Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic indicates the fuse is designed to protect power semiconductors by interrupting short-circuit currents quickly while allowing normal operational currents without nuisance tripping.
Can this fuse be used in DC circuits?
This fuse is rated for AC applications only, as specified in the technical specifications. For DC applications, a fuse specifically rated for DC should be used.
How does the striker indication system work?
The striker mechanism provides a mechanical indication by ejecting a visible striker when the fuse operates, allowing quick identification of a blown fuse without disassembly.
What mounting options are available for this fuse?
This fuse is designed for bolted mounting, ensuring a secure and stable installation in fuse holders or panels compatible with DIN 110 blade connections.
