Square-body Fuses
PSC gR sizes 7x - 690 VAC
Main characteristics
Ferraz Shawmut PSC-gRB 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, full range fuses engineered
to provide state of the art protection for power semicon-
ductors 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.
