FAQ

Q: What is NMTU-21C 3BSE017429R1?
A: It is a Thermal Resistance Power Module .

Q: Does "Thermal Resistance" on the NMTU-21C 3BSE017429R1 mean it can withstand high temperatures?
A: Not entirely. It refers more to the onboard circuitry's ability to process the inverter unit's thermal resistance sensing signal, ensuring the power module trips promptly when the safe thermal threshold is exceeded.

Q: After replacing this NMTU-21C 3BSE017429R1, does the inverter's temperature reading need calibration?
A: No. It's only a physical connection and signal forwarding layer; temperature compensation and calibration logic are stored in the firmware of the RMIO control board.

Q: Why does the inverter report a fault due to temperature rise even when the ambient temperature isn't high about NMTU-21C 3BSE017429R1?
A: This may be due to resistance drift in the thermistor detection circuit on the NMTU-21C baseboard. It's recommended to check the baseboard slots for increased contact resistance caused by oxidation.

Q: Will damage to the NMTU-21C 3BSE017429R1 cause the IGBT to burn out?
A: Extremely high risk. If the board's thermal protection monitoring fails, the power module may continue operating under overheating conditions, ultimately leading to IGBT thermal breakdown.
