I have just been doing some work on a CU which has BS3871 push button MCBs and all I can see on the things is Wylex SK and 6A, how do I tell the type and the breaking capacity

Just had a quick look - the 5A are M1 rated 'type B' 15-45A are M2 rated.
Must be a different OSG to mine have a look at page 71.
The push button 3871 were replaced by BS EN 60898 and have a Ics with a letter M followed by a number 1 1.5 3 etc giving you the rated SCC capacity in ka!
