Frequently Asked Questions
What does the "aR" characteristic mean for this fuse?
The "aR" characteristic indicates that this fuse is a partial-range semiconductor fuse designed to protect power semiconductors by clearing short-circuits rapidly while allowing normal inrush currents without nuisance tripping.
Is this fuse suitable for DC applications?
No, this particular fuse is rated for AC applications only, as specified in the technical specifications.
How does the striker indication system work?
The striker indication system provides a mechanical indication of fuse operation by triggering a visible or tactile signal when the fuse element has blown, facilitating quick identification of a faulted fuse.
Can this fuse be used in systems above 700V AC?
No, this fuse is rated for a maximum AC voltage of 700V UL and 690V IEC. Using it above these voltages may compromise safety and performance.
