Frequently Asked Questions
What does the aR speed/characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed to protect semiconductors by clearing short-circuits quickly but allows for certain overloads without blowing, making it suitable for semiconductor protection.
Can this fuse be used in DC applications?
This particular fuse is rated for AC applications only as specified in the technical specifications.
How does the striker indication system work?
The striker indication system provides a mechanical signal by ejecting a striker when the fuse blows, allowing for easy visual or remote indication of fuse status.
Is this fuse suitable for panel mounting?
Yes, the fuse is designed for bolted mounting, making it suitable for panel builders and OEMs.
