MCB or MCCB?

[The Ghost]

So what is that test button on it for ?

 

[Rocboni]

If it has 60947-2 then it is not an mcb, if it has 60898 then mcb, well in my eyes anyway.

Hagar appear to have there MCB (80-125A) as both 10 kA BS EN 60898-1 and 10 kA BS EN 60947-2

Matt, out of interest what type of panel is it, not that it matters, just interested?

Yes it is Lee, at a guess, minimum of 40m run mix of clipped direct and buried.

Swap it out for B80, and your just in when you less the 2O% for operating temp.

*you're.

It's worth noting if you used the figures on the NICEIC cheat sheet 0.43 you wouldn't comply. Using the manufacturers data you do. 0.57x0.8=0.456.
