Swapping out these MG MCB's for RCBO's

See here for supporting evidence What can be used as a replacement for the C45N Merlin Gerin Circuit Breaker? - https://www.se.com/us/en/faqs/FA125104/

Good detective work Dave : ) ?

It will be quite a tight fit as the RCBOs are much taller than the MCBs, the original ones for this board were the same height but were more than two modules wide!

I think they should be ok aslong as bottom clears the earth bar

Schneider C60H will fit.

Are you sure they will with the busbar like that??
They are designed for the busbar at the bottom.

Timbo the photo I posted in my last post seems that they are in fact supplied from busbar at top? So should be ok I think?

Sorry, John. Didn't mean to cause confusion. As long as the earth bar doesn't get in the way or come too close you should be OK.
Most of the MG/Schneider boards I've worked on have been vertical 3ph ones with plenty of room.
