F-PRO Feeder Protection & Management Relays


F-PRO 216: Non-Directional Over Current Protection Relay with SEF F-PRO 235: Directional Multifunction Protection Relay

Categories : Relays


The F-PRO 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.

The 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.
