Hi,
In Distribution board, I seen kA (SC) rating of 415V 3P 32A MCB as 25kA which is more than designed for the panel (as compare to panel SLD 10kA)
What could be the consequences for selecting higher kA MCB?

Nothing really.
25kA rating in place of 10kA rated MCB is no problem.
If it happens to be other way round, it will have dire consequences.
