Is it possible to replace the MT400 motor with MT630 motor on NS400 MCCB.

The energy delivered by the MT630 to close the breaker is too high, that will rapidly lead to premature ageing of the 
circuit breaker mechanism and main contacts.
 

So it is not recommended to replace the MT400 motor with MT630 motor on NS400 MCCB.
 
This operation is forbidden because of the excess of energy.
