Frequently Asked Questions
What does the 'aR' characteristic mean for this fuse?
The 'aR' characteristic indicates that the fuse is a partial-range semiconductor fuse designed to protect power semiconductors by providing fast interruption of overloads and short circuits while allowing normal inrush currents.
Can this fuse be used in DC applications?
This fuse is rated for AC applications only, as indicated by its specifications. For DC protection, a fuse specifically rated for DC should be selected.
How does the striker indication system work?
The striker is a mechanical indicator that activates when the fuse blows, providing a clear visual signal that the fuse needs replacement, facilitating quick maintenance.
Is this fuse compatible with all Size 72 fuse holders?
It is compatible with fuse holders designed for Size 72 fuses with DIN 110 blade terminals, but always verify compatibility with the specific fuse holder manufacturer’s recommendations.
