SIRIUS Soft Starter S0 38 A, 18.5 kW/400 V, 40 °C AC 200-480 V, AC/DC 24 V screw terminals. The SIRIUS 3RW40 soft starter is designed for standard applications to provide smooth starting and stopping of three-phase asynchronous motors. It allows for stepless starting, reduces current peaks, 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, maintenance-free switching, and easy handling. The integrated bypass ensures a compact design and lower heating in the control cabinet. Intelligent monitoring functions protect the soft starter from overheating and the motor from overload. Furthermore, you can limit the current during startup to a set maximum value. With the integrated remote reset, faults can be quickly and easily resolved from a distance. The soft starter has worldwide approvals (e.g., IEC and UL/CSA) and is also suitable for explosion-prone applications (ATEX or IEC Ex). The 3RW soft starters are available for networks up to 690 V in a wide power range with different control supply voltages and are consistently equipped with screw and spring clamp 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 variants with spring clamp connections. The optional fan allows for an even more compact design in the control cabinet. Simple, efficient, always up to date - the SIRIUS system modular concept.
