wiring a 3 pin 13 amp mains site plug (blue) not domestic!!

From an educational point of view (im in 2nd year of 2330) why does this product have type C MCBs. Wouldnt a type B be a safer solution. I cant think of examples of why you would use a type C in this environment.

Can anyone help me out,
Thanks

This would be used in conjunction with an RCD so the disconnection time of the MCB under earth fault conditions would not be an issue - although, that said, there are trains of thought (including mine) that think an RCD is not a solution for poor Zs (in TN systems)
If the pitches are TT'd the RCD will be compensating for higher Zs anyway which is un-avoidable.
