Product Description

The GE Multilin 350-E-P5-G5-H-E-M-N-P-SN-P-N is a member of the renowned Multilin 3 Series, specifically engineered to provide comprehensive protection, control, and monitoring for feeder applications in medium to high-voltage industrial and utility environments. This advanced protection system combines cost-effective hardware with field-proven algorithms to prevent false trips while ensuring rapid response to actual fault conditions.

This high-specification model features a multi-shot recloser, cold load pickup, and multiple setting groups, making it highly adaptable to varying load conditions. It excels in data management with extensive oscillography buffers and high-speed USB data transfer for post-fault analysis. Designed for global deployment, it operates reliably in extreme temperatures ranging from -40°C to +70°C and supports industry-standard protocols including Modbus RTU and DNP 3.0.
