Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed to protect semiconductor devices by providing fast interruption of overloads and short circuits, but it does not provide protection against overload currents below a certain threshold.
Can this fuse be used in DC circuits?
No, this fuse is rated for AC applications only, as indicated in the technical specifications.
How does the striker indication system work?
The striker mechanism activates upon fuse operation, providing a visual or remote indication that the fuse has blown, which enhances safety and simplifies maintenance.
Is this fuse RoHS compliant?
Yes, the product is RoHS compliant, ensuring it meets environmental and safety standards.
