SIRIUS Soft Starter 200-480 V 250 A, AC 110-250 V screw terminals. The SIRIUS 3RW55 High Performance soft starter is designed for demanding applications requiring smooth starting and stopping of three-phase asynchronous motors. It allows for 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 offers significant space and wiring savings compared to star-delta starters and frequency converters, operates maintenance-free, and is extremely easy to handle. The integrated bypass enables 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 startup to an adjustable maximum value. Thanks to three-phase control, it is particularly suitable for large motor power and square 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 through condition monitoring. A detachable HMI with a color display provides clear measurement and diagnostic displays. Worldwide approvals are available. The High Performance soft starters 3RW55 are suitable for networks up to 690 V in a power range up to 560 kW with 24 V or 110-250 V control supply voltages and consistently feature screw and spring terminals. An analog output and thermistor motor protection are integral parts 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 soft starters 3RW55 replace the proven series 3RW44. SIRIUS 3RW5 soft starters - as flexible as your task.
