Ferraz Shawmut - Mersen H320489 High-Speed Fuse NH 2

The 690/700V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for today's power conversion equipment. These NH style fuse-links are defined as per DIN 43620/00 for a worldwide acceptance into NH modular system fuse-holders, fuse switch disconnectors for direct installation.The Protistor® have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors, GTO's and IGBT devices. Fuses are assembled with pure silver, 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; aR Class according to VDE 636-23 and IEC 60269-4; Very low I²t for improved semiconductor protection; Ultra fast acting; Current limiting; Superior cycling capability; Indication system with double indicator - Certifications: UL/CSA Recognized Component; IEC 60269-4 Compliance
