Mersen A100UD73TTI1250 M301058 1250A aR Fuses (3 Pieces)

Mersen Protistor® Semiconductor Fuse A100UD73TTI1250

The Mersen A100UD73TTI1250 is an ultra-rapid (aR Class) Protistor® square body fuse, meticulously designed for the protection of power semiconductors, including diodes, thyristors, and IGBTs. This fuse is characterized by its exceptionally low I²t (Joule integral) value and a high interrupting rating, rendering it ideal for safeguarding sensitive components in critical applications such as variable speed drives, rectifiers, inverters, DC drives and UPS systems. It also features a visual Type T trip indicator to provide immediate indication of the fuse status.
