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 semiconductors by clearing short-circuit faults rapidly, but it does not provide full-range protection against overloads.
Can this fuse be used in DC circuits?
No, this fuse is specified for AC applications only, as indicated in the technical specifications.
How does the striker indication system work?
The striker system provides a mechanical indication of fuse operation by triggering a visible signal or enabling remote signalling when the fuse blows.
Is this fuse RoHS compliant?
Yes, the product is RoHS compliant, ensuring it meets environmental and safety standards.
