350-C-P5-G5-H-S-M-N-P-SN-D-N | GE Fanuc | Feeder Protection Relay

Description

The 350-C-P5-G5-H-S-M-N-P-SN-D-N | GE Fanuc Feeder Protection Relay is a specialized digital protection device for power distribution systems. While direct technical data for this exact model is unavailable, comparable GE Fanuc feeder protection relays offer robust performance aligned with industry standards. Similar units, such as the SR750 series, operate at 220V and support output frequencies up to 660. Core features mirror those of the GE Multilin 750/760 feeder protection system, which provides primary protection and control for distribution feeders in solidly grounded, high-impedance grounded, or resonant (Peterson coil) grounded systems. Key capabilities include bus blocking/interlocking schemes, high-speed fault detection for arc flash mitigation, and load shedding solutions based on voltage and frequency parameters. These relays also deliver backup protection for transmission lines, feeders, and transformers, plus distributed generation (DG) interconnection protection. Programmable elements include two phase time-overcurrent (TOC) components with level detectors, two overcurrent elements for primary and backup use, selectable 15 curve shapes (including FlexCurves), curve multipliers, and adjustable pickup current levels for trip, alarm, or control functions. Optional conformal coating is available for operation in chemically corrosive or high-humidity environments, ensuring extended service life and compliance with international standards.
