GE 369-HI-R-M-0-0-0-H-E Multilin 369 Motor Management Relay

GE 369-HI-R-M-0-0-0-H-E belongs to GE Multilin 369 series digital motor management relay, designed for medium-size three-phase AC motors. It integrates comprehensive motor protection, metering, control and waveform capture functions to protect motors from overload, locked rotor, phase unbalance and ground fault risks.

This relay supports up to 12 RTD temperature inputs for winding and bearing temperature monitoring, equipped with local LCD display and keypad for parameter setup. It has multiple communication options and harsh environment coating, widely used in power plant, petrochemical and water treatment MCC cabinet spare replacement and motor protection retrofit projects.
