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 interrupting short-circuit currents rapidly, but it allows for certain overload currents without blowing, ensuring selective protection.
Is this fuse suitable for DC applications?
No, this fuse is specified for AC applications only, as indicated by the 'AC or DC' specification stating AC.
How does the striker indication system work?
The striker indication system provides a visible and mechanical indication when the fuse has blown, allowing for quick identification and replacement.
Can this fuse be used in renewable energy systems?
Yes, it is suitable for use in renewable energy applications such as solar and wind power systems where high-speed semiconductor protection is required.
