Do we have the phase unbalance sensitivity in GV2*** range MPCB.
As the GV2 is for the motor application. Standard IEC947-4-1 gives some information about unbalance conditions
which covered by the Tesys GV2 range:
>> First case: if the current is Phase 1 = 1 x In, Phase 2 = 1 x In, Phase 3 = 0,9 x In
The product will not trip.
>> Second case: if the current is Phase 1 = 1,15 x In, Phase 2 = 1.15 x In, Phase 3 = 0 x In
The product will trip within 2 hours.
