1 Semiconductor () fuses PS ar sizes 9x V Main characteristics Ferraz Shawmut 500 V PS fuse-links provide maximum flexibility in equipment design and ultimate protection for today s power conversion equipment. These square body fuse-links are available in three different body sizes, each size having four worldwide acceptable mounting styles. The different mounting styles and body sizes along with a broad range of ampere ratings allow greatest flexibility in equipment design. The Ferraz Shawmut PS fuses have been engineered to provide state-of-the-art protection for SR s, diodes, thyristors, GTO s and IGT devices. They have pure silver die-cut elements embedded in solidified sand which helps control arcing characteristics for low I 2 t and high breaking capacity. ll contact surfaces are silver plated and all hardware is non-magnetic. ll fuse links are equipped with a low voltage trip-indicator. This trip-indicator can operate a field mountable microswitch which is easily mounted directly on to the fuse even while in service.
