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 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
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
Applications
Protection of inverters, motor drives, UPS systems and similar 700V or less equipments.
