GE 269PLUS-D/O-111-100P-HI Multilin 269Plus Motor Management Relay

GE 269PLUS-D/O-111-100P-HI is a drawout version of Multilin 269Plus microprocessor-based motor management relay. It delivers comprehensive protection, metering and control for three-phase industrial AC motors, monitoring current, temperature and operating status to prevent motor damage from overload, locked rotor and ground fault.

This relay supports RTD temperature monitoring, Modbus RS485 communication and configurable relay outputs. The drawout structure allows easy removal for maintenance without full cabinet shutdown. It is widely used in power plant, water treatment and petrochemical motor control cabinet spare replacement and retrofit projects.

FAQ

• 1. Q: What is GE 269PLUS-D/O-111-100P-HI?
      A: It is GE Multilin drawout type motor management relay, offering full protection, metering and communication for three-phase AC motors.

• 2. Q: What does D/O mean in the model code?
      A: D/O stands for Drawout, meaning the relay module can be pulled out without removing field wiring.

• 3. Q: Can it be hot swapped?
      A: Isolate motor primary circuit and control power before extraction; do not perform hot swap under live load condition.
