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 interrupting overcurrents quickly while allowing for short-term overloads typical in such applications.
Can this fuse be used in DC circuits?
No, this fuse is specified for AC applications only, as indicated in the technical specifications.
How does the striker indication system work?
The striker is a mechanical indicator that triggers when the fuse blows, providing a visible or remote signal to facilitate quick identification and replacement.
Is the fuse RoHS compliant?
Yes, the fuse complies with RoHS standards, ensuring it is free from hazardous substances.
