Product Introduction
The GE 469-P5-HI-A20-E is a Multilin SR469-series motor management relay designed for medium-voltage and critical low-voltage motors. It provides thermal overload protection, ground-fault protection, phase loss/unbalance, jam/stall detection, start supervision, and RTD-based temperature monitoring.
The “P5” option means the relay is configured for 5 A phase CT secondaries. The “HI” control power typically accepts 70–265 VAC and 90–300 VDC, 48–62 Hz. The “A20” option adds four isolated 4–20 mA analog outputs for retransmitting motor current, thermal capacity, power, or temperature to a DCS/PLC. The “E” suffix indicates the enhanced faceplate with a 40-character alphanumeric LCD, RS-232 service port, and local programming keys.
The SR469 platform has been discontinued; GE’s successor platforms include the Multilin 859/869 series.

Quality Control Process (DYNAMIC GENERATION)
- Ordering code verification: Confirm 469-P5-HI-A20-E matches P5, HI, A20, and E options; check for optional conformal coating if required.
- Control power test: Apply 70–265 VAC or 90–300 VDC and verify stable boot, display, and LED indication.
- CT and ground-fault check: Inject 5 A phase current and ground CT current; verify overload, unbalance, stall, and ground-fault responses.
- Analog output calibration: Verify all four 4–20 mA outputs against a precision meter and confirm scaling for current, thermal capacity, or temperature.
- Communication and RTD validation: Test RS232/RS485 connectivity via EnerVista 469, verify RTD readings, then pack in anti-static protective packaging.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Do not mix P5 and P1. P5 is for 5 A CT secondaries; replacing it with a P1/1 A unit on 5 A CTs will cause incorrect current measurement and protection errors.
❗ Confirm analog output scaling. The A20 option provides 4–20 mA outputs; substituting an A1/0–1 mA version will break DCS/PLC integration.
❗ Verify RTD and communication options. The base code 469-P5-HI-A20-E does not fully define RTD count, Ethernet, or conformal coating; check the full nameplate or order suffix.
❗ Plan for 469 discontinuation. The 469 series is no longer manufactured; long-term replacements should evaluate migration to the GE Multilin 859 or 869.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
