Proven Application Environments
- Oil & Gas: Pump motor protection on offshore platforms and onshore processing facilities where HI sensitivity ground fault detection is mandatory for personnel safety.
- Mining & Minerals: Conveyor drive and crusher motor management in high-dust environments requiring robust thermal modeling and jam protection.
- Water & Wastewater: Submersible pump and blower motor protection with undercurrent detection for dry-run prevention.
- Pulp & Paper / Chemical Plants: Continuous process motors where unplanned downtime is critical — thermal capacity tracking enables predictive maintenance scheduling.
- Power Generation: Auxiliary motor protection in power plants where 216V AC control bus is standard.
- Marine & Offshore: Compliant with harsh environment requirements; CE marking supports EU/international vessel installations.
Engineering Advantages
- Precise Variant Matching: The 216V / 100P / HI configuration is factory-set — no field jumper changes or firmware reconfiguration required for matching installations.
- High-Sensitivity Ground Fault (HI): Detects ground fault currents as low as 0.2A (secondary), critical for high-resistance grounded systems common in North American industrial plants.
- Thermal Memory: Retains thermal capacity used (%TCU) through power loss, preventing premature restart after a trip — protecting motor windings from cumulative thermal damage.
- Starts-Per-Hour Limiting: Programmable start inhibit based on number of starts and thermal state — extends motor service life in high-cycle applications.
- Modbus RTU Integration: Enables SCADA/DCS integration for remote monitoring, event logging, and predictive maintenance data extraction.
- Proven Platform Longevity: 269 Plus is a mature, widely deployed platform with extensive field history — spare parts, documentation, and trained technicians are globally available.
System Architecture & Signal Flow
The GE269PLUS-D/O-216-100P-HI operates as follows in a typical motor protection scheme:
- Current Sensing: Phase currents are measured via external 100:5A CTs wired to the relay’s phase CT inputs. Ground current is measured via a dedicated ground CT or core-balance CT (HI sensitivity input).
- Signal Processing: The microprocessor samples all current inputs at high frequency, computing RMS values, thermal model state, and symmetrical components for unbalance detection.
- Protection Logic: Programmable pickup levels and time-delay curves are evaluated continuously. On fault detection, the relay asserts the appropriate output contact (trip, alarm, or auxiliary).
- Output Contacts (D/O): Digital output relay contacts drive the motor contactor or circuit breaker trip coil. Separate alarm contacts can signal the DCS or annunciator panel.
- Control Power: The 216V AC supply powers the relay’s internal logic and display — ensure the control transformer secondary matches this voltage before installation.
- Communication Bus: RS-485 Modbus RTU port connects to the plant SCADA system for real-time metering data, event records, and remote setpoint adjustment.

Technical FAQ
Q: What is the difference between the HI and LO ground fault sensitivity options?
A: The HI (High Sensitivity) version detects ground fault currents as low as 0.2A secondary, suitable for high-resistance grounded or ungrounded systems. The LO version has a higher pickup threshold, typically used on solidly grounded systems where nuisance tripping from leakage currents is a concern.
Q: Can the 269PLUS-D/O-216-100P-HI be used with a 120V or 240V control supply?
A: No. The control power supply is factory-configured for 216V AC. Using a different voltage will damage the relay. Ensure your control transformer secondary matches 216V AC before installation.
Q: Is this relay compatible with the GE 469 Motor Management Relay?
A: The 269 Plus and 469 are separate product families. The 469 offers additional features (differential protection, power metering). The 269 Plus is a direct replacement within the 269 Plus family only. Cross-family replacement requires engineering review.
Q: Does this unit include Modbus RTU communication as standard?
A: RS-485 Modbus RTU is available as an option on the 269 Plus platform. Confirm the specific unit’s communication option code when ordering if SCADA integration is required.
Q: What is the CT ratio flexibility — can I use a 50:5A CT with this relay?
A: The 100P designation indicates the relay is configured for 100:5A CTs. The 269 Plus platform supports multiple CT ratio settings via programming. Consult the GE Multilin 269 Plus Instruction Manual (GEK-106288) for CT ratio programming ranges and accuracy implications.
Q: What is the lead time for this part?
A: Typical lead time is 1–5 business days for in-stock units. Contact us for real-time availability confirmation.
