Ferraz Shawmut - Mersen F322051 High-Speed Fuse NH 0

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; gS Class according to IEC 60269-4; Low I²t for improved semiconductor protection; Fast acting; Highly current limiting; Excellent cycling capability; Reduced power dissipation; No derating in standard NH fusegear; High widstanding against inrush current and overloads - Certifications: IEC 60269-4 Compliance; UL/CSA Recognized Component; CCC GB 1359.4
