SEMICONDUCTOR PROTECTION FUSES
Ferraz Shawmut 1250/1300V PSC fuse-links provide maximum
flexibility in equipment design and ultimate protection for today’s
power conversion equipment. These square body fuse-links are
available in four different body sizes, each size having four world-
wide acceptable mounting styles. The different mounting styles
and body sizes along with a broad range of ampere ratings allow
greatest flexibility in equipment design.
The Ferraz Shawmut PSC fuses have been engineered to provide
state-of-the-art protection for SCR’s, diodes, thyristors, GTO’s
and IGBT devices. They have pure silver die-cut elements
embedded in solidified sand which helps control arcing charac-
teristics for low I
2
t and high interrupting rating. All contact
surfaces are silver plated and all hardware is non-magnetic.
All fuse links are equipped with a low voltage trip-indicator. This
trip-indicator can operate a field mountable microswitch which is
easily mounted directly onto the fuse even while in service.
