However, I'd like some small MCBs to cut out the various low-limit circuits
at some worthwhile point.
A 6A MCB is essentially useless, as the UPS will trip off way before then.
0.5A, 1A, 2A might be of use.

A quick search does not reveal sources of these.
Any thoughts?

Merlin Gerin (Schneider Electric group) do MCBs at least down to 1A:

Whilst the Telemecanique GB2 range goes down to 0.5A (provided the
tripping characteristic is suitable for you):

Many thanks for the links.
I couldn't find these sorts of things at screwfix et al, and diddn't think
of my normal electronics suppliers.
