It's written on the side of it, and it's difficult to see from here.

Re: MCCB Breaking Capacity

Something to do with its ability to stop a moving object (the units being force applied to it parallel to ground), at least that's how it was explained to me (although I don't think I trust the lecturer as he didn't have a beard). I think that's why they have maintenance factors (when you can see the MCCB contacts thru the enclosure you should replace the MCCB as its breaking capacity has been compromised)

The following link has a few answers (but there of an electrical nature).
