Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed to protect power semiconductors by interrupting short circuits and overloads, but it does not provide full-range protection against all overcurrents.
Can this fuse be used in DC applications?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
What is the purpose of the integrated striker?
The integrated striker provides a mechanical indication of fuse operation that can be used for remote signalling, improving safety by alerting operators to fuse status without direct inspection.
Is this fuse compliant with international standards?
Yes, it complies with IEC and UL standards, ensuring reliable performance and acceptance in various international markets.
