Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed for high-speed interruption of semiconductor circuits, protecting against short circuits while allowing normal operational currents.
Is this fuse suitable for DC applications?
No, 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 visual indication by releasing a striker when the fuse blows, making it easy to identify a faulted fuse without disassembly.
Can this fuse be used in outdoor environments?
While the fuse has a robust ceramic body, it should be installed within appropriate enclosures rated for outdoor use to protect against environmental factors.
