Frequently Asked Questions
What does the 'aR' speed characteristic mean?
The 'aR' rating indicates that the fuse is a high-speed semiconductor fuse designed to protect semiconductor devices by interrupting fault currents rapidly, minimising damage.
Is this fuse suitable for DC applications?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
How does the striker indication system work?
The striker mechanism provides a mechanical indication of fuse operation by physically ejecting or moving when the fuse blows, enabling quick visual fault detection.
Can this fuse be used in motor drive protection?
Yes, it is suitable for protecting semiconductor components in motor drives and inverters due to its high-speed and high breaking capacity.
