Product Short Description
The 469-P5-HI-A20-E-H is a member of the GE Multilin 469 series of motor-protection and management relays. Designed for medium- to large-horsepower AC motors, it combines advanced protection algorithms, metering, and control logic in a single, drawer-style package. The unit is suited for continuous-duty, critical-process motors found in heavy industry, infrastructure, and energy facilities.
