Sourcing components for wiring up 3 DYN4-T01 servo drives. Based on the documentation (see screenshots), the circuit breaker, noise filter, line reactor, and contactor should be sized to the number of drives. The example has the circuit breaker at 2x the requirement of the other components, with the drives being rated at ~15A, I would expect not to need more than 45A for each component? It makes me wonder what good the breaker is doing since it wouldn't protect anything from letting out the smoke.

In the first diagram, the DYN4-H01 drives require 10A each, for a total of 30A for 3 drives with the filter, reactor, and contactor sized as such. Why is the breaker 60A?
