GE F650 l Feeder Protection System

GE F650 l Feeder Protection System

High end features in an economical package. The F650, a member of the 650 Family of protection relays, is high performance digital device that incorporates protection, control, and metering in a economical package. Use the F650 to protect HV/MV feeders, bus couplers, transformers and capacitor banks. The F650 is the first feeder relay with remote I/O capabilities via the CIO module.

The F650, a member of the 650 Family of protection relays, incorporates protection, control, automation and metering in a economical package. F650 comes with a large LCD and single line diagrams can be built for bay monitoring and control for various feeder arrangements including ring-bus, double breaker or for breaker and half.


  • Primary or back-up protection and control for feeders on solidly grounded, high impedance grounded or resonant grounded systems
  • Bus blocking/Interlocking schemes
  • High-speed fault detection for arc flash
  • Throw over schemes (bus transfer scheme applications)
  • Load shedding schemes based on voltage and frequency elements
  • Back-up protection of high voltage applications
  • Distributed Generation (DG) interconnect protection, including active and passive anti-islanding

Key Benefits
