Mersen Protistor® size 000/00 aR, 500 to 690VAC (IEC) / 700VAC (UL) A330027

The 690/700V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for small power conversion equipment. These ultra-fast acting aR fuses 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. Features aR Class according to IEC 60269-4 and VDE 636-23 Very low I²t for improved semiconductor protection Ultra fast acting Superior cycling capability Applications Protection of inverters, motor drives, UPS systems and similar 690V or less equipments.
