Google 'Wylex NN' and go to the first TLC link. They seem to sell them on there still. I doubt you'll find anything thats not second hand or surplus stock as that style of MCB is obsolete. The other alternative is MK used to do a conversion kit for there old boards to fit new MCBs. The kit consisted of a length of flexible lead and a unusual shaped piece of copper that took the lead and fitted under the incoming screw of an existing MCB. You then just slotted a new MCB on to the DIN rail at the far end of the board and connected the flexible lead in to the base of the new MCB.

Thanks Dunc. I will go hunt. I need a BSEN60898 as the ZS is too high for the current BS3871 type 2 (I think max is 0.87 off the top of my head). The wire is 2.5mm/1mm RFC and produces a ZS of 1.11
(R1+R2 of 0.70 + ZE of 0.41)

Update: Ok, rang Wylex - they say you can still get the NB although 32a and they are BSEN60898 so if I can find one (off to "wilts") and its true Im sorted, thanks. Dave

Flicking through a few bits on Google i also read that Hager MCBs fit the Wylex NN busbar. I don't know if that's true but worth a shot considering Hager's MCB design hasn't changed since its first inception.

Thanks, yes you were spot on last time Dunc when you said the Hager RCBO that I wanted would fit the old hager board - it did Thanks for your experience.
