Hi all,
I am curious to know if anyone can provide me with a formula or a rule
that sizes the circuit breaker so the circuit is protected during
inrush currents. The supply is 415VAC, 50Hz. The current comming from
the buildings main distribution panel is around 60 Amps. The
parameters on the motor nameplate are as followed:
415VAC
FLA=37.5 amps
Freq=50Hz
RPM=980
The VFD is a 40 HP AC drive.
Any help would be appreciated?
Kind Regards,
vsdguy
