Hello. Input on the shield 45A 3 phases. Is it possible to put UZO 63A. Not on sale at 45. Or all the same, put that there are 40 Amps?

    Hello! RCD on 40A does not need to be set, it will turn off. A 63-amp RCD is just right. And the introductory machine for what current is calculated? RCD just needs to be selected more in current than a circuit breaker.

      It’s more likely to burn out than to turn off. But otherwise everything is correct.
