Features:
- GE Multilin UR Series Revision 5.92 firmware release notes document
- Covers enhancements for line differential, motor protection, and communication protocols
- Essential reference for upgrading B30, B90, C70, D60, F60, G60, L90, M60, N60, T60 and other UR family relays
The URRHH provides essential technical documentation critical to the entire firmware upgrade process, serving as the authoritative reference for understanding changes between versions, directly affecting the proper, normal operation of the overall protection system. One URRHH document is required per firmware version, covering all affected UR products including B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, and T60 relays.
For applications requiring specific protocol improvements, the URRHH documents important changes to IEC61850 report control blocks and IEC60870-5-104 protocol implementation. In addition to standard release information, the URRHH includes critical details about the UR operating system debug port being modified to reject Ethernet traffic, enhancing cybersecurity.
The URRHH's comprehensive information ensures reliable firmware upgrades in demanding power system environments. Using detailed change categories including new features, enhancements, and product advisories, the document enables engineers to assess impact before deployment. The upgrade path information in the URRHH confirms that devices with firmware version 4.00 and above can be upgraded directly, while systems below 4.00 require special upgrade packages.
The URRHH GE Universal Relay may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Power Infrastructure: Widely deployed in utility substations, power generation plants, and transmission/distribution networks.
- Industrial Operations: Used in heavy industries such as oil and gas, mining, manufacturing, and process control.
- Specialized Monitoring: Supports relays that monitor up to six three-phase power circuits and provide PMU (Phasor Measurement Unit) data for grid stability.
- Dry Contact Support: Uniquely provides power not only to the relay itself but also to any external devices connected to its dry contact inputs.
- Form Factor: Typically installed as a plug-in module within a 19-inch rack horizontal mount unit.
- Wiring: Connects via the backplane of the UR series chassis, featuring a black matte finish for board protection.
- Software Management: Fully integrated with EnerVista UR Setup software for remote monitoring and configuration.
- Redundancy Requirements: If using a redundant power configuration, you must ensure both power modules are of the same type (e.g., both RH/RHH). Mixing different versions like RHH with SH or TH in a redundant setup can cause unpredictable system behavior.
- Temperature Range: Operates effectively between -20°C to +70°C.
- Storage Conditions: Can be safely stored in temperatures ranging from -40°C to +85°C.
- Rugged Construction: Features a robust industrial PCB and high-quality electronic components rated for Class I protection.
- Physical Durability: Newer iterations may include conformally coated circuit boards to withstand humidity and corrosive atmospheres common in industrial sites.
