Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial-range) characteristic means the fuse is designed to protect power semiconductor devices by providing fast interruption of short-circuit currents while allowing for temporary overloads without nuisance blowing.
Can this fuse be used in DC circuits?
This fuse is specified for AC applications only, as indicated by the technical specifications. For DC circuits, a fuse rated specifically for DC use should be selected.
What is the purpose of the striker indication system?
The striker indication system provides a mechanical indication that the fuse has blown, allowing for quick visual inspection without removing the fuse from its holder.
Is this fuse reusable after it has operated?
No, this is a one-time-use fuse. Once it has operated (blown), it must be replaced to restore circuit protection.
