Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic means the fuse is designed to protect semiconductor devices by interrupting short-circuit faults quickly, but it does not provide overload protection.
Can this fuse be used in DC applications?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
What is the purpose of the striker indication system?
The striker indication system provides a mechanical signal when the fuse has blown, allowing remote indication of fuse status for easier maintenance and safety.
Is this fuse RoHS compliant?
Yes, the fuse complies with RoHS regulations, ensuring it is free from hazardous substances.
