GE F650 Multilin | High-Voltage Feeder Protection and Monitoring

Product Description

The GE Multilin F650-B-F-J-F1-G1-HI-6H-E is a high-performance feeder protection and bay controller designed for modern distribution systems. It delivers advanced protection against faults, supports feeder automation, and enables real-time monitoring. Moreover, the modular withdrawable case with flexible I/O simplifies installation and maintenance. In addition, integrated communication protocols including IEC 61850, Modbus, DNP3, and Ethernet TCP/IP ensure seamless system integration. Therefore, this relay provides accurate fault detection, adaptive reclosing, and operational efficiency for feeders ranging from 6.6 kV to 38 kV.
