Frequently Asked Questions
What does the 'aR' characteristic mean for this fuse?
The 'aR' characteristic indicates that the fuse is a partial-range high-speed fuse designed to protect semiconductor devices by interrupting short-circuit currents rapidly while allowing overload currents to pass for a short time.
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 indication system provides a mechanical signal when the fuse has operated, allowing quick visual identification of blown fuses without dismantling equipment.
Is this fuse compliant with international standards?
Yes, it meets IEC standards for 900VAC and UL standards for 1000VAC, ensuring global compliance and reliability.
