Semiconductor protection square body fuse, class aR
750 VDC; 50 - 160 A; size 1
Mersen
ultimate protection for small power conversion equipment.
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
690V or less equipment.
