SIRIUS Soft Starter 200-480 V 113 A, AC 110-250 V screw terminals. The SIRIUS 3RW55 High Performance soft starter is designed for demanding applications to ensure smooth starting and stopping of three-phase asynchronous motors. It offers stepless starting, reduces current peaks, avoids voltage fluctuations during startup, alleviates the load on the power supply network, and decreases mechanical stress on the drive. It 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 reduces 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 startup to a set maximum value. With three-phase control, it is particularly suitable for large motor power and root-3 circuits. The innovative torque control ensures optimal motor acceleration. Easy and quick commissioning is facilitated by 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 24 V or 110-250 V control supply voltages, featuring screw and spring terminals throughout. An analog output and thermistor motor protection are integral components of the High Performance soft starters. Optional plug-in communication modules enable 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.
