Product Overview

The GE Multilin 469 is a comprehensive motor management relay designed to provide superior protection, monitoring, and diagnostics for medium-to-large-sized motors. The 469-P5-HI-A20-E model differs from the P1 variant primarily by utilizing 5 A phase current transformer secondaries, matching standard industrial CT outputs.

Key Features:

  • Advanced Protection: Includes comprehensive protection elements such as thermal overload, short circuit, phase reversal, and undercurrent protection.

  • Enhanced Monitoring: The “E” designation indicates an enhanced front panel interface, providing operators with clear, real-time data visibility and simplified navigation for settings and diagnostics.

  • Reliable Communication: Built-in Modbus RTU support allows for seamless integration into existing SCADA or DCS architectures for remote monitoring and control.

  • Industrial Robustness: Designed for harsh environments, these units feature reliable draw-out construction for ease of maintenance and replacement.

Installation & Commissioning Reminders

Cut off high voltage and auxiliary power before wiring. Strictly follow CT polarity requirements; wrong wiring will cause protection malfunction. Separate CT cables, power wires and communication cables to reduce electromagnetic interference.
Set motor rated parameters, protection curves, RTD alarm/trip thresholds via front panel or EnerVista software. Configure communication address, baud rate and analog output mapping according to upper system requirements.
Complete protection injection testing, verify overload, ground fault, temperature protection and trip logic. Confirm real-time data upload to DCS/SCADA works steadily.
After acceptance, implement periodic inspection: check terminal tightness, display status and clear accumulated dust to maintain reliable motor protection performance.
