Pixhawk 2.1, Power Module

Hi

I have been told that the power module which comes with the PH2.1, is rated to 30A.
Now, for most applications, this is too low. But, I wanted to know what happens if we exceed this 30A limit?
Would the part burn up or would it simply be unable to correctly measure the current accurately, above 30A?
Has anybody had any bad experience with the PH2.1 power module, included in the package?
Why have Proficnc included such a low rated power module? I find this baffling.

Thanks
