pouvoir de coupure renforcé en filiation

Can't argue with that. You've got me convinced.

LOL! I remain highly sceptical: the purpose of cascading is not really to improve breaking capacity, so much as to reduce the breaking capacity required; the implication of this claim is that (for some reason) this particular model has higher-than-usual breaking capacity when used in cascaded mode — presumably, the implication is that this therefore lets you, for example, buy the next model down in the range if you are going to be using it in a cascaded system.

Yes I see what you mean. But as I understand it, the whole point of the cascading exercise is to improve the breaking capacity of each circuit breaker. Perhaps the manufacturer is using the old trick of claiming that the product is something special on the grounds that it just does what it's supposed to do anyway. A bit like the old self-deprecating Citroen advert for a 2CV: "Has a fully round wheel at each corner for improved roadholding..."

Doesn't really make sense to me that way round; I can't think that a manufacturer would be vaunting the features of their product that will be improved by using it in cascading; surely it is more plausible to claim that the advantage of this product is that it gives improved breaking capacity WHEN cascading?

Many thanks for your answers, which clarified things considerably. As I understand it from the link provided, the fact of cascading the circuit breakers is what enhances the breaking capacity of each one in the cascade. If that's the case, it would mean that "cascading-enhanced" would not be wrong.
