Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR characteristic indicates that the fuse is a partial-range semiconductor fuse designed to protect power semiconductors by interrupting high fault currents rapidly while allowing normal inrush currents to pass without nuisance tripping.
Can this fuse be used in 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 provides a visual and/or mechanical indication when the fuse has blown, allowing for quick and safe identification of a faulted fuse without disassembling the equipment.
What mounting options are available for this fuse?
This fuse is designed for bolted mounting, compatible with fuse holders and assemblies that accept Size 30 fuses with flush end terminals.
