ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Will an American 2-pole brkr function properly if wired to a European 220v 50h sys ?

If the breaker is fitted as part of the building's equipment though, it might be subject to the wiring rules applicable in that locality.

Some European countries (e.g. France) are now specifying that breakers must open the neutral as well. I don't know if that's the case in Italy.
