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 interrupting short-circuit currents quickly while allowing overload currents to pass without nuisance tripping.
Is this fuse suitable for 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 striker indication system provides a visual or mechanical indication when the fuse has blown, enabling quick identification of the faulted fuse without disassembly.
Can this fuse be used in UL-certified equipment?
Yes, this fuse meets UL standards with a rated voltage of 700 V AC, making it suitable for UL-certified equipment.
