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-circuits rapidly while allowing low overload currents to pass without blowing, ensuring sensitive devices are protected effectively.
Can this fuse be used in DC applications?
This fuse is rated for AC applications only, as indicated in the technical specifications. For DC applications, a fuse specifically rated for DC voltage should be used.
How does the integral striker indication system work?
The integral striker is a mechanical indicator that triggers when the fuse element melts, providing a visible or remote signal that the fuse has operated and needs replacement.
Is this fuse RoHS compliant?
Yes, the product is RoHS compliant, ensuring it meets environmental standards restricting hazardous substances.
