Mersen Protistor® size 73 aR, 600 to 1250VAC (IEC) / 1300VAC (UL) L301057

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. 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 Applications Protection of inverters, motor drives, UPS systems and similar 690V or less equipments.
