The F650 ordering guide defines separate options for display, communication boards, I/O boards, and auxiliary supply. The HI supply range should not be taken as proof of the full configuration.
Application Scenarios & Pain Points
Protection relay replacement is not just a hardware swap. An incorrect pickup setting, incompatible communication board, or miswired current transformer can delay fault clearance or create unwanted trips.
Typical applications
- Distribution substations: Feeder overcurrent protection, breaker control, and fault-event analysis.
- Industrial power distribution: Monitoring electrical measurements and coordinating configured trip logic.
- Switchgear modernization: Replacing legacy F650 equipment while retaining the approved protection scheme and compatible wiring.
- Remote substation monitoring: Communicating relay status and event information to supervisory systems using supported interfaces and protocols.
Field note: Before removing the original unit, save the relay settings and record CT/VT ratios, trip contacts, communication addresses, and output assignments. After installation, validate the protection settings and trip circuit under the site’s approved commissioning procedure.

The Engineer’s Guide: Field Pitfalls to Avoid
Warning 1 — Misreading the ordering code
- Compare the full model number on the relay label with the purchase specification.
- Verify display, communication boards, I/O slots, and auxiliary supply independently.
- Resolve the unexplained
6in the suppliedHI6Esegment before ordering a replacement.
Warning 2 — Incorrect CT/VT wiring or settings
- Record CT and VT ratios, polarity, and phase sequence.
- Confirm protection pickup values, time delays, and directional settings.
- Perform approved secondary-injection and trip-circuit tests before returning the feeder to service.
Warning 3 — Firmware and communication mismatch
- Check the hardware revision and supported firmware.
- Verify the required EnerVista 650 Setup version for the installed firmware.
- Confirm protocol support, network settings, event reporting, and communication with the station control system. GE publishes firmware and configuration resources by release, so version compatibility matters.
Frequently Asked Questions (FAQ)
1. What is the GE F650BFGF2G1HI6E used for?
It belongs to the GE Multilin feeder protection and digital bay controller family. The platform provides configurable electrical protection, breaker control, metering, and substation automation functions. The exact options associated with this specific string require confirmation.
2. What does the HI auxiliary supply option mean?
For documented configurations, HI indicates an auxiliary supply range of 110–250 V DC or 120–230 V AC. Verify the nameplate and applicable hardware documentation before connecting station power.
3. Can I replace this unit with another relay?
Only after confirming the complete ordering code. Differences in communication boards, digital I/O, display options, firmware, and auxiliary supply can affect installation and operation. The protection settings and trip logic must also be validated.
4. How do I confirm the exact model configuration?
Read the complete nameplate and compare every option against the OEM ordering guide. Record the display type, communication boards, I/O board selections, auxiliary supply, and hardware revision. In this case, specifically confirm whether the 6 in HI6E is part of the correct designation.
5. What tests should be requested for a refurbished ?
Request a documented inspection and functional test covering power-up diagnostics, display operation, communication, input measurement, output contacts, and event recording where applicable. For protection-critical installations, complete site-approved secondary-injection and trip-circuit commissioning tests.
6. How can I verify firmware compatibility?
Identify the relay’s hardware revision and installed firmware, then check the corresponding GE release notes and configuration software requirements. Do not assume a newer firmware package is suitable for every hardware revision.
7. What should I confirm before purchasing this relay for an outage?
Obtain written confirmation of the complete part number, auxiliary supply, I/O configuration, communication options, stock condition, testing performed, warranty, and dispatch date. If the exact code remains unresolved, ask for a clear nameplate photograph before releasing the purchase order.
