630A 690V NH3 SEMI

NH3GS69V630PV  6,9GS3PV0630  Very Fast Acting Semiconductor Fuse

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.

  • 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


  • Protection of inverters, motor drives, UPS systems and similar 700V or less equipment.
