Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed to protect power semiconductors by providing high-speed interruption of short-circuits, but it does not protect against overloads.
Is this fuse suitable for 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 integrated striker mechanism provides a visual indication by releasing a striker when the fuse blows, allowing quick identification of a fault without disassembly.
Can this fuse be used in both IEC and UL rated equipment?
Yes, this fuse is rated for 690VAC under IEC standards and 700VAC under UL standards, making it suitable for equipment complying with either certification.
