SIRIUS Soft Starter 200-480 V 171 A, AC/DC 24 V spring-loaded terminals Failsafe Soft Starter Failsafe SIRIUS 3RW55 High Performance for demanding safety applications for the gentle start and stop of three-phase asynchronous motors. Stepless starting, reducing current peaks, avoiding voltage fluctuations during startup, relieving the power supply network, reducing mechanical stress on the drive, significant space and wiring savings compared to star-delta starters and frequency converters, maintenance-free switching, and very easy handling. 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 startup to an adjustable maximum value. Thanks to three-phase control, it is particularly suitable for large motor outputs. The innovative torque control ensures optimal motor startup. Simple and quick commissioning through auto-parameterization or application assistant. Predictive maintenance planning through condition monitoring. Removable HMI with color display for clear measurement and diagnostic displays. Worldwide approvals, including for explosion-hazardous applications. The High Performance Failsafe Soft Starters 3RW55 are available for networks up to 600 V in a power range up to 315 kW with 24 V or 110-250 V control supply voltages and consistently feature screw and spring-loaded connections. Analog output and thermistor motor protection are integral parts 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 in the control cabinet door. Soft Starter SIRIUS 3RW5 - as flexible as your task.
