GE Multilin 369-HI-R-M-0-0-0-H-E Motor Management Relay

Product Brief Description

The GE Multilin 369-HI-R-M-0-0-0-H-E is a 369 series integrated motor protection and management relay, built for medium voltage and large low-voltage three-phase AC motors. It combines full motor protection, precise metering, condition monitoring, control and event recording into one compact panel-mount unit. Featuring a patented thermal model, locked rotor and backspin protection, this relay supports multiple communication protocols and RTD temperature monitoring. It is widely used in water, oil & gas, chemical, mining and power plant critical motor circuits to prevent unexpected motor damage and reduce unplanned downtime.

Product Functions

• Comprehensive motor protection: overload thermal protection, locked rotor/stall protection, phase loss, phase reversal, overcurrent, ground fault and undervoltage protection
• Real-time motor temperature monitoring via RTD inputs for bearing and stator overtemperature alarm and trip
• Accurate electrical metering of current, voltage, power, power factor and motor start characteristic recording
• Built-in event sequence logging, fault oscillography and motor health report for post-fault analysis and predictive maintenance
• Programmable control logic, breaker/contact control, alarm outputs and configurable digital I/O for motor control interlocks
• Multiple communication interfaces including RS485 Modbus, optional Ethernet; supports EnerVista software for setup and diagnostics

Application Scenarios

• Medium voltage pump, fan and compressor motor protection in power plants and water treatment facilities
• Oil & gas, chemical and mining critical process motor control and safety supervision systems
• Submersible downhole pump motors with backspin protection requirements
• Industrial plant large low-voltage motor protection and asset monitoring
• Retrofit replacement projects for legacy GE 369 motor protection relays
