The F-PRO 200 family of numerical multifunction relays provide complete feeder protection with a wide range of protection functions suitable for transmission, distribution and industrial applications. This broad selection of relay functionality and hardware options allow customers to choose the best suited and most cost-effective solution for each application. High reliability comes from robust and field-proven design, as well as self-monitoring hardware and a software watchdog.

All F-PRO relays include metering, sequence of event (SOE) reporting with 1 ms time stamp resolution, high quality oscillography waveform capture and fault log facility for analysis. The intuitive and simple Windows-based Relay Control Panel software allows easy configuration and disturbance analysis. Communication options supporting serial and Ethernet interfaces, as well as multiple protocols, allow simplified system integration with substation control and SCADA systems.


  • Primary and back-up current, voltage and frequency protection for transmission and distribution equipment
  • Load shedding schemes based on frequency and rate-of-change of frequency elements
  • Restricted and sensitive earth fault protection
  • Two-stage breaker failure protection and breaker condition monitoring
  • Busbar protection for low voltage levels can be realized by interlocking schemes
