369-HI-R-M-0-0-0-0 General Electric Multi Wire 369 Series

369-HI-R-M-0-0-0 is part of the General Electric multi wire 369 series motor management relay. This type of relay is designed to protect and control the motor and its supporting components. It has multiple built-in functions, including metering, event recording, pre trip alarms, and car health reports.
The metering function can monitor quantities such as voltage, wattage, frequency, and energy, and generate protection functions based on the generated value data. The event recording function can immediately report the cause of the trip, as well as the temperature and data values at the time of the trip, after the trip, allowing users to analyze problems that occur in the system. The pre trip alarm function can notify the user before tripping due to grounding faults, mechanical blockages, RTD overheating, and other reasons. The car health report function uses learned information and the history of system trips to identify when and where maintenance may be needed.
In addition, the protection system function of the 369-HI-R-M-0-0-0 type short-circuit trip can limit damage to motor components by detecting excessive values and generating appropriate responses. If the amplitude exceeds the CT main x-phase pickup level within the specified time, a trip will occur. The amount of time can be adjusted in increments of 10 ms and configured through the relay’s set point system. If the short circuit time delay is too sensitive, unexpected tripping may occur during motor startup. Users can use the system generated data to fine tune these settings to find a suitable compromise solution.
