Product Introduction
GE 469-P1-HI-A20-E is a Multilin SR469 motor management relay for medium to large motors. It handles protection, monitoring, and control in industrial motor circuits, with local indication on an enhanced LCD.
This model is often used in retrofit and maintenance work where the existing relay footprint and wiring must stay unchanged. Verify the supply range, current transformer ratios, and exact suffix before ordering.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Relay is dead, no display | No control power, blown fuse, or internal failure | ✅ High | Measure supply voltage at the relay terminals and check the fuse | Verify power first before replacing the relay |
| Motor trips on overload too early | Wrong motor settings, CT mismatch, or thermal model error | ✅ High | Compare nameplate FLA, CT ratio, and overload settings | Re-enter settings before calling the relay bad |
| Communication does not respond | Wrong baud rate, wiring error, or bad address | ✅ High | Check Modbus wiring, node address, and serial settings | Verify communications setup first |
| False ground fault trip | CT wiring issue, external fault, or configuration error | ✅ High | Inspect CT polarity and review the event log | Confirm wiring and settings before replacement |
| Display works but outputs do not operate | Output relay failure or logic issue | ✅ High | Test output contacts and review logic functions | If contacts fail under test, replace the unit |
| Values look wrong but relay is healthy | Instrument transformer or configuration problem | ⚠️ Medium | Compare measured currents and voltages with a clamp meter | Check field instrumentation before swapping hardware |
If you are stuck, send photos of the relay, wiring terminals, and trip logs to technical support.
Frequently Asked Questions
Q: What is the 469-P1-HI-A20-E used for?
A: It is a GE Multilin SR469 motor management relay used to protect and monitor medium to large motors.
Q: Is this part obsolete?
A: Yes, it is a legacy product, so most available stock is surplus, refurbished, or recovered inventory.
Q: Can I drop in a newer relay instead?
A: Sometimes, but not without checking panel size, wiring, CT/PT ratios, control supply, and logic requirements. A newer relay often needs rework.
Q: Is it hot-swappable?
A: No. Power down the circuit before removal. Pulling it live can damage the relay or the control wiring.
Q: Why is surplus cheaper than factory new?
A: Because it usually comes from excess inventory, project closeouts, or removed equipment. The lower price is fine if the condition and test status are clearly stated.
Q: What should I verify before ordering?
A: Confirm the exact part number, supply range, CT/PT settings, firmware, and panel compatibility. That prevents the usual mistake of buying the right family but the wrong configuration.
