps, compressors, and conveyors in manufacturing plants. Its start supervision function ensures safe motor acceleration, while mechanical jam detection prevents damage from blocked equipment.
Power Generation
In power plants, this relay monitors turbine-driven pumps and fans, providing voltage-compensated acceleration to maintain stable operations. Its undervoltage protection prevents motor damage during grid fluctuations.
