Siemens SIRIUS SOFT STARTER,SIZE S3,106A,24V

SIRIUS Soft Starter S3 106 A, 55 kW/400 V, 40 °C AC 200-480 V, AC/DC 24 V screw terminals. The SIRIUS 3RW30 soft starter is designed for standard applications to provide a smooth start for three-phase asynchronous motors. It allows for stepless 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 enables a very compact design and ensures lower heating in the control cabinet. The soft starter has worldwide approvals (e.g., IEC and UL/CSA) and is available for networks up to 690 V across a wide power range with different control supply voltages, both with screw and spring-loaded connections. 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 provide thermistor motor protection. With the optional connection module, the soft starters can be mounted on circuit breakers, including those with spring-loaded connections. Simple, efficient, always up to date - the SIRIUS system modular concept.
