Single Pole or 1P + N circuit breakers

(1/12) > >>

made2hack:
Hi all,
I'm currently installing a new electrical panel in my workshop and would like to know whether to use just 1P (1 pole or Live only) circuit breakers? Or 1P + N (Live + Neutral) circuit breakers?
This is for EU, 220-240VAC single phase.

I keep finding conflicting information as most search results seem to come up as 2 Pole variants (used in North America).

Are 1P + N "safer" if you will than just 1P that disconnects just the live? Any advantages?

Thanks,

P.S: The panel will also have a 1P+N 30mA differential before the individual circuits.

Disconnecting the neutral is safer, because it might be live, if it's broken somewhere upstream of the breaker.

made2hack:
So it's just for upstream concerns? But would you also wire a house using the same consideration?

made2hack:
Of course I am assuming that this type 1P + N blows at the same time, I mean the breaker breaks both connections and is not like a 2P where one pole might still be active.

A two pole breaker always blows both at the same time.

Whether it's necessary or not depends on how it's wired and your local regulations. In the UK, the neutral and earth is normally combined in the same conductor up to where it enters most houses, so a single pole breaker is sufficient. I can't comment about other places.
