© Siemens AG 2009 Introduction SIRIUS – the Modular System Family for the Switching, Protect- ing and Starting of Motors In order to simplify the configuration of load feeders, the SIRIUS modular system offers standard components that are optimally coordinated and are easy to combine. Just 7 sizes cover the entire performance range up to 250 kW. The individual switching devices can be easily assembled to form complete load feeders, either using link modules or by mounting directly.
