The Mersen Protistor® size 73 aR semiconductor protection fuses are ultra-fast acting square body fuse-links designed for the ultimate protection of power conversion equipment. Engineered specifically to safeguard semiconductors such as diodes, thyristors, and IGBT devices, these fuses utilize die-cut elements embedded in solidified sand to control arcing characteristics, providing exceptionally low I²t and high interrupting ratings. The A090UD73TTI1400 model features silver-plated contact surfaces for superior conductivity and includes TTI 1/2in-13 unified coarse threaded terminals for secure integration into industrial power systems.
