Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic indicates that the fuse is designed to protect semiconductor devices by clearing short-circuit faults quickly while allowing for normal inrush currents, providing selective and reliable protection.
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 is a mechanical indicator that visibly pops out when the fuse has operated (blown), providing a clear visual status indication to facilitate quick maintenance.
Can this fuse be used in any fuse holder?
This fuse requires a bolted mounting fuse holder compatible with Size 71 fuses and open slot blade terminals to ensure proper installation and performance.
