SIRIUS Soft Starter S2 45 A, 22 kW/400 V, 40 °C AC 200-480 V, AC/DC 24 V. The SIRIUS 3RW30 soft starter is designed for standard applications requiring a gentle start for three-phase asynchronous motors. It allows for smooth starting, reduces current peaks, avoids voltage fluctuations in the power supply 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 ensures a compact design and lower heating in the control cabinet. It has worldwide approvals, such as 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 they come with screw and spring terminals. The 3RW30/40 models also have additional variants with a 24 V control supply voltage. Some of the 3RW40 up to size S3, as well as all 3RW44, also provide thermistor motor protection. With the optional connection module, the soft starters can be mounted on circuit breakers, including variants with spring terminals. Simple, efficient, always up to date - the SIRIUS system modular concept.
