Description
Product Overview
The GE 350-E-P1-G1-H-E-S-C-P-2E-D-N is a high-performance feeder protection relay designed by GE Multilin, belonging to the advanced Multilin 3 Series platform. Engineered for medium to high voltage distribution systems, this relay delivers comprehensive protection, control, and monitoring for feeders, transformers, and capacitor banks in utility and industrial applications. Its modular design supports drawout or fixed mounting, making it suitable for both new installations and retrofitting existing switchgear.
Key functions include arc flash mitigation through zone inter-tripping and light sensor integration713, directional power protection, and thermal overload detection. The relay features programmable logic elements for custom control sequences, such as cold load pickup and autoreclose cycles13. With support for multiple communication protocols (IEC 61850, Modbus TCP/IP, DNP 3.0), it enables seamless integration into smart grid systems for real-time diagnostics and remote management714. The intuitive front-panel interface and configuration software simplify setup, while environmental monitoring tracks temperature and humidity to optimize maintenance schedules13.
