SIRIUS soft starter S0 25 A, 11 kW/400 V, 40 °C 200-480 V AC/DC 110-230 V screw clamps SIRIUS 3RW40 for standard applications for smooth start-up and stop of three-phase synchronous motors.Continuously start, reduce current peaks, prevent mains voltage fluctuations during start-up, relieve the power supply, reduce the mechanical load in the drive, save space and wiring compared to star-delta starters and frequency converters, maintenance-free switching and easy handling. The integrated bypass enables the very compact design and ensures low heat generation in the control cabinet. Intelligent monitoring functions protect the soft starter from overheating and the motor against overload. You can also limit the current to a set maximum value during power-up. With the integrated remote reset you can quickly and easily remove disturbances from the distance Worldwide approvals (e.g. IEC and UL/CSA) also for explosion-prone applications (ATEX or IEC Ex).The 3RW soft starters are available for n
