Bought a pre-assembled split load cons. unit from Screwfix

?id=82204&ts=15099) a couple of months ago.Fitted it and connected everything apart from the light circuits as I was planning to re-wire all of them at a later stage.
Today I finished re-wiring the light circuits, and found out that 4 of the 5 MCBs (the four left-most in the picture) have all failed. They have not been used since the box was bought, and are clearly faulty - switches either up (on) or down (off) result in no contact.
Nothing major (never had a problem with Screwfix in these situations, and I will be very surprise if they don't replace the faulty ones) - just looks a bit strange....
Any thoughts?
