MCBs

[medsailor1]

I just notice my (Legrand B10 ) MCBs are rated for 230v , there nothing to say there are also rated for DC , are they ok to used ? Or do I need once for DC rating ?

Also am I right to think that B10 means 10A .

they will work as a breaker for DC,but are not built to the same spec as a DC breaker which has bigger contact surfaces and a more robust trip mechanism.
