Product Overview
GE Multilin SR469-P5-H-A20-T belongs to the well-known 469 motor management relay family, designed for comprehensive protection, monitoring and control of large three-phase induction motors in power, water, petrochemical and heavy industrial sites. This model suffix breakdown:
- P5: 5 Amp phase CT secondary input
- H (HI): High wide-range control power supply
- A20: Four configurable 4–20 mA analog outputs
- T: 10BaseT Ethernet communication port (RJ45) + enhanced front panel
The SR469-P5-H-A20-T integrates thermal motor modeling, multi-element fault protection, real-time electrical metering, RTD temperature monitoring, fault waveform capture and Ethernet communication for SCADA/DCS connection. GE has discontinued the SR469 series. We supply fully tested surplus and refurbished SR469-P5-H-A20-T spare parts for legacy motor protection cabinet retrofit and replacement, avoiding costly full system upgrade.

FAQ
Q1: What does SR469-P5-H-A20-T suffix mean?
A: P5=5A CT secondary; H=high wide-range control power; A20=four 4-20mA analog outputs; T=10BaseT Ethernet port with enhanced display.
Q2: Is discontinued?
A: Yes, GE Multilin has phased out the entire 469 relay series. We supply surplus and fully tested replacement units for legacy motor protection systems maintenance.
Q3: What communication protocols does SR469-P5-H-A20-T support?
A: 10BaseT Ethernet Modbus TCP, plus RS485 Modbus RTU, dual communication options for plant SCADA integration.
Q4: Can SR469-P5-H-A20-T monitor motor winding temperature?
A: Yes, it supports up to 12 RTD inputs to monitor stator and bearing temperature for thermal protection.
Q5: What is the difference between SR465 and SR469 relay?
A: SR465 is basic motor management relay; SR469 is higher-end model with richer protection logic, RTD inputs and Ethernet option for larger critical motors.
