369-HI-0-M-F-E-0
Product Name
369-HI-0-M-F-E-0 is a GE Multilin 369 Feeder Protection Relay Module (also referred to as GE 369-HI-0-M-F-E-0 Medium-Voltage Industrial Protection & Control Module, Multilin 369 High-Integrity Feeder Protection Relay), a core safety component designed for medium-voltage (MV) power distribution systems to protect feeders, transformers, and motors from electrical faults.
2. Product Description
The 369-HI-0-M-F-E-0 module is a high-integrity feeder protection relay developed by GE Multilin (a division of GE Grid Solutions), engineered specifically for medium-voltage power distribution networks (typically 4kV–35kV) in industrial plants, utility substations, data centers, and commercial buildings. Its primary function is to monitor electrical parameters (current, voltage, frequency, power), detect faults (overcurrent, overvoltage, undervoltage, earth fault, phase imbalance), and initiate rapid protective actions (trip signals, alarms) to prevent equipment damage, minimize downtime, and ensure grid stability.
Featuring a rugged industrial design optimized for harsh power system environments, the module integrates advanced microprocessor technology, high-precision signal acquisition circuits, and flexible communication interfaces. The model suffix “HI” denotes “High Integrity,” indicating compliance with strict reliability standards for critical applications. It supports customizable protection logic via GE’s EnerVista software, enabling adaptation to diverse application scenarios (feeder protection, transformer backup protection, motor overload protection). Additionally, the module offers seamless integration with SCADA systems and substation automation platforms via standard industrial protocols, facilitating remote monitoring, control, and data analysis.
Widely deployed in safety-critical power distribution systems, the 369-HI-0-M-F-E-0 module plays a pivotal role in enhancing the reliability, safety, and efficiency of medium-voltage networks, ensuring continuous power supply to critical loads while mitigating risks associated with electrical faults.
