If you see the HRC fuse name plate. Its shown ampere rating
shown which is in many KA (like 80KA and so on). any body
explain what is meaning of this value?

Answer Posted / william lobo

I understand your predicament. But you will only have to
see the 100A which is written in your case and this is the
capacity of the fuse.

80KA is the rupturing capacity of the fuse which is not for
you but for system designers who want to know these things.
