NH 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
in drives.
These solid blades 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
bound sand which provides optimized I
2
t and high
breaking capacity.
All contact surfaces are silver plated and all hardware
non-magnetic.
These products comply with the RoHS European
Directive.
All fuses are standard with a low voltage dual
blown fuse indicator. This indicator can operate a
microswitch which is easily mounted directly on to
the fuse in service.

Microswitches
MSNHB6 + PRES: consult us (6,3mm clips)
MSNHB2 + PRES: consult us (2.8 mm clips)
Automatically resetable, these microswitch systems indicate fuse presence (PRES) and proper
mounting
In case of improper mounting or fuse melting, this is indicated (terminal 1-4 closed)
