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 I2t 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.
