Description
Technical Architecture & Functional Positioning
The F650CFBF1G0HI10NBA is the most widely deployed F650 variant, offering the complete protection and automation feature set of the platform while reducing digital I/O to the exact quantity required for typical MV feeder and incoming breaker applications. This eliminates the cost of unused contacts found in higher I/O models (e.g., the “2G” version).
GE retained the identical dual-processor architecture (DSP for protection, ARM for communication and logic) and the full FlexLogic™ engine, so there is zero compromise on protection speed, GOOSE performance, or custom scheme capability. Trip times remain sub-cycle (<12 ms) for close-in faults, and the relay can exchange hundreds of GOOSE messages per second without affecting deterministic protection.
This configuration is the sweet spot for utilities and industries that need modern IEC 61850 communication, full reclosing, and advanced monitoring but rarely require more than 16 inputs or 8 outputs per bay.
Typical Application Scenarios
- Primary distribution feeder protection in 11–36 kV municipal and rural networks
- Industrial plant main incoming and critical feeder protection with automatic transfer schemes
- Compact secondary substations and ring-main units where panel space and cost are constrained
- Retrofit of legacy static or first-generation digital relays (SPCR, KAVR, MFAC) with minimal rewiring
- Wind and solar farm collector feeder protection with integrated fault ride-through logic
Quality Standards & Testing Procedures
Every F650CFBF1G0HI10NBA undergoes a 72-hour hardware-in-the-loop acceptance cycle on our Omicron CMC-356 + RTDS platform.
