1. In symmetrically eathed DC networks 2 pole MCBs can be applied at up to 125 V DC (series connection). Polarity does not have to be considered.
Thus any connection mode is permitted.
2. Back up protection is only required when the prospective short circuit current exceeds the rated breaking capacity.
