Frequently Asked Questions
What does the 'aR' characteristic mean for this fuse?
The 'aR' characteristic indicates a high-speed semiconductor fuse designed to protect power semiconductors by interrupting short-circuit currents rapidly while allowing normal operational currents to pass without nuisance tripping.
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 striker indication system provides a mechanical indication when the fuse has operated (blown), allowing quick visual identification of the faulted fuse without disassembly.
Can this fuse be used in systems exceeding 1300V?
No, the maximum rated voltage for this fuse is 1300VAC (UL) and 1250VAC (IEC). Using it above these ratings may compromise safety and performance.
