The GE 369-HI-R-0-0-0-0-E is a microcomputer-based, digital protection and monitoring relay engineered to manage three-phase medium-sized AC motors and their driven mechanical hardware assets. Operating as an adaptive safety device, the unit proactively learns individual motor starting and historical running characteristics to dynamically adjust its internal protection profiles. This specific model prefix breakdown indicates a "HI" broad-range control power configuration paired with the "R" option, which adds 12 independent, programmable Resistance Temperature Detector (RTD) input links directly to the chassis.

n Control Supply Power Voltage (HI Option): 50 to 300 VDC or 60 to 265 VAC

n Phase and Ground CT Inputs: 1 A or 5 A secondary rating configurations

n Analog Outputs: 1 channel standard with the base unit, configurable for 0-20 mA or 4-20 mA current loops

n Output Relay Contact Rating: 10 A continuous rating

n Ambient Operating Temperature: -40°C to +60°C (-40°F to +140°F) continuous cabinet environment rating

n Ambient Storage Temperature Range: -40°C to +80°C

n Relative Operating Humidity: Up to 95% (Non-condensing state)

1.

Medium-Voltage AC Motor Protection: Wired directly to a medium-sized asynchronous machine inside a factory control panel. It constantly samples three-phase current profiles to track running conditions, and if it senses locked rotor states or sudden phase unbalances, it triggers an immediate circuit breaker trip.

2.

Mining & Metal Ore Processing: Installed inside heavy processing mills to monitor the stator, bearing, and ambient temperatures of high-torque conveyor motors, grinding mills, and material transport tracks.

3.

Oil, Gas, & Refining Infrastructures: Managed on high-pressure fluid transfer pump networks, refinery ventilation fans, and remote pipeline extraction systems to enforce safe start inhibits and execute motor cool-down time parameters.

4.

Pulp, Paper, & Chemical Batch Facilities: Regulates electrical thermal model protection for large batch mixing motors, heavy-duty chippers, and water-treatment supply pumps where single-point motor burnout failures would freeze production lines.
