Semiconductor fuses
Ferraz Shawmut PSC-URD 690 VAC fuse-links provide
maximum flexibility in equipment design and ultimate protection
for today’s power conversion equipment. This range is a fast
acting, engineered to provide state of the art protection for
power semiconductors such as diodes, thyristors.
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.
They have pure silver fuse elements embedded in solidified
sand which provides optimized I
2
t and high breaking capacity.
All contact surfaces are plated and all hardware non-magnetic.
All fuses are standard with a low voltage blown fuse
indicator. This indicator can operate a microswitch which is
easily mounted directly on to the fuse in service.
Features/Benefits
Broad range of ampere ratings
in each body size for design flexibility
