Infinitely variable Starting, reducing current peaks, avoiding mains voltage fluctuations during start-up, relieving the load on the om supply network, reduction of the mechanical load in the drive, significant space and wiring savings compared to star-delta starters and frequency converters, maintenance-free switching and extremely simple 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. In addition, you can limit the current during startup to an adjustable maximum value. The innovative Soft-Torque function ensures that the motor starts up gently. With the integrated remote reset, you can quickly and easily fix faults remotely. Worldwide approvals (eg IEC and UL/CSA) also for potentially explosive applications (ATEX or IEC Ex). The Basic Performance 3RW50 soft starters are available for mains 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-type terminals. Different device variants are available for analogue 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). SIRIUS 3RW5 soft starters - as flexible as your task.
