Melty goodness :D

I had exactly the same problem about 2 months back, wish I had taken photos now. Mind you it was Crabtree starbreakers that were affected to me and I'm certain they weren't part of the recall.
I just put it down to a loose connection!

Extra-box thinking maybe, but might it have been an extremely low Ze/ super high scc or would that have blown the casing apart?

Ive had this before in an industrial scenerio though and put it down that, high fault current. Wasnt as bad as that though just melted a hole in the side of the MCB. Burnt out wires in the isloator caused the short circuit.

Can anyone else explain how three MCB's could get fused together like this? And when I say 'fused', I mean even ramming a screwdriver between them couldn't break them apart!

My thoughts are a loose/incorrect connection to the busbar. Mind you, you'd have at least thought they would have tripped long before reaching this state.

Also, note to any of you who come across anything similar, bag it up before it goes in the van otherwise it'll stink to high heaven of the worlds worst and most pungent smell for weeks!
