Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) speed characteristic indicates that the fuse is designed for high-speed protection of semiconductor devices, clearing faults rapidly to prevent damage, but it does not provide full-range protection for all overload conditions.
Can this fuse be used in DC circuits?
No, this fuse is rated for AC applications only, as specified under the 'AC or DC' technical specification.
What is the purpose of the striker indication system?
The striker provides a mechanical indication when the fuse has blown, enabling remote signalling or easy visual confirmation of fuse status.
Is the fuse suitable for use in renewable energy systems?
Yes, it is suitable for protecting power electronics in renewable energy applications such as solar inverters and wind turbine converters, provided the voltage and current ratings are respected.
