Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial range) characteristic indicates the fuse is designed to protect semiconductor devices by quickly interrupting short-circuit faults while allowing for normal inrush currents, providing selective and reliable protection.
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 striker indication system work?
The integrated striker mechanism physically moves or triggers an indicator when the fuse blows, providing a clear visual signal that the fuse has operated and requires replacement.
What mounting options are available for this fuse?
This fuse is designed for bolted mounting with flush ends and metric threads, ensuring a secure and stable installation.
