Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed for semiconductor protection, providing high-speed interruption of short-circuit currents while allowing for certain overload conditions.
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 system provides a mechanical indication by physically moving or ejecting when the fuse operates, allowing for easy visual identification of a blown fuse without disassembly.
Can this fuse be used in environments outside industrial settings?
While designed primarily for industrial power electronics, the fuse may be used in other settings requiring high-speed protection, provided the electrical and mechanical specifications are met.
