Yes it will be 32A per phase. This means that you can apply a total load
of upto 230V x 32A x 3 = 22kW.

Thanks, maximum required is 18A per phase (10kVA UPS)

Type D means that the magnetic trip will operate at between 10x and 20x
the nominal rating (i.e. instantaneous trip at 320 to 640A on any of the
three phases).

Yep thanks, I gleaned that from the specs on Voltimum's web site.

For MCBs (single phase in this case) supplying IT equipment with SMPSUs
with inrush current ranging from 30A/3ms to 80A/20ms is a type B MCB
asking for trouble at times when several (say 10) servers are powered up
simultaneously (e.g before/after a generator test)
