Functional Role & Application Analysis
The GE SR469-P5-HI-A20-E serves as a comprehensive motor management relay within the Multilin 469 family. It solves the critical need for protecting and controlling medium-voltage electric motors by providing integrated thermal modeling, precise fault isolation, and real-time diagnostic monitoring. This module acts as the primary safeguard, ensuring that industrial motors are shielded from destructive conditions like overload, stall, and ground faults while maintaining continuous operational visibility.
Typical use cases include:
- Comprehensive protection for large industrial motors in petrochemical plants and water treatment facilities.
- Real-time thermal capacity monitoring and predictive maintenance for critical pumping and compressor stations.
- Critical maintenance and direct replacement in legacy Multilin 469 installations to prevent unplanned motor failures and production downtime.
Our Quality Standard & Testing Process
We understand that the cost of an unreliable part is far greater than its purchase price. We have established a rigorous, multi-stage testing process to ensure every product we ship is 100% functional and ready for immediate deployment.
- Visual & Component Inspection: All parts undergo professional cleaning and visual inspection to ensure no physical damage, corrosion, or compromised components.
- Live System Test: The module is installed in a live GE Multilin test rack and run for 24 hours to verify continuous operation and power stability.
- Full-Function Diagnostics: We simulate 5A CT inputs and trigger all protection logic to test the full range, relay contact actuation, and analog output accuracy.
- Warranty Backing: Only parts that pass all diagnostic tests are approved for shipment and backed by our full 12-month warranty.

Compatibility & Migration Paths
To ensure this SR469-P5-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.
- Firmware/Hardware Revisions: You must confirm your existing motor control architecture supports this specific relay hardware revision. Earlier software configurations may require parameter adjustments.
- Required Components: This module is designed to work with specific 5A phase CTs. Verify your existing current transformers match the 5A secondary rating to ensure accurate protection tripping.
- Replacement & Alternatives: This model is a direct drop-in replacement for older 469 series relays with identical P5-HI-A20-E suffixes. If your application requires lower voltage control power, you may also consider the SR469-P1-HI-A20-E.
