Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR characteristic indicates that this fuse is a partial-range semiconductor fuse designed to protect power semiconductors by interrupting overcurrents quickly while allowing short-duration inrush currents.
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 striker indication system provides a mechanical signal when the fuse has operated, allowing for quick visual identification of a blown fuse without disassembly.
Can this fuse be used in systems exceeding 700V?
No, this fuse is rated for a maximum voltage of 700V AC (UL) and 690V AC (IEC). Using it beyond these limits is not recommended.
