Overview
The GE Multilin 350-E-P5-G5-H-E-M-N-P-SN-P-N Feeder Protection System is a microprocessor-based relay built to protect, control, and monitor electrical feeders in demanding environments. It supports both primary and backup protection roles, making it suitable for utility substations, industrial power systems, and renewable energy installations.
Moreover, this model includes integrated arc flash protection, advanced metering, and diagnostic capabilities. Its draw-out chassis design simplifies installation and maintenance, while multiple communication protocols—including Modbus, DNP3, and optional Ethernet—enable seamless integration with SCADA and automation platforms. In addition to standard protection features, the relay supports preventative maintenance strategies through event recording and waveform capture.
Therefore, this relay is ideal for facilities requiring high-speed fault detection, flexible control logic, and secure remote access.
