The 690/700V 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 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. Features: Multiple body sizes and terminals or blades combination; aR Class according to IEC 60269-4 and VDE 636-23; Very low I²t for improved semiconductor protection; Ultra fast acting; Current limiting; Superior cycling capability - Certifications: IEC 60269-4 Compliance; UL/CSA Recognized E76491; CCC 1359.4
