• The space required by the compact SIRIUS 3RW40 softstarter is often only about one third of that required by a contactor assembly for wye-delta starting of comparable rating
• This not only saves space in the control cabinet and on the standard mounting rail but also does away completely with the wiring work needed for wye-delta starters
• This is notable in particular for higher motor ratings which are only rarely available as fully wired solutions
• Compact dimensions, short start up times, easy wiring and fast commissioning make themselves felt as clear-cut cost advantages
• The bypass contacts of these softstarters are protected during operation by an integrated solid state arc quenching system
• The new series of devices comes with the polarity balancing control method, which is designed to prevent direct current components in 2-phase controlled softstarters
