    mapj1:

    3 phase (4 pole ) RCBOs exist combining an RCD and MCB function,

    Doepke certainly do them  example , as I think do Hagar  (in some configurations).

    When I last looked the Schneider Siemens derived solution was a to suggest a 3 phase MCB, plus an external shunt trip driven by a VIGI

    configured as a residual current sensor, which in comparison is a bit primitive.

    Since then ABB have released  these




    If you don't have an RCD incomer, then you need an outgoing RCBO. Eaton make them, and as Mike suggests, Schneider requires you to combine the RCD and overload components. Either way, they are not cheap.
