Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial-range) characteristic indicates the fuse is designed to protect semiconductor devices by clearing short-circuit faults rapidly while allowing for certain overload conditions without blowing.
Can this fuse be used in DC applications?
No, this fuse is rated specifically for AC applications up to 1250V and is not suitable for DC circuits.
What is the purpose of the striker indication system?
The striker indication system provides a visual signal when the fuse has operated, allowing quick identification of blown fuses without disassembly.
How is the fuse mounted?
This fuse uses bolted mounting with flush ends and metric threads for a secure and reliable connection.
