Frequently Asked Questions
What does the 'aR' speed characteristic mean?
The 'aR' characteristic indicates a high-speed fuse designed to protect semiconductor devices by clearing short circuits rapidly while allowing normal overload currents to pass without nuisance tripping.
Is this fuse suitable for DC applications?
No, this fuse is specified for AC applications only, as indicated in the technical specifications.
How does the striker indication system work?
The striker provides a mechanical indication by popping out when the fuse blows, allowing for quick visual inspection and enabling remote signalling systems to detect fuse status.
Can this fuse be used in UL and IEC standard systems?
Yes, it is rated for 700V UL and 690V IEC systems, making it compliant with both standards.
