1 Protistor size 31 ar SEMICONDUCTOR PROTECTION FUSES SQUARE BODY HIGH-SPEED FUSE-LINKS AC PROTECTION FEATURES & BENEFITS Multiple body sizes and terminals or blades combination ar Class according to IEC and VDE Very low I²t for improved semiconductor protection Ultra fast acting Current limiting Superior cycling capability APPLICATIONS The 69/7V 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. They have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors and IGBT devices. They 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. Each fuse-link can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.
