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 I²t 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.
Multiple body sizes and terminals or blades combination; Ultra fast acting; CCC GB 13539.4; Superior cycling capability; Current limiting; IEC 60269-4 Compliance; UL/CSA Recognized E76491; Very low I²t for improved semiconductor protection; aR Class according to IEC 60269-4 and VDE 636-23
