Selection Guide
Use the following criteria to determine whether the GE GEUR7CM or an equivalent model best fits your application:
- Step 1 – Define protection functions required: List ANSI function codes needed (e.g., 50, 51, 50N, 51N, 67)
- Step 2 – Confirm auxiliary supply voltage: Match relay aux supply to available panel supply (DC or AC)
- Step 3 – Check CT/VT ratios: Ensure relay input ratings match installed instrument transformers
- Step 4 – Evaluate communication protocol: Confirm SCADA protocol (Modbus, IEC 61850, DNP3)
- Step 5 – Assess mounting & form factor: Verify panel cutout dimensions and rack compatibility
- Step 6 – Review certifications: Confirm IEC / IEEE compliance for your regional grid code

Replacement & Compatibility FAQ
Q: Is the GE GEUR7CM still in production?
A: GE Multilin product availability changes over time. Contact us to confirm current production status and available stock.
Q: Can the ABB REF615 directly replace the GEUR7CM?
A: Functionally yes for most overcurrent/earth fault applications, but wiring, CT/VT connections, and SCADA configuration must be re-engineered. A protection engineer review is recommended.
Q: Do you supply the GE GEUR7CM with a test certificate?
A: Yes, factory test certificates and COC documents are available upon request for most units.
Q: What is the difference between GEUR7CM and GEUR7CM-A?
A: Suffix variants typically indicate firmware version, communication option, or auxiliary supply range differences. Contact us with your exact requirement for clarification.
Q: Can I use the Siemens 7SJ85 as a drop-in replacement?
A: The 7SJ85 offers equivalent protection functions but requires panel modification for mounting and wiring adaptation. Not a direct drop-in without engineering review.
