Siemens SIRIUS 690V 171A 24V screw soft starter

SIRIUS Soft Starter 200-690 V 171 A, AC/DC 24 V screw terminals. The SIRIUS 3RW55 High Performance soft starter is designed for demanding applications, providing smooth start-up and shut-down of three-phase asynchronous motors. It offers stepless starting, reduces current peaks, prevents voltage fluctuations during start-up, relieves the power supply network, and decreases mechanical stress on the drive. It also provides significant space and wiring savings compared to star-delta starters and frequency converters, features maintenance-free switching, and is extremely easy to handle. The integrated bypass allows for a very compact design, saves energy, and ensures lower heating in the control cabinet. Intelligent monitoring functions protect the soft starter from overheating and the motor from overload. Additionally, you can limit the current during the start-up phase to a set maximum value. With three-phase control, it is particularly suitable for large motor outputs and star-delta circuits. The innovative torque control ensures optimal motor acceleration. Quick and easy commissioning is facilitated through auto-parameterization or an application assistant. Predictive maintenance planning is supported by condition monitoring. A detachable HMI with a color display provides clear measurement and diagnostic information. Global approvals (e.g., IEC and UL/CSA) are available. The High Performance soft starters 3RW55 are available for networks up to 690 V in a power range up to 560 kW, with control supply voltages of 24 V or 110-250 V, and consistently feature screw and spring-loaded connections. An analog output and thermistor motor protection are standard components of the High Performance soft starters. Optional plug-in communication modules allow for connection via PROFINET, PROFIBUS, and Modbus TCP. The built-in HMI module can also be mounted on the control cabinet door. The 3RW55 soft starters replace the proven 3RW44 series. SIRIUS 3RW5 soft starters - as flexible as your task.
