GE 469-P5-HI-A20 Motor Management Relay – Multilin 469 Series
When a critical motor fails unexpectedly on the plant floor — whether driving a compressor, pump, or conveyor — the consequences cascade instantly: unplanned downtime, production losses, and potential equipment damage that can cost tens of thousands of dollars per hour. Without intelligent motor protection, operators are left reacting to failures rather than preventing them. The GE Multilin 469-P5-HI-A20 Motor Management Relay eliminates this vulnerability by delivering comprehensive, real-time protection and monitoring that keeps your motors running safely and reliably.
The GE Multilin 469 series is one of the most trusted motor management platforms in global industrial automation. The 469-P5-HI-A20 variant occupies a premium position within this series, featuring high-interrupting (HI) current inputs and an analog output (A20) configuration that makes it ideal for demanding, high-power motor applications. Deployed across oil & gas, mining, water treatment, and heavy manufacturing facilities worldwide, the 469 series has established itself as the benchmark for comprehensive motor protection relay technology.

Frequently Asked Questions
- Q: What does the “HI” designation mean in 469-P5-HI-A20?
- A: “HI” stands for High-Interrupting current input range. This configuration is designed for motors where fault currents can be very high, ensuring the relay measures accurately without CT saturation issues.
- Q: What is the “A20” suffix in the model number?
- A: “A20” indicates the relay includes an analog output module, allowing it to transmit real-time metering data (such as current or thermal capacity) as a 4–20 mA or 0–20 mA signal to external SCADA or DCS systems.
- Q: Is the GE 469-P5-HI-A20 compatible with Modbus RTU?
- A: Yes. The 469 series supports RS-485 Modbus RTU communication, making it compatible with most modern PLC and DCS platforms. DNP3.0 is also supported.
- Q: Can this relay protect both induction and synchronous motors?
- A: The GE Multilin 469 is primarily designed for induction motor protection. For synchronous motor applications, please consult our technical team for the appropriate relay selection.
