It does not define, I just draw conclusions from what is written in the article to which I attached a link by connecting to the rating data of electromagnetic switches. Perhaps the conclusion is wrong... I don't know, you'd have to look into it more.
And it defines it in such a way that the breaking capacity in the case of "eski" is the maximum current that the protection can turn off without damaging it (i.e. it still works and does not lose its parameters)
In the case of fuses, according to some sources, it is the highest rms value of the prospective current that the fuse-link is able to interrupt at a certain voltage under given conditions of use and operation; after activation, the inserts should not be damaged to the extent that their replacement is difficult or poses a threat to the service.
