GE 369-HI-R-0-0-0-E – Multilin 369 Motor Management Relay
Product Overview
The GE 369-HI-R-0-0-0-E is a microprocessor-based digital motor management relay from GE Multilin’s respected 369 series-. Designed specifically for three-phase medium and large industrial motors, this relay delivers comprehensive protection, real-time monitoring, and diagnostic control in a single compact unit-.
What sets the 369 platform apart is its adaptive learning capability—during commissioning, the relay automatically learns the motor’s unique thermal and electrical characteristics, then tailors its protection curves accordingly-. The 369-HI-R-0-0-0-E variant adds enhanced diagnostics and an upgraded graphical interface, making it particularly well-suited for critical motor applications in oil and gas, mining, power generation, water treatment, and metals processing–3.
The relay integrates protection, metering, and communications into a rugged housing rated for harsh industrial environments-2. With 12 built-in RTD inputs for precise thermal monitoring, Modbus RTU connectivity, and 256-cycle waveform capture for forensic fault analysis, the 369-HI-R-0-0-0-E gives maintenance teams the visibility they need to prevent unplanned downtime and extend motor life–3.

Key Features and Benefits
Adaptive Motor Protection – The relay learns individual motor parameters—cooling rates, inrush current, and thermal characteristics—during initial startup, then automatically configures overload curves and protection setpoints for each specific application-.
12 Built-in RTD Inputs – Monitor stator winding and bearing temperatures directly without external temperature transmitters. The relay integrates RTD data into its thermal model for more accurate overload protection–2.
Enhanced Diagnostics & Faceplate – The “E” suffix brings an upgraded graphical display, motor health reporting, startup data logging, event records, and a security audit trail—all accessible directly from the front panel-1-2-10.
Waveform Capture – Stores up to 256 cycles of current and voltage waveform data for detailed post-fault analysis, helping engineers pinpoint the root cause of trips and plan corrective maintenance–3-5.
FlexCurve™ Overload – Choose from 15 standard curves or create custom overload profiles to match the thermal limits of your specific motor-10.
Ruggedized Construction – A conformal coating protects internal electronics from moisture, dust, and corrosive atmospheres, while the flame-retardant metal case ensures durability in demanding industrial settings-1.

Installation and Maintenance
The 369-HI-R-0-0-0-E mounts in a standard panel cutout or rack enclosure. The front panel provides IP40 protection, while the rear terminals are rated IP20-3. Mount the relay away from strong magnetic fields or high-current conductors to prevent interference-1.
Communication setup is straightforward via the front-panel RS-232 port for local configuration using GE’s EnerVista 369 software, or via the RS-485 port for integration into SCADA and DCS networks using Modbus RTU protocol-5-10.
The relay requires no routine maintenance beyond periodic visual inspection. With an MTBF exceeding 50,000 hours and a 12-month manufacturer’s warranty, the 369-HI-R-0-0-0-E delivers reliable service life in continuous 24/7 operations-2. For critical spares inventory, this model remains widely available through GE’s authorized distribution network and aftermarket suppliers.
