1. In symmetrically eathed DC networks 2 pole MCBs can be applied at up to 125 V DC (series connection). In this case the breaking capactiy is one level higher compared to an
equivalent 1 pole installation. 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.
