How do you protect the modules SITOP PSU8200 20 A and SITOP modular 40 A in networks badly affected by harmonics?

  • Entry
  • Associated product(s)
In the case of networks badly affected by harmonics we recommend increased protection of the 3-phase power supplies SITOP PSU8200 20 A and SITOP modular 40 A.

The recommendations in the customer documentation with regard to power breaker types and setting values are possibly not adequate.

Use the SIRIUS power breakers 4.5...6.3 A with article number 3RV2011-1GA10 and select the following setting values.
