Frequently Asked Questions
What does the aR characteristic mean?
The aR characteristic indicates that the fuse is a partial-range high-speed fuse designed to protect semiconductor devices by interrupting short-circuit currents quickly while allowing normal operational currents.
Can this fuse be used in DC applications?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
How does the double indicator system work?
The double indicator provides two visual signals to clearly show whether the fuse has blown, improving safety and maintenance efficiency.
Is this fuse compatible with standard NH3 fuse holders?
Yes, it is designed for NH size 3 fuse holders with clip mounting for easy installation and replacement.
