369B1859G0021

369B1859G0021 is a GE Grid Solutions Industrial Protection & Control Module (also referred to as GE 369B1859G0021 Feeder Protection Relay Module, Medium-Voltage Power System Protection Module), a core safety and control component designed for GE’s industrial power protection systems, primarily used for medium-voltage (MV) feeder, transformer, and motor protection in power distribution networks.

The 369B1859G0021 module is a high-performance industrial protection and control module developed by GE Grid Solutions (a division of General Electric), a global leader in power system equipment and automation. Specifically engineered for medium-voltage power distribution networks (typically 4kV–35kV), its core functions include real-time monitoring of electrical parameters (current, voltage, frequency, power), fault detection (overcurrent, overvoltage, undervoltage, earth fault), and rapid protective actions (trip signal output, alarm activation) to prevent equipment damage 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 redundant communication interfaces. It offers flexible protection logic configuration to adapt to diverse application scenarios (feeder protection, transformer backup protection, motor overload protection) and supports seamless integration with SCADA systems and substation automation platforms via standard industrial protocols.

Widely deployed in industrial power plants, commercial buildings, data centers, and utility substations, the 369B1859G0021 module plays a critical role in enhancing the reliability, safety, and efficiency of medium-voltage power distribution systems, minimizing downtime caused by electrical faults and ensuring continuous power supply to critical loads.
