The 690/700V Protistor fuse-links provide maximum flexibility in equipment design and ultimate protection for small power conversion equipment. The Protistor have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors, GTO s and IGBT devices. Fuses are assembled with pure silver, die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I,t and high interrupting rating level. All contact surfaces are silver plated and all hardware is non-magnetic. Each fuse-link can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.
