The PSC-LR Protistor® fuse-links is a high performance range designed to provide the best flexibility in equipment design and ultimate protection for today's 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 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.
