Energy efficiency

SIRIUS 3RW Soft Starters for efficient engery management

Energy-efficient SIRIUS industrial controls help to minimize consumption and systematically increase efficiency. With our SIRIUS 3RW Soft Starters, you benefit from comprehensive advantages in terms of energy efficient industrial controls


Advantages at a glance

  • Transmission of current values

  • Energy management: energy data collected at a higher level

  • Reduction of load on the power system by avoidance of current peaks

  • Less heat in the cabinet:
    - lower power loss than with use of frequency converters
    - resulting in less cooling and compacter design

  • All sizes equipped with a bypass contactor, resulting in lower power loss than conventional soft starters
