Frequently Asked Questions
What does the gR speed/characteristic mean?
The gR characteristic indicates a full-range semiconductor fuse that provides protection against both overload and short-circuit conditions, designed specifically for semiconductor devices.
How does the striker indication system work?
The striker mechanism triggers a visual flag and can activate remote signalling when the fuse blows, allowing quick identification of faulted circuits without disassembly.
Is this fuse suitable for DC applications?
No, this fuse is rated for AC applications only, as specified by the 800VAC IEC rating.
Can this fuse be used in a 100A circuit?
This fuse is rated for 80A maximum; using it in a 100A circuit may lead to nuisance blowing or insufficient protection. Choose a fuse rated appropriately for your circuit current.
