Hi, I was wondering if anyone has any idea if these mcb's can be replaced with RCBO's in the Crabtree board??
Any help would be much appreciated, Many thanks.

Quick answer is no.

I might have been hasty there was thinking Polestar, so maybe yes.

I was looking to add 2 new circuits to the board for a CPS assessment and just thought RCBO's would be better.

You can get Starbreaker rcbos but they may be a tight fitting in an existing board.

Thanks, might try a couple see if they do. Can always take them back if I get no joy. Cheers!!

So long as they are not the MCBs with the exposed terminal connection inside the board, and these do not look like that version, then the current RCBOs do fit.
The front of the RCBO will stick out forward a lot more but there is only the space inside the board that may be a problem.
