Why Engineers Specify This Model
- Unified Platform Architecture – The UR series allows engineers to standardize on a single hardware platform across multiple protection functions, reducing spare-parts inventory and training overhead.
- IEC 61850 Native Support – GOOSE messaging enables peer-to-peer relay communication without hardwired I/O, simplifying substation wiring and enabling faster fault clearance.
- Flexible Configuration via EnerVista Software – GE’s EnerVista UR Setup tool provides intuitive logic programming, settings management, and real-time monitoring without proprietary hardware.
- High Reliability & Proven Field Record – Thousands of UR-series relays are installed globally in utility and industrial environments, with a documented MTBF exceeding 100,000 hours.
- Cybersecurity Compliance – Supports NERC CIP-compliant access control and role-based authentication for critical infrastructure deployments.

Application-Specific FAQ
Q: Is the GE UR8FH compatible with the older UR-series chassis?
A: The UR8FH is designed for the 8-slot UR chassis. Compatibility with older chassis generations depends on firmware and hardware revision — contact us with your chassis model for confirmation.
Q: Can the UR8FH be configured for both overcurrent and differential protection simultaneously?
A: Yes. The UR platform supports multi-function protection logic. The specific functions available depend on the ordered feature set (order code suffix). The UR8FH typically supports a broad protection function library configurable via EnerVista software.
Q: Do you provide the EnerVista configuration software with the module?
A: EnerVista UR Setup is a GE-licensed software product. We can advise on obtaining the correct version for your firmware, but software licenses must be obtained through GE Grid Solutions or authorized channels.
Q: What is the difference between UR8FH and UR6FH?
A: The primary difference is the chassis slot count and I/O capacity. The UR8FH is an 8-slot form factor offering greater I/O expansion, while the UR6FH is a 6-slot variant. Both share the same UR platform firmware and protection function library.
Q: Can this relay be used in a NERC CIP-compliant substation?
A: Yes. The UR series supports role-based access control, audit logging, and encrypted communications features required for NERC CIP compliance. Consult GE’s cybersecurity documentation for your specific CIP version requirements.
