Siemens Soft starter

SIRIUS Soft Starter S00 6.5 A, 3 kW/400 V, 40 °C AC 200-480 V, AC/DC 24 V spring terminals. The SIRIUS 3RW30 soft starter is designed for standard applications for the gentle starting of three-phase asynchronous motors. It allows for stepless starting, reduces current spikes, avoids voltage fluctuations during startup, relieves the power supply network, and decreases mechanical stress on the drive. Additionally, it offers significant space and wiring savings compared to star-delta starters and frequency converters, is maintenance-free, and easy to handle. The integrated bypass enables a very compact design and ensures lower heating in the control cabinet. It has worldwide approvals (e.g., IEC and UL/CSA). The 3RW soft starters are available for networks up to 690 V across a wide power range with different control supply voltages and are consistently equipped with screw and spring terminals. The 3RW30/40 models also have additional variants with 24 V control supply voltage. Some of the 3RW40 up to size S3, as well as all 3RW44, also offer thermistor motor protection. With the optional connection module, the soft starters can be mounted on circuit breakers, even for the variants with spring terminals. Simple, efficient, always up to date - the SIRIUS system modular concept.
