Mersen A110UD73TTI1000 K301056 1000A aR Fuses (3 Pieces)

Mersen Protistor® Semiconductor Fuse A110UD73TTI1000

The Mersen A110UD73TTI1000 is an ultra-rapid (aR Class) Protistor® square-body fuse, designed to deliver optimal protection for power semiconductors, including diodes, thyristors, and IGBTs. With its very low I²t (Joule integral) and a high interrupting rating, it is ideally suited for safeguarding sensitive components in critical applications like variable speed drives, power rectifiers/inverters, UPS systems, and DC drives. This model is equipped with a visual Type T trip indicator for immediate indication of fuse status.
