6 MVA transformer secondary is rated for 725V at no load.
The incommer ACB is rated at 690 V, 3200 Amp. Would there
be any effect on performance of ACB due to lower voltage
rating?

ACB is not suitable as transfomer secondary voltage level
is higher than ACB voltage level which cause insulation
failure of the ACB and cause of flash.
