Description
GE 469-P1-HI-A20-E-H High Performance Relay SR Protector
The GE Multilin 469-P1-HI-A20-E-H is a high-performance motor management relay engineered to safeguard and optimize medium to large industrial motor systems. As a cornerstone of GE’s Multilin 469 series, this relay integrates advanced protection, diagnostics, and control capabilities to ensure reliable motor operation in demanding environments such as oil & gas production, mining, water treatment, and manufacturing. By monitoring critical parameters like current, voltage, and temperature, the 469-P1-HI-A20-E-H acts as a vital guardian, preventing overloads, phase imbalances, and other motor-threatening conditions while providing real-time data for predictive maintenance.

The 469-P1-HI-A20-E-H distinguishes itself through its high-speed processing and adaptive protection algorithms. Its 1A phase CT secondary compatibility ensures precise current measurement, while the configurable overload curves and single CT differential protection adapt to diverse motor types and load profiles. Unlike basic relays, this unit offers self-diagnostic capabilities, including rotor health assessment and event logging, which reduce downtime by identifying issues before they escalate.
