Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) speed characteristic means the fuse is designed to protect semiconductor devices by interrupting fault currents quickly while allowing short-duration overloads that are typical in power electronics.
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 uses a mechanical indicator that pops out when the fuse operates, providing a clear visual signal that the fuse has blown and needs replacement.
Can this fuse be used in non-metric thread holders?
This fuse is designed with metric threads for installation; using it in non-metric holders is not recommended and may affect performance and safety.
