Frequently Asked Questions

What does the aR characteristic mean?

The aR (partial range) characteristic indicates that the fuse is designed to protect semiconductor devices by quickly interrupting short-circuit currents while allowing normal operational overloads to pass without blowing.

Can this fuse be used in DC applications?

No, this fuse is rated for AC applications only, as specified in the technical specifications.

What is the purpose of the striker indication system?

The striker indication system provides a mechanical indication when the fuse has operated, allowing for quick visual identification of a blown fuse without disassembly.

Is this fuse RoHS compliant?

Yes, the fuse complies with RoHS regulations, ensuring it is free from hazardous substances.
