SIRIUS soft starter 200-480 V 370 A, AC 110-250 V screw terminals analog output soft starter SIRIUS 3RW50 Basic Performance for simple applications for the gentle starting and stopping of three-phase asynchronous motors. Stepless starting, reduction of current peaks, avoidance of mains voltage fluctuations during start-up, relief of the power supply network, reduction of mechanical load in the drive, considerable space and wiring savings compared to star-delta starters and frequency converters, maintenance-free switching and extremely easy handling. The integrated bypass enables the very compact design, saves energy and ensures less heating in the control cabinet. Intelligent monitoring functions protect the soft starter from overheating and the motor from overload. You can also limit the current to an adjustable maximum value during start-up. The innovative Soft-Torque function ensures gentle motor start-up. With the integrated remote reset, you can quickly and easily resolve faults remotely. Worldwide approvals (e.g. IEC and UL/CSA) also for potentially explosive applications (ATEX or IEC Ex).The 3RW50 Basic Performance soft starters 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 with screw and spring-loaded connections. Different device variants are available for analog output and thermistor motor protection.Optional communication modules enable connection via PROFINET, PROFIBUS and Modbus TCP. Various HMI modules are available for installation in the control cabinet door.The 3RW50 soft starters replace the proven 3RW40 series (sizes S6 to S12).SIRIUS 3RW5 soft starters - as flexible as your task.
