@Shalvenay You're confusing interrupt rating and rupture rating. Whether or not 10kA can safely be interrupted depends on the load, source and how the fuse is embedded in the design
Rupture can be made sure of with fiber reinforcement and/or non-ionising gas filling, and whether or not the larger design will then also allow interruption of such is a whole different matter
However, at an AC voltage and a standard that allows two cycles of extinction interruption is also not too hard, given the rupture rating
