The GE Multilin 750-P5-G5-S5-HI-A20-G-E Feeder Management Relay is a digital relay intended for the management and primary protection and control of distribution feeders. The 750-P5-G5-S5-HI-A20-G-E provides comprehensive protection functions for feeders and backup protection for bus, transformers, and transmission lines in a draw-out construction. Equipment capabilities include phase, neutral, ground, and sensitive ground overcurrent protection, voltage and frequency monitoring, along with directional overcurrent control elements. The unit features 5 A phase current inputs, 5 A ground current inputs, a 5 A sensitive ground current input, high-range control power, eight 4–20 mA analog outputs, a green breaker closed LED, and an enhanced display with a 10BaseT Ethernet option. Integrated networking interfaces support ModBus RTU, DNP 3.0 Level 2, and ModBus RTU over TCP/IP protocols to interface with SCADA, DCS, or PLC systems.
