Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed for semiconductor protection, providing high-speed interruption for overloads and short circuits, but not for protection against overload currents in the entire range.
Can this fuse be used for DC applications?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
What is the purpose of the double indicator?
The double indicator provides a clear visual signal when the fuse has blown, allowing for quick identification and replacement.
Is this fuse compliant with international standards?
Yes, it complies with IEC and UL standards for rated voltage and breaking capacity, ensuring safety and reliability.
