No machine or plant can manage without low-voltage controls: every device – be it a protection, switching, measuring or monitoring device – has to be individually selected, designed and commissioned. This calls for expertise and experience from users in all industry sectors.
SIRIUS modular system - the largest portfolio on the market
The SIRIUS modular system encompasses the largest switching and protection portfolio on the market. Thanks to the wealth of functionality contained within the devices, they can be used in a wide range of different applications. CAx data is available throughout, and users can draw on comprehensive, standard-compliant configuration support. These two features combine to simplify workflows and speed up the electrical engineering process.
What lies behind the system philosophy?
A lot of thought has gone into creating the SIRIUS modular system. Optimally matched and dimensioned products across all sizes support you in your specific application. The SIRIUS modular system provides you with all the devices you need to switch, protect, control and monitor your motors from S00 to S12 – in other words in widths from 45 to 160 mm and in power ratings from 3 to 250 kW. This generation of devices has been radically renewed and features more than 50,000 combination tests and approvals for worldwide deployment. One example of the many combination options is the pre-assembled SIRIUS 3RA21 and 3RA22 load feeders as direct-on-line and reversing starters in three sizes up to 37 kW, which are made up of the 3RV2 motor starter protector and a 3RT2 contactor.
