GE Multilin 369-HI-R-B-F-P-0-E

The 369-HI-R-B-F-P-0-E is a Multilin 369 motor management protection relay from GE Vernova, dedicated for medium and low voltage AC motor protection, control and condition monitoring. This 369-HI-R-B-F-P-0-E adopts FlexCurve thermal overload protection algorithm, integrating locked rotor, current unbalance, single-phase loss, earth fault, undervoltage, underpower and phase reversal protection. The R option supports 12 channels of RTD input for stator winding and bearing temperature monitoring. The suffix string HI-R-B-F-P-0-E defines auxiliary supply range, RTD function, I/O configuration, metering package, Profibus communication, special test and certification options for this specific variant.

This 369-HI-R-B-F-P-0-E is equipped with local LCD and keypad for on-site parameter setting, measured value display, fault review and manual breaker control. It provides disturbance waveform capture, sequence of event records and motor health diagnostic reports. It supports Modbus RTU and Profibus DP communication to connect with PLC, DCS and SCADA systems, and it can be configured via EnerVista software. It has programmable binary inputs and relay outputs for motor interlock, trip, alarm and auxiliary control signals. It also supports VFD-fed motor and two-speed motor application scenarios.

The 369-HI-R-B-F-P-0-E is widely used for fans, pumps, compressors and conveyor motors in power plants, mining, oil & gas and chemical facilities. The Multilin 369 series has been discontinued by GE Vernova, the successor model is Multilin 859. Most available 369-HI-R-B-F-P-0-E units are tested surplus spare parts for motor protection cabinet overhaul and emergency replacement.
