GE 269P-D’O-278-100P-HI Motor Protection Relay | Multilin 269 Plus Series
Engineering Background
The GE Multilin 269 Plus series represents General Electric’s flagship platform for medium-voltage motor protection in industrial environments. Designed for demanding continuous-duty applications, the 269P integrates comprehensive protection functions—thermal overload, phase unbalance, ground fault, and jam detection—into a single DIN-rail or panel-mount unit. The 269P-D’O-278-100P-HI variant is factory-configured for 100 A CT input with high-speed trip output, making it the preferred choice for critical motor assets in process industries.
Product Positioning
Konmask.com sources this relay directly from verified OEM channels and authorized distributors. Each unit undergoes incoming inspection against GE factory documentation before listing. This SKU is stocked to support MRO procurement, capital project builds, and emergency replacement scenarios where lead time from the OEM is unacceptable.

Proven Application Environments
- Medium-voltage motor control centers (MCC) in oil & gas upstream and downstream facilities
- Pump and compressor protection in water treatment and chemical processing plants
- Conveyor and crusher motor protection in mining and mineral processing
- HVAC and chiller plant motor protection in commercial and industrial buildings
- Pulp & paper mill drive protection requiring drawout relay configurations
- Power generation auxiliary motor protection (BOP systems)
Engineering Advantages
- Drawout (D’O) Chassis: Enables hot-swap replacement without de-energizing the MCC bucket, minimizing process downtime during maintenance windows.
- High-Speed Trip Output: Sub-cycle trip response protects motor windings from catastrophic thermal damage during locked-rotor or fault conditions.
- 100 A CT Compatibility: Directly interfaces with standard 100:5 A metering-class CTs without auxiliary interposing transformers.
- Integrated Multifunction Protection: Eliminates the need for separate overload relays, ground fault relays, and thermistor monitors—reducing panel real estate and wiring complexity.
- Modbus RTU Interface: Enables integration with SCADA, DCS, and PLC systems for remote monitoring, event logging, and parameter adjustment.
- Proven Field Reliability: 269 Plus platform has accumulated millions of operating hours across global industrial installations since its introduction.
System Architecture & Signal Flow
The 269P-D’O-278-100P-HI operates as a standalone protection IED within the motor feeder circuit. Current signals from the 100 A CT are fed into the relay’s analog input stage, where they are digitized and processed by the internal DSP. The relay continuously computes thermal capacity used (TCU), phase unbalance percentage, and ground fault current. Upon detection of a protection threshold violation, the high-speed trip output energizes the associated contactor or circuit breaker trip coil within the configured time delay. Simultaneously, the relay logs the event with a time-stamp and fault type to its internal memory, accessible via the front-panel HMI or Modbus RTU port for post-fault analysis.

Technical FAQ
Q: Is the 269P-D’O-278-100P-HI compatible with the standard 269 Plus drawout chassis?
A: Yes. The D’O suffix designates the drawout mechanical configuration, which is compatible with GE Multilin standard 269 Plus drawout cradles used in most OEM MCC assemblies.
Q: What is the difference between the HI and LO trip output options?
A: The HI (high-speed) trip output provides faster operate time for applications requiring rapid fault clearance. The LO option provides standard-speed trip output. Consult the GE Multilin 269 Plus instruction manual (GEK-106288) for detailed timing specifications.
Q: Can this relay communicate with a Siemens or Rockwell PLC via Modbus?
A: Yes. The RS-485 Modbus RTU interface is vendor-agnostic and compatible with any PLC or DCS platform supporting Modbus RTU master functionality, including Siemens S7, Allen-Bradley ControlLogix, and Schneider Modicon series.
Q: What CT ratio should be used with the 100P variant?
A: The 100P designates a 100 A primary CT rating. Use a 100:5 A metering-class CT. Verify CT burden rating is within the relay’s specified input impedance range per the GE Multilin datasheet.
Q: Do you provide a warranty?
A: Yes. Konmask provides a 90-day functional warranty on all units. Extended warranty options are available—contact support for details.
