Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic means this fuse is designed to protect semiconductor devices by interrupting short-circuit currents quickly, but it does not provide protection against overload currents.
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 significance of the striker indication system?
The striker indication system provides a visible mechanical indication when the fuse has operated, allowing for quick 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.
