Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic indicates that this fuse is designed to protect semiconductor devices by clearing short-circuits rapidly while allowing for certain inrush currents, providing selective and reliable protection.
Can this fuse be used in DC applications?
No, this fuse is rated for AC applications only, as specified by its AC voltage ratings and characteristics.
How does the striker indication system work?
The striker indication system provides a mechanical signal when the fuse has operated, allowing for quick visual or remote confirmation that the fuse has blown and needs replacement.
Is this fuse suitable for panel mounting?
Yes, the fuse features open slot blades and bolted mounting suitable for panel or fuse holder installation designed for size 71 fuses.
