HIGHLIGHTS:
PSC
1250/1300 Volt 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
2t 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.
Choice of mounting styles gives wide choice for
equipment design
Broad range of ampere ratings in a given body
size for design flexibility
IEC 269-4 compliance for fuses for worldwide
semiconductor applications
