It's a Schneider RCBO. The CU is an old square D QO board that I can still get new (although ecoensive) parts for.
Every circuit I touch is being upgraded to RCBO from the original MCB's. When I moved in, the only RCD's in the place were on the electric shower and one of 4 socket RFC's.
You shouldn't fit Schneider (or any other non-square D) devices to a square D board without the explicit 'OK' from Square D.
All MCBs/RCBOs vent super heated gas when they trip. The manufacturers design them so that that gas is vented away from any parts it may damage or cause fire to. By mixing manufacturers you are probably venting hot gas where it may cause damage.
