Hello I wanted to ask some questions about the G120C drive and the protection for it.
I want to control a pump, with the motor rating of 5.5 kW, and according to the sinamics portal, they suggest the G120C drive with the 5.5kW rating the model is " 6SL3210-1KE21-3AF1" , and the circuit breaker that they suggest is "3RV2021-4EA10" , the problem is this circuit breaker is rated at 27 - 32A.
Isn't that a little too high, because I think the current draw of that motor is around 12.5A and I wanted to use "3RV2011-4AA10" that is rated at 10-16A.Can you make a suggestion why is that circuit breaker suggested and what should I use?
Thank you in advance!
