Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial-range) characteristic means this fuse is designed to protect power semiconductors by interrupting high short-circuit currents quickly while allowing harmless overload currents, ensuring sensitive device protection.
Is this fuse suitable for DC applications?
No, this particular fuse is rated for AC applications only, as indicated in the technical specifications.
How does the striker indication system work?
The striker provides a mechanical indication by popping out when the fuse element blows, allowing quick visual identification of a blown fuse without disassembly.
Can this fuse be used in systems exceeding 700 V AC?
No, the maximum rated voltage for this fuse is 700 V AC (UL) and 690 V AC (IEC). Using it above these voltages may compromise safety and performance.
