• New Sirius 3RW5 soft starter generation for the soft starting of three-phase asynchronous motors from 5.5 to 1,200 kW
  • Modern hybrid switching technology for efficient switching, saving energy and ensuring a long service life
  • Variety of applications including pumping, ventilating and compressing as well as moving and processing
  • Comprehensive device range with matching hardware and individual expansions for all requirements

With its Sirius 3RW5 range, Siemens is launching a new generation of soft starters for simple to demanding drive requirements. This comprehensive range of devices for the soft starting of three-phase asynchronous motors from 5.5 to 1,200 kW enables efficient and future-proof machine concepts to be implemented easily and cost-effectively. The new Sirius 3RW5 soft starters are suitable for any drive, they can be easily integrated into the automation system, and they supply data right up to MindSphere, the cloud-based, open IoT operating system of Siemens. Practice-related functions such as automatic parameterization with changing startup characteristics, and integrated properties such as electrical ruggedness in the case of fluctuating line voltages, support smooth operation in a host of applications.
