RCBO for MEMERA 21 CU 100A

[degsy]

Currently upgrading the Shower and installing 10mm cable for 9.5Kw unit I currently have a MEMERA 21 100A CU (not RCD) and would like to fit an RCBO (which seems to be the best option after reading other posts) to the spare position and avoid new CU or additional CU to avoid touching the meter tails and all that. I have done various searches for an MEM RCBO but have come up a blank on tinternet, will any make of RCBO fit the CU or does it have to be brand specific.
CU is fitted with 32 X2 16 X1 and 5 X 2 MCB's (plus spare position) again after reading posts I think a 40/45 RCBO will be ok

expert guidence needed

other makes will work, BUT the physical size is often different so you might have to cut the cover to get the lid on. if you cant find an RCBO that fits, try looking for a MCB and then have a seperate mini CU with just an RCD next to the CU

that's why i use MK

new stuff still fits MK sentry units from the 1980's (with a retrofit / split load kit <£10)
