Product Overview

The GE 469-P5-AI-A1-E-H is a high-performance motor protection system from GE Multilin’s esteemed SR series, designed to provide comprehensive protection, control, and condition monitoring for medium and large three-phase induction motors . This advanced motor management relay integrates dozens of protection functions within a microprocessor-based platform, delivering real-time monitoring of motor current, voltage, and temperature to detect anomalies before they escalate into costly failures . The 469-P5-AI-A1-E-H is specifically configured with the P5 phase CT input (5A secondary), AI analog output option (4-20mA), and H high-power control supply (88-300 VDC / 70-265 VAC), making it suitable for demanding industrial applications.

As a member of the SR family, the GE 469-P5-AI-A1-E-H offers a cost-effective, industry-leading draw-out construction with automatic CT shorting upon removal, enabling field replacement without powering down the entire system . The 469-P5-AI-A1-E-H features an advanced thermal model biased by RTD and negative sequence current feedback, ensuring accurate thermal capacity calculations and reducing nuisance tripping . With up to 12 RTD inputs, 4 analog inputs, 4 analog outputs, and 6 programmable output relays, the GE 469-P5-AI-A1-E-H provides exceptional flexibility for integration into new and existing automation networks .

The E suffix indicates the inclusion of a 10Base-T Ethernet port supporting Modbus TCP/IP, complementing the standard RS232 and two RS485 serial ports for comprehensive communication capabilities . Manufacturing for the 469 series has been discontinued by GE Vernova, making the GE 469-P5-AI-A1-E-H a legacy product available primarily through authorized spare parts channels, with the 859 and 869 relays serving as the recommended alternatives .
