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 ?

At each and every hardware store in Austria. You'll find 2 racks side by side, 1 with single pole breakers, 1 with 1+N. About twice the price, but strongly recommended (if not even required). Saves the need for a neutral bus in the panel and makes split arrangements with more than 1 RCD much easier.
