Core Product Advantages and Features
gS semiconductor fusing characteristics
It adopts the gS fusing rating, which is optimized for short-circuit protection of semiconductor components. It has a fast response speed and can effectively reduce the impact of fault current on rectifier and inverter components.
Dual voltage rated design
With an AC rated voltage of 690V and a DC rated voltage of 250V, it can simultaneously meet the protection needs of industrial AC circuits and DC power electronic systems.
Pre-fuse indicator
The fuse is equipped with a status indicator on the front, which can be visually confirmed after the fuse blows, shortening the time for maintenance, troubleshooting and replacement, and reducing downtime losses.
Blade-type contact design
It adopts NH000 specification knife-type contact terminals, which are compatible with standard NH fuse holders, making installation and replacement easy.
