Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic means the fuse is designed to protect semiconductor devices by clearing short-circuits rapidly while allowing for some overload current without nuisance blowing.
Can this fuse be used in DC applications?
This fuse is rated for AC applications only, as specified in the technical specifications.
How does the striker indication system work?
The integrated striker provides a mechanical indication by popping out when the fuse blows, allowing for quick visual identification of a fault.
What fuse holders are compatible with this fuse?
This fuse fits size 70 clip-mounted fuse holders with plain blade terminals designed for high-speed semiconductor protection fuses.
