Did you check the phase sequence? If there is some ( hydraulic pump; coolant pump ) three phase motor without VFD, it should run to right direction.
Double check the voltages first of all. Yourlooks great, just double and triple check again. It is easy and doesn't take a lot of time and it is most important at this condition.I checked between phases, power was same 403v
Narrow the circle of suspects.
Disconnect the power supply from distribution terminals making the parts of equipment unpowered. Check which part makes the fuse blow.
