I have a Wylex CU which is probably 15-20 years old, 100A capacity. Does
anybody know if current Wylex MCBs will fit e.g.
http://www.screwfix.com/app/sfd/cat/...87979&ts=29445 ? The
current MCBs are all NN i.e. NN30, NN15 models. The CU model number is
NN916.

I need to swap a 15A for a 32A. Yes, I know I could try and call Wylex
but this has a bearing on wiring that I'm doing now, and I thought
someone here might know the answer.

AIUI, the plug in MCBs that you linked to are specifically designed to
act as replacements for the traditional rewireable fuse carriers of the
older wylex CUs. I have only ever come accross one design of this type
so I woud expect the plug in MCBs would fit all older wylex CUs.

(Wylex obviously also make DIN rail mounting MCBs for newer CUs as well).
