Mersen A130UD73TTI400 B301048 400A aR Fuses (3 Pieces)

Mersen Protistor® Semiconductor Fuse A130UD73TTI400

The Mersen A130UD73TTI400 is an ultra-rapid (aR Class) Protistor® square-body fuse, meticulously designed to deliver high-performance protection for power semiconductors like diodes, thyristors, GTOs, and IGBTs. With its extremely low I²t (Joule integral) and a very high interrupting rating, it is ideal for safeguarding sensitive components in critical industrial applications such as variable speed drives, power rectifiers/inverters, UPS systems, and DC drives. This particular model is equipped with a visual Type T trip indicator for immediate identification of fuse status.
