Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) speed characteristic means the fuse is designed to protect semiconductor devices by rapidly interrupting short-circuit currents but allows for low overload currents without nuisance tripping.
Can this fuse be used in DC circuits?
No, this particular fuse is rated for AC applications only, as indicated in the technical specifications.
How does the striker indication system work?
The striker mechanism provides a visual indication by triggering a mechanical flag or striker when the fuse element blows, enabling quick identification of a faulted fuse.
Is this fuse RoHS compliant?
Yes, the product is RoHS compliant, ensuring it meets environmental and safety standards.
