GE 469-P5-HI-A20-T-H Motor Management Relay with Coating

Product Description

Comprehensive Protection for High-Inertia Motors

The GE Multilin 469-P5-HI-A20-T-H is a sophisticated microprocessor-based relay designed for the protection, management, and monitoring of medium to large horsepower motors. This specific configuration of the 469 series provides a robust thermal model that accounts for motor heating due to negative sequence currents, cyclic loading, and ambient temperature. By integrating voltage-dependent overload curves and torque metering, the 469-P5-HI-A20-T-H ensures that high-inertia starts are managed safely, preventing premature insulation failure while maximizing motor service life in demanding industrial sectors like oil & gas, mining, and water treatment.

Advanced Asset Monitoring and Diagnostics

Beyond basic electrical protection, the 469-P5-HI-A20-T-H offers specialized mechanical protection features, including broken rotor bar detection and bearing vibration monitoring via analog inputs. The unit’s "HI" control power range (90–300 VDC or 70–265 VAC) ensures operational stability across varying grid qualities. With its integrated oscillography and event recording capabilities, maintenance teams can perform detailed root-cause analysis of trips, significantly reducing troubleshooting time. The 469-P5-HI-A20-T-H also features a "T" suffix indicating optional conformal coating, providing superior protection against humidity and chemically corrosive atmospheres common in chemical processing plants.
