4 Product combinations 4.1 SIRIUS modular system Switching, protecting, and starting motors In order to simplify the assembly of load feeders, the SIRIUS modular system offers standard components that are optimally harmonized and are easy to combine. Just 7 sizes cover the entire performance range up to 250 kW / 300 hp. The individual switching devices can be assembled to form complete load feeders, either using link modules or by mounting directly. For a selection of matching device combinations, e.g. soft starters and motor starter protectors, refer to chapter Technical data [Page 121].
