Mersen A130UD73TTI900 J301055 900A Fuses (3 Pieces)

Mersen Protistor® Semiconductor Fuse A130UD73TTI900

The Mersen A130UD73TTI900 is an ultra-rapid (aR Class) Protistor® fuse designed to protect power semiconductors, including diodes, thyristors, and IGBTs. This square body fuse features very low I²t (Joule integral) and a high interrupting rating, making it suitable for protecting sensitive components in applications such as variable speed drives, rectifiers, inverters, DC drives, and UPS systems. It includes a visual Type T trip indicator for easy fuse status monitoring.
