Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) speed characteristic indicates that the fuse is designed to protect semiconductor devices by clearing short-circuits rapidly, while allowing normal operational overloads within a certain range.
Can this fuse be used in DC applications?
No, this fuse is specified for AC applications only, as indicated in the technical specifications.
What is the function of the striker indication system?
The striker indication system provides a mechanical signal when the fuse has blown, enabling remote fault detection and easier maintenance.
Is this fuse RoHS compliant?
Yes, the fuse complies with RoHS directives, ensuring it is free from hazardous substances.
