Semiconductor square body NH fuse, class aR
500 - 700 VAC, 16 - 1000 A | Protistor®
Mersen
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.
Applications :
Protection of inverters, UPS
systems, motor drives and similar
700V or less equipment.
