Item Long Description These 1250/1300V Protistor fuse-links provide maximum flexibility in equipment design and ultimate protection for today's power conversion equipment. These aR ultra-fast acting square body fuse-links are available in different body sizes, each size having multiple worldwide acceptable mounting styles.The Protistor have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors and IGBT devices. Fuses are assembled with die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower It and high interrupting rating level. All contact surfaces are silver plated and all hardware is non-magnetic.All fuse-links can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.
