General Electric F650BFEF2G0HIC Versatile Feeder Protection Relay

The GE F650BFEF2G0HIC is a Versatile Feeder Protection Relay designed for industrial feeder protection and control. It offers a comprehensive suite of protection features, including instantaneous overcurrent (50SG), ground directional units (67G, 67N), thermal models (49), and sensitive ground protection for both primary and backup applications. The relay is equipped with advanced communication capabilities and high-precision settings to ensure quick, reliable, and accurate fault detection.
