Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) characteristic means the fuse is designed to protect semiconductor devices by quickly interrupting short-circuit faults while allowing for inrush currents typical in power electronics.
Can this fuse be used in DC circuits?
No, this particular fuse is rated for AC applications only, as indicated by its AC voltage ratings and specifications.
How does the striker indicator work?
The striker indicator provides a visual signal by ejecting a striker when the fuse element melts, allowing for quick identification of a blown fuse without disassembly.
What is the significance of metric threaded flush ends?
Metric threaded flush ends ensure secure mechanical and electrical connection in panels designed for metric fasteners, improving installation reliability and safety.
