Why is the sizing of the breaker for Altivar ATV340D22N4 bigger than for ATV340D30N4E?

From 30kw and above, the ATV340 has the same hardware as ATV930. It means it has also dc choke.

ATV340 of 22kW and below are different. That is why 30kW drive ATV340 has lower input current and lower contactor and breaker needed than 22kW drive (with more harmonics).
