Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) characteristic means the fuse is designed to protect semiconductor devices by clearing short-circuits quickly, but it allows certain overloads to pass without blowing, preventing nuisance trips.
Can this fuse be used in DC applications?
No, this specific fuse is rated for AC applications only, as indicated by the AC rating in the technical specifications.
How does the striker indication system work?
The striker mechanism provides a visual indication when the fuse has operated by releasing a mechanical indicator, allowing quick identification of blown fuses without disassembly.
What mounting options are available for this fuse?
This fuse uses bolted mounting with open slot blades, ensuring secure and reliable installation in compatible fuse holders or panels.
