Description
The NMB-MAT 06025SS-24N-AL is a precision-engineered DC axial cooling fan designed specifically for the rigorous thermal demands of industrial automation equipment. Manufactured by MinebeaMitsumi, this 60mm unit serves as a critical OEM component for thermal management within Schneider Electric inverters and Yaskawa servo driver systems. The fan features a compact 60mm x 60mm x 25mm form factor, optimized to deliver high static pressure, which is essential for forcing air through the dense heatsink fins of Variable Frequency Drives (VFDs) and power electronics. Operating at a nominal 24V DC, this model utilizes a three-wire configuration that integrates a sensor signal (typically a Locked Rotor Alarm or Tachometer), allowing the host drive to monitor fan health in real-time and prevent catastrophic overheating of IGBT modules. Built with NMB’s proprietary bearing technology, it ensures extended service life under continuous duty cycles. Adhering to Original Engineering specifications, this component guarantees exact physical fitment and electrical matching, eliminating the risks associated with generic aftermarket replacements.
