Semiconductor (AC) fuses
Protistor® Square-body Fuses: NH Plain Blades gS
1
Protistor®
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
bound sand which provides optimized I2t 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.
Features/Benefi ts
Broad range of ampere ratings in each body size for design fl exibility IEC 60269-4 compliance for
fuses for worldwide semiconductor applications
