Description
Product Overview
The GE Multilin 369-HI-R-M-0-0-0-E combines motor protection, measurement, temperature monitoring, and diagnostic recording in a single digital relay. It is intended for industrial AC motor applications where overloads, phase-current abnormalities, ground faults, excessive starting conditions, or motor temperature excursions need to be detected and acted on. Protection functions depend on the relay settings and the characteristics of the motor and installation; correct commissioning requires motor nameplate data and coordinated protection settings.
The R option adds 12 built-in RTD inputs for temperature monitoring, while the M option adds the metering package. The final E denotes the enhanced faceplate and diagnostic feature set, including motor health reporting, learned data, start-data logging, enhanced event recording, and security audit-trail events. These functions can help maintenance personnel investigate trips and compare motor operating behavior over time.
For procurement and replacement planning, the full order code matters. This version has the HI control-power range and does not specify optional fiber-optic or fieldbus protocol interfaces. Do not assume it has PROFIBUS, DeviceNet, or Modbus/TCP simply because other Multilin 369 configurations offer those options. Before installation, verify the existing relay’s wiring, CT secondary rating, RTD type, trip and alarm assignments, control supply, and stored configuration. A replacement should be commissioned and tested against the site’s approved motor-protection settings.
Product Introduction
The GE Multilin 369-HI-R-M-0-0-0-E is a configurable motor management relay for industrial motor control and protection panels. Its option code identifies high-range control power, built-in RTD inputs, metering capability, and enhanced diagnostics.
The relay is available in a non-drawout design, according to the manufacturer’s instruction manual. When replacing an installed unit, verify the panel cutout and mounting arrangement, terminal wiring, CT connections, control supply, RTD wiring, and configuration compatibility before returning the motor to service.

Frequently Asked Questions
Q1: What is the GE Multilin 369-HI-R-M-0-0-0-E used for?
It protects and monitors industrial AC motors, combining electrical protection functions with metering, temperature monitoring, and enhanced diagnostic recording.
Q2: What does HI mean in the model number?
It specifies the high-range control supply: 50–300 VDC or 60–265 VAC at 50/60 Hz. Confirm the actual supply against the unit label and installation design.
Q3: What do the R and M options provide?
R indicates 12 built-in RTD inputs for motor temperature monitoring. M indicates the metering package, which adds measurement capabilities beyond the base configuration.
Q4: Does this model include PROFIBUS or DeviceNet?
The three 0 option fields indicate that no optional protocol interface, fiber-optic port, or harsh-environment option is specified in this order code. Do not assume optional PROFIBUS, DeviceNet, or Modbus/TCP hardware is installed.
Q5: What does the final E indicate?
It indicates enhanced diagnostics and the enhanced faceplate. Published functions include motor health reporting, enhanced learned data, motor-start data logging, enhanced event recording, and security audit-trail events.
Q6: What should be checked before replacing the relay?
Verify the full order code, control-power range, CT secondary rating, RTD sensor types and wiring, trip outputs, alarm assignments, and stored protection settings. Confirm that the replacement’s optional hardware matches the existing system.
Q7: How should a used relay be evaluated?
Request photographs of the nameplate and terminals, confirmation of the exact option code, evidence of power-up and functional testing, and details of any previous repairs. Before operation, load or verify the approved settings and perform the required protection and trip-circuit tests.
