GE Multilin F650-F650BFBF2G0HIE – Feeder Protection Relay for Distribution & Industrial Networks
The GE Multilin F650 series is a solid, field-proven relay platform for medium-voltage feeder protection, automation, and control. The configuration F650-F650BFBF2G0HIE appears to be a high-feature build that typically includes Ethernet communications and advanced protection elements. From my experience, teams choose the F650 when they need dependable feeder protection with IEC 61850, flexible I/O, and straightforward commissioning using EnerVista software.

Application Fields
You’ll usually see F650 relays on MV feeders, ring mains, and transformer secondaries where selective protection and fast comms matter. Typical scenarios include:
- Utility substations – Feeder protection with IEC 61850 station bus and gateway integration
- Industrial plants – Process feeders, MCC incomers, and main tie-main schemes
- Oil & gas and mining – Harsh environments needing robust protection and powerful logic
- Data centers and campuses – Selective coordination, transfer schemes, event records for compliance
- Renewables & microgrids – Intertie and feeder protection with remote monitoring
Advantages & Value
- Reliability in real grids – The F650 platform has a long track record; it typically shrugs off substation noise and transient events.
- Protocol flexibility – Native IEC 61850 plus Modbus/DNP3 reduces gateway hardware and engineering hours.
- Lower lifecycle cost – Draw-out design and clear event records cut troubleshooting time and outage duration.
- Compatibility – 1 A/5 A CT compatibility and standard VT ratings make retrofits smoother with legacy switchgear.
- Support ecosystem – EnerVista tooling, firmware maintainability, and widely available spares help keep assets online.
Installation & Maintenance
- Panel & environment: Install in a clean, dry, ventilated panel. Maintain clearance for convection and cable bend radius. Avoid direct sunlight and strong vibration.
- Wiring practices: Observe CT polarity, short CTs before maintenance, and segregate low-level signals from high-voltage/control circuits. Use shielded twisted pairs for comms.
- Grounding: Bond chassis and reference grounds properly; star-grounding reduces nuisance trips in many cases.
- Settings & testing: Manage settings with EnerVista 650 Setup; keep a controlled settings library with version history. Secondary injection test after commissioning.
- Routine maintenance: Periodically review event logs, clean terminal areas, verify time sync, and check firmware release notes for stability/security updates.
- Safety: Follow lockout/tagout procedures. Verify CT circuits are shorted before removing the draw-out case.
Quality & Certifications
- Typically complies with CE and UL/cUL for protective relays
- RoHS alignment on electronic assemblies in most configurations
- Manufacturer quality systems commonly certified to ISO 9001
- Standard warranty support: 12 months; our sales warranty is 365 days
Common Accessories & Supporting Components
Depending on your build code, the following accessories are often paired with F650 relays:
- Flush-mount panel kit and gasket, rear terminal covers
- Front test plug and test lead set for secondary injection
- RS‑485 to USB interface cable for local setup
- Ethernet redundancy modules and patch cords for substation networks
- Time sync wiring for IRIG‑B or SNTP configurations
One thing I appreciate is how quickly commissioning goes when settings are organized. A utility client recently swapped an older feeder relay for an F650 and, thanks to pre-tested logic and 61850 templates, cut their planned outage window by almost half. You might notice the same effect if you standardize on this platform.
