Frequently Asked Questions
What does the 'aR' speed characteristic mean?
The 'aR' rating indicates a high-speed fuse designed specifically for semiconductor protection, capable of interrupting short-circuit currents quickly to protect sensitive devices.
Is this fuse suitable for DC applications?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
How does the striker indication system work?
The integrated striker provides a visual indication when the fuse has operated (blown), allowing for quick identification and replacement.
Can this fuse be used in systems with voltages exceeding 700V?
This fuse is rated for up to 700V UL and 690V IEC AC systems. Using it beyond these ratings is not recommended for safety and performance reasons.
