The GE 369 – HI – R – M – 0 – 0 – 0 – E is a motor management relay as part of General Electric Multilin’s 369 series. Engineered for medium – sized AC motors, it offers comprehensive protection and control features.

This relay is designed to safeguard motors and their associated components. It comes equipped with a metering function that monitors crucial electrical parameters such as voltage, watts, frequency, and energy. Based on the data collected, it can generate protective functions to prevent motor damage from abnormal electrical conditions. For example, if the voltage deviates from the normal range, the relay can take appropriate actions like tripping the circuit or sending out an alarm.

The event recording feature is another key aspect. Right after a trip occurs, the 369 – HI – R – M – 0 – 0 – 0 – E can report the cause of the trip, along with the temperature and data values at that moment. This information is invaluable for users to analyze system malfunctions, facilitating quicker troubleshooting and maintenance.

Pre – trip alarms are also a significant advantage. When a trip is impending due to issues such as ground faults, mechanical jams, or RTD (Resistance Temperature Detector) over – temperature, the relay can notify users in advance. This allows for preventive measures to be taken, minimizing unplanned downtime.

The relay also provides a motor health report. By leveraging the learned information and historical data of system trips, it can identify potential maintenance requirements, both in terms of when and where maintenance might be needed. This predictive maintenance functionality helps in optimizing motor performance and extending its lifespan.

In addition, it has an oscillography feature. Three waveform records are triggered during a trip, capturing sixteen data cycles. During this process, phase and ground currents, as well as contact input status, are captured. This data can be used for in – depth analysis of motor behavior during abnormal events.
