Protistor ®
Semiconductor (AC) fuses

Protistor ® Square-body Fuses: NH Plain Blades gS
NH Solid Blades 690 VAC sizes 000 to 3

®
gS-class Protistor NH 690 VAC fuse-links provide
maximum fl exibility 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 fl exibility in equipment
design.
They have pure silver fuse elements embedded in
2
bound sand which provides optimized I 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 fi rst gS-class range
the fuse in service. in the marketplace!
