Description

SIRIUS soft starters 200-480 V 171 A, AC/DC 24 V screw terminals Analogue output SIRIUS 3RW50 Basic Performance soft starters for simple applications for soft run-up and slow-down of DC synchronous motors.
Continuously start, reduce current peaks, prevent mains voltage fluctuations during start-up, relieve the power supply, reduce the mechanical load in the drive, save space and wiring compared to star-delta starters and frequency converters, maintenance-free switching and easy handling. The integrated bypass makes the very compact design possible, saves energy and ensures low heating in the control cabinet. Intelligent monitoring functions protect the soft starter from overheating and the motor against overload. You can also limit the current to a set maximum value during power-up. The innovative soft-torque function ensures gentle engine start-up. With the integrated remote reset you can quickly and easily remove disturbances from the distance Worldwide approvals (e.g. IEC and UL/CSA) also for explosion-prone applications (ATEX or IEC Ex).
The 3RW50 basic performance soft starters are available for networks up to 600 V in a power range of up to 315 kW with 24 V or 110-250 V control supply voltages and are consistent with screw and spring connection. Different equipment versions 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 tried-and-tested 3RW40 series (sizes S6 to S12).
