monkee,
The pic is a bit out of focus, but they do seem to be BS EN breakers.
If it was clearer I could tell you exactly.
It does appear to be a type B board the pic as displayed is rotated 90 deg to the install?
Why are you asking?

They are BS EN 60947-2 MCCB's.

The BS number is on them, IEC 60947-2.

Lenny,
Well then if that is true I have quite a few years on you and a mop of hair that would certainly make Francis Rossi & Angus Young jealous!!!

Seen these or similar in China, if so, these are single pole MCCB's, not MCB's...

Ooops to late, that'll teach me to stop for a coffee!! lol!!
