Functional Role & Application Analysis
The GE SR469-P1-HI-A20-E is a highly specialized motor management relay from the Multilin 469 series. It is primarily used to solve the critical need for comprehensive motor protection and real-time asset monitoring in heavy industrial environments. This relay provides advanced thermal modeling, continuous metering, and precise protection algorithms to prevent catastrophic motor failures and minimize unplanned downtime.
Typical use cases for this module include:
- Critical Motor Protection: Safeguarding high-voltage and medium-voltage motors in petrochemical, mining, and power generation facilities against thermal overload and mechanical faults.
- Asset Monitoring & Metering: Continuously tracking motor health parameters, including temperature (via RTDs), vibration, and power consumption, to enable predictive maintenance.
- Legacy System Maintenance: Serving as a direct replacement component in aging GE Multilin 469 installations to restore essential motor protection without requiring a full system retrofit.
Our Quality Standard & Testing Process
We understand that the cost of an unreliable part is far greater than its purchase price. A failed motor protection relay can result in the complete destruction of an expensive industrial motor. We have established a rigorous, multi-stage testing process to ensure every SR469-P1-HI-A20-E we ship is 100% functional and ready for critical duty.
- Visual & Component Inspection: All parts undergo professional cleaning and detailed visual inspection under magnification to ensure no physical damage, corrosion, or compromised solder joints exist on the board.
- Live System Test: The module is installed in a live Multilin test environment and run for a minimum of 24 hours to verify continuous operation, thermal stability, and internal logic processing.
- Full-Function Diagnostics: We simulate real-world 1A CT inputs and 4-20mA analog loads to test the full range of protection curves and metering accuracy, ensuring precise calibration.
- Warranty Backing: Only parts that pass all diagnostic tests are approved for shipment and backed by our full 12-month warranty, giving you complete confidence in your spare parts strategy.

Compatibility & Migration Paths
To ensure this SR469-P1-HI-A20-E is 100% compatible with your system, you must check these key compatibility points. Failure to verify this is a common project risk that can lead to installation failures or unprotected motors.
- CT Input Sizing: You must confirm your existing Current Transformers (CTs) are 1A secondaries. This specific model (-P1-) is strictly for 1A CTs. If your system uses 5A CTs, you require the -P5- variant.
- Control Power Voltage: Verify your control power supply is 25-60 VDC or 20-48 VAC. This model does not support high-voltage AC control power (which requires the -HI- power suffix).
- Analog Output Configuration: This model features 4-20 mA analog outputs. Ensure your downstream PLC or SCADA system is configured to receive this signal range, as opposed to 0-1 mA outputs.
