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

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.
