PSC - LR ranges

Ferraz Shawmut PSC-LR fuse-links provide maximum flexi-
bility in equipment design and ultimate protection for
today’s power conversion equipment. These square body
fuse-links are available in various body sizes with a broad
range of ampere ratings allowing the greatest flexibility in
equipment design.
25 URD 123 TTF 630 The Ferraz Shawmut PSC-LR fuse range has been engineered
to provide state of the art protection for high power
semiconductors such as diodes, thyristors, GTO’s, IGCT’s
and IGBT’s.
They have pure silver fuse elements embedded in solidified
sand which provides optimized I t and high interrupting

rating. All contact surfaces are plated and all hardware
4 URD TDF 1000 non-magnetic.
All fuses are standard with a low voltage blown fuse
9,5 URD 94 PPASF 3800
+ MC3E 1-5N indicator. This indicator can operate a microswitch which
is easily mounted directly onto the fuse in service.
