Which contactor to choose to make the ATS from a single-phase generator?
It is necessary to make ABP from a single-phase generator using a contactor with a zero break. Which contactor to choose? Load 20A. I understand that you need 2 normally open contacts and 2 normally closed. Correctly?

Yes, right, you can use such a contactor. Two contacts for zero and phase from the main network, two other contacts - to the generator.
