GE 369B1859G0022 Product Description
The GE 369B1859G0022 is a high-performance motor management relay engineered for mission-critical industrial applications, particularly in power generation, oil & gas, and heavy manufacturing. As part of GE’s renowned Multilin 369 series, this module delivers comprehensive protection, control, and monitoring for medium-voltage motors, ensuring optimal performance and minimizing downtime in harsh operating environments. It acts as a centralized hub for motor health management, integrating advanced diagnostic capabilities with user-friendly configuration tools to safeguard against faults while enabling predictive maintenance.
Designed for rugged reliability, the GE 369B1859G0022 supports a wide input voltage range (50–300 VDC or 60–265 VAC) and features a compact IP20-rated enclosure, making it suitable for indoor use in dusty or vibration-prone settings like turbine control rooms or refinery pump stations. Its modular design allows seamless integration into existing automation systems, providing real-time insights into motor parameters such as current, temperature, and vibration. By combining overcurrent protection (50P/50G), unbalance detection (46), and ground fault monitoring (50G), the relay mitigates risks of catastrophic failures, extending motor lifespan and reducing maintenance costs.
The GE 369B1859G0022 stands out for its versatility and precision. Its 12 RTD inputs support temperature monitoring of motor windings, bearings, and ambient conditions, enabling proactive thermal management. For example, during motor startup, the relay calculates thermal capacity using phase and unbalance current heating models, ensuring safe acceleration while preventing overheating. The built-in anti-backspin protection feature inhibits restart until the motor has decelerated to a safe speed, a critical safeguard in applications like conveyor systems or compressors where sudden reversals could cause mechanical damage.
Maintenance is simplified through front-panel LED indicators that provide real-time status updates for power, fault conditions, and communication links. The relay also stores event logs and fault waveforms, allowing engineers to diagnose issues remotely via GE’s
ToolboxST software. Additionally, its
redundant power inputs (24V DC and 120V AC) ensure continuous operation even during transient power fluctuations, a must-have for uninterruptible processes like gas turbine control.
The GE 369B1859G0022 excels in environments where motor reliability is non-negotiable:
- Power Generation: In combined-cycle power plants, it protects steam and gas turbine-driven pumps by monitoring bearing temperatures and detecting mechanical jams. For instance, during load changes, the relay ensures smooth transitions by adjusting motor torque limits dynamically.
- Oil & Gas: On offshore platforms, it safeguards subsea pump motors from saltwater corrosion and voltage surges, using surge protection (6 kV) to maintain signal integrity in high-humidity conditions.
- Manufacturing: In automotive assembly lines, the relay coordinates with PLCs to synchronize conveyor belt motors, preventing bottlenecks by enforcing starts-per-hour limits (66) and minimum time between starts.
- Water Treatment: It controls wastewater pumps, using undercurrent detection (37) to identify clogged impellers and trigger automatic shutdowns before damage occurs.

Installing the GE 369B1859G0022 requires a clean, dry control cabinet with adequate airflow. Secure it to a 35mm DIN rail using the included mounting clips, ensuring minimal vibration transfer. Proper grounding is critical—connect the module’s grounding terminal to the system’s main ground bus using 18 AWG conductors to reduce EMI.
For maintenance, perform quarterly inspections to:
- Clean dust from vents using compressed air.
- Verify tightness of terminal blocks (torque: 0.5–0.8 N·m).
- Use a multimeter to check input voltage stability.
While the relay is designed for 10+ years of service, replace the internal battery (for event log retention) every 5 years. In high-duty cycles, consider annual calibration using GE’s certified test equipment to ensure accuracy.
