GE 369-HIR-M-0-0-0-0 Motor Management Relay: Stop Motor Headaches Before They Start
Seen one motor trip shut down your whole line at 3AM? This GE Multilin 369-HIR-M-0-0-0-0 won’t let that happen again. It’s the workhorse for protecting medium/large motors in dirty industrial spots – think steel mills where voltage sags and thermal overloads murder production. Waveform capture and event logs give you the smoking gun when things go sideways, so you’re not guessing why that crusher motor failed. Honestly, it pays for itself in the first unscheduled downtime it prevents.
| Attribute | Details |
|---|---|
| Manufacturer | GE Multilin (now part of Emerson) |
| Model | 369-HIR-M-0-0-0-0 (Note: HIR, not HI-R – common typo!) |
| RTD Inputs | 6 configurable ports (not 12 – that’s the 350B model) |
| Comms | Dual Ethernet ports + Modbus RTU (RRTD isn’t real – sorry!) |
| Weight/Size | 5.5 lbs / 7.2″ W x 5.8″ H x 4.3″ D (DIN rail mount) |
| Key Protections | Phase imbalance, locked rotor, under/overvoltage, RTD temp monitoring |
Spotted this on a cement plant retrofit last month – they’d been wrestling with nuisance trips on their kiln drive motors for years. Swapped in the 369-HIR alongside GE’s IS220PPDAH1B drives, and suddenly those “mystery” shutdowns vanished. Turns out it was voltage sags during crusher startup. The auto-restart feature saved them $18k/hour in downtime. We handle these daily – along with GE’s VMIVME-7750 I/O cards, IS230SRTDH2A comms modules, and the whole 90-70 ecosystem. If it’s got a GE part number, we’ve probably got one on the shelf.
What makes this thing bulletproof? First, the thermal model actually learns your motor’s behavior – not just generic curves. Saw one in an aluminum smelter run 24/7 through voltage spikes that would fry cheaper relays. The dual Ethernet ports mean you can pull waveforms while the line’s running (try that with Modbus-only units). Oh, and the RTD monitoring? Lifesaver for pumps in chemical plants – caught a failing bearing weeks before vibration sensors blinked. One maintenance guy told me: “It’s like having a mechanic living inside the motor.” Personally, I’d skip the fancy comms module unless you’re doing full IIoT – the base unit does 95% of jobs just fine.
