Product Introduction
GE Multilin 369-HI-R-M-0-0-H-E is a full-option motor management relay for critical three-phase AC motors. It combines adaptive thermal overload, phase loss, unbalance, ground-fault, jam/stall, and RTD-based temperature protection with true-RMS electrical metering.
This build adds 12 RTD inputs, a metering package, Ethernet communications, and enhanced diagnostics. Control power runs 50-300 VDC or 60-265 VAC, making it suitable for both DC UPS-fed panels and standard AC auxiliary supplies.

Quality Control Process (DYNAMIC GENERATION)
- Front-panel and display verification. We check the LCD, keypad, status LEDs, and motor/output indicators for full functionality.
- Control power-up test. The relay is energized at both AC and DC rated levels to confirm stable boot, self-test pass, and no nuisance trips.
- RTD channel check. Each of the 12 RTD inputs is tested with known resistance values to confirm accurate temperature reading and proper alarm/trip thresholds.
- CT and metering validation. We inject secondary current and voltage signals to verify phase current, ground-fault sensing, and metering accuracy for V, A, kW, kVAR, and PF.
- Communication and relay output test. RS485 Modbus RTU and Ethernet Modbus TCP are verified for connectivity, and each output relay is pulsed under load. The unit is then anti-static bagged and foam-packed.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Verify the full option code before swapping. The 369-HI-R-M-0-0-H-E includes RTD inputs, metering, Ethernet, and enhanced diagnostics. A base 369 without R, M, or E will not support the same setpoints or wiring.
❗ RTD wiring must use shielded cable. Unshielded RTD runs in MCC environments pick up noise and can cause false temperature trips. Ground the shield at the relay end only.
❗ Ethernet and RS485 addresses must be reconfirmed. A new relay ships with default communication settings. If the old unit had a custom IP address, Modbus ID, or baud rate, the replacement will not communicate until reconfigured.
❗ Do not exceed CT secondary ratings. Mixing 1 A and 5 A CTs or programming the wrong ratio will cause incorrect thermal model calculations and false overload trips.
Keep these in mind and you’ll cut 90% of rework time.
