SEMICONDUCTOR PROTECTION FUSES
NH SQUARE BODY HIGH-SPEED FUSE-LINKS AC PROTECTION
FEATURES & BENEFITS
• 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
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.

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.
