Description
Product Overview
The GE 469-P5-HI-A20-E is an advanced motor management relay designed by GE Multilin, belonging to the SR 469 series platform. Engineered for medium to large AC motors in industrial applications, this relay delivers comprehensive protection, control, and monitoring with adaptive features to optimize motor performance and reduce downtime. Its modular design supports drawout or fixed mounting, making it suitable for both new installations and retrofitting existing motor control centers.
Key functions include thermal overload protection with voltage-dependent curves, stator differential protection, and broken rotor bar detection through advanced motor current signature analysis (MCSA)216. The relay features 12 RTD inputs for real-time temperature monitoring of motor windings and bearings, ensuring precise thermal modeling and early fault detection. With support for Modbus RTU, DeviceNet, and IEC 61850 communication protocols19, it enables seamless integration into smart grid systems for remote diagnostics and SCADA integration. The enhanced front-panel LCD display (40-character) and Enervista software provide intuitive configuration and real-time metering of voltage, current, torque, and power quality parameters.
