SIRIUS 3RW30 soft starter Basic Performance
The SIRIUS 3RW30 Basic Performance soft starters are suitable for soft starting of three-phase asynchronous motors. Thanks to 2-phase control, not only is the current kept at minimum values in all three phases throughout the entire startup time, but disturbing direct current components are also eliminated. This not only enables the 2-phase starting of motors up to 55 kW (at 400 V) but also avoids the current and torque peaks which occur e.g. with wye-delta starters.


Siemens SIRIUS 3RW30 soft starter features
● Two-phase controlled for standard applications
● Parameterization with rotary potentiometer
● Optional communications interface (PROFINET, PROFIBUS, EtherNet/IP, Modbus)
● Visualization of motor data via optional HMI or analog output
● Integrated motor overload and intrinsic device protection
● Engineering in the TIA Portal
● ATEX/IECEx-certified for use in hazardous areas
