Buc,
It is possible, but highly unlikely, that you could have damaged the PDP for one or two outputs. We have found on multiple PDPs, that the terminals for the breakers do not line up with the slots in the PDP cover. If this breaker is easier to insert and remove than the other slots, you are likely missing the terminals inside the PDP. At least one of our PDPs is going back because we can't even see the terminals through the slots.
Yes motor controllers can be run from 30 amp breakers and even 20 amp breakers if you are so inclined. However, the breaker is not a current limiter. I have seen some teams use them as such. A CIM motor will still draw 131 amps in stall even if connected through a 20 amp breaker. (For a short period of time.)
