Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed to protect semiconductor devices by clearing short-circuits rapidly while allowing inrush currents typical in motor and power electronics applications.
Can this fuse be used in 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 is a mechanical indicator that pops out when the fuse blows, providing a clear visual indication that the fuse needs replacement.
Is this fuse RoHS compliant?
Yes, the fuse is RoHS compliant, ensuring it meets environmental and safety standards.
