F650 Digital Feeder Relay | GE Multilin High-Voltage Controller

Product Description

The GE Multilin F650 Digital Bay Controller (F650BABF2G1HI) delivers advanced feeder protection and automation for modern distribution networks. Designed for line protection, arc flash mitigation, and adaptive reclosing, this relay ensures reliable power system performance. Moreover, its modular, withdrawable hardware with flexible I/O and a user-friendly front panel provides both convenience and operational efficiency. In addition, integrated communication protocols such as IEC 61850, Modbus, and DNP3 enable seamless connectivity with modern SCADA and automation systems. Therefore, the F650 relay offers superior protection, precise fault detection, and complete operational visibility for medium- and high-voltage feeders.
