The GE 369-LO-0-M-F-E-0-0 Motor Management Relay is a digital protective relay designed for advanced motor control and protection in industrial applications.
Its key functions include:
1. Comprehensive Motor Protection
Detects and mitigates faults such as overload, current imbalance, phase loss, ground faults, and locked rotor conditions using adaptive protection algorithms.
Supports 15 standard thermal curves and user-defined FlexCurve™ profiles for precise motor thermal modeling.
2. Real-Time Monitoring & Diagnostics
Monitors current, voltage, power, and temperature (via connected sensors) to prevent overheating and mechanical stress.
Records event logs, fault data, and motor start-up parameters for predictive maintenance and troubleshooting.
3. Adaptive Motor Learning
Automatically “learns” motor parameters (e.g., inrush current, cooling rates) to optimize protection settings for specific applications.
Suitable for dual-speed motors and complex mechanical systems.
4. Communication & Control
Features RS232 (front panel) and RS485 (rear ports) with Modbus RTU protocol for SCADA/DCS integration.
Provides analog outputs (4-20mA) and digital I/O for external control systems.
5. Enhanced Reliability Features
Includes communication loss trip and undervoltage auto-restart functions for system stability.
Rated for 20-60VDC or 20-48VAC control power, designed for harsh industrial environments.
