This Integrated Protection and Control System is part of General Electric Multilin’s 369 series and is suitable for use with medium-sized AC motors. By using waveform capture, event reports, data logging, and built-in optional metering capabilities (included in this model), the 369-HI-R-M-0-0-0 is able to lower maintenance costs and reduce time spent troubleshooting. Data produced by the relay can be easily reviewed on the relay’s 40-character liquid crystal display or on a computer running General Electric’s EnerVista 369 software program. EnerVista can also trend this data for more effective analysis.
Protective system features of the 369-HI-R-M-0-0-0 like Short Circuit Trip are able to limit damage to motor components by detecting excess magnitude and generating an appropriate response. If the magnitude rises above the Phase CT Primary x Pickup Level for a specified amount of time, a trip will transpire. The amount of time can be adjusted in 10 ms increments and configured through the relay’s setpoint system. While accidental tripping can occur during motor start if the short circuit time delay is too sensitive, users can fine tune these settings using system-generated data to find a suitable compromise.
The 369-HI-R-M-0-0-0 has a height of approximately 11.5 inches, a width of 8.5 inches, and a depth of 5.5 inches. The installation cut-out for the relay can be slightly smaller (11”H, 7”W) since the relay diminishes in size towards the back, with the front panel being the largest section of the device. An enhanced faceplate option is also available and will be denoted by an “E” ending the model number on AX Control’s 369 series page.
Frequently Asked Questions about 369-HI-R-M-0-0-0
What does the R option afford the 369-HI-R-M-0-0-0 Multilin GE motor management relay?
The R option of the 369-HI-R-M-0-0-0 indicates that the 369 motor management relay has additional RTD inputs built in to the base unit. These additional 12 RTDs are type 3 wire with either 100 Ohm platinum, 100 Ohm nickel, 120 Ohm nickel, or 10 Ohm of copper composition. The RTD sensing current for the 369 R option is 3 mA. These RTD options range from either negative 40 degrees Celsius to 200 degrees Celsius or from negative 40 degrees C to positive 392 degrees C. The RTD inputs (option R) have an isolation that is 36 Vpk.
Is ventilation required for the GE Multilin digital relay 369-HI-R-M-0-0-0 to function for the protection and monitoring of three phase motors?
The 369-HI-R-M-0-0-0 is a relay within the 369 motor management relay Multilin GE series. This relay is designed to provide protection and monitoring of three phase motors as a motor management digital relay. There are no specific ventilation requirements listed by the manual with the direction to keep the ambient temperature within the specifications listed. In this case for a base unit the ambient temperature range is from -40 degrees C to positive 60 degrees C. Ventilation may be necessary for conditions within sunlight.
The metering capabilities included in this version of the part can be used in tandem with the relay’s setpoint system to generate increased and more specified protection for the system.
