Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic indicates that the fuse is designed for high-speed protection of semiconductor devices, interrupting short-circuit currents quickly but allowing certain overloads to pass without blowing.
Is this fuse suitable for DC applications?
No, this specific fuse is rated for AC applications only, as indicated in the technical specifications.
How does the striker indication system work?
The striker is a mechanical indicator that activates when the fuse blows, providing a clear visual signal that the fuse needs replacing.
Can this fuse be used in motor drives?
Yes, this fuse is commonly used in motor drives and other power electronics equipment requiring fast and reliable semiconductor protection.
