3RW4056-6BB45 SIEMENS

The SIRIUS 3RW4056-6BB45 soft starter is a highly efficient and reliable solution for smoothly starting three-phase asynchronous motors. This S6 soft starter is designed for motors up to 110 kW at 500 V and can handle a current of 162 A at 40 °C. It operates within a voltage range of 400-600 V AC and requires a 230 V AC control supply voltage. The device utilizes screw terminals for secure and easy electrical connections. By reducing the starting current and torque, the soft starter minimizes mechanical stress on the motor and connected machinery, extending their lifespan. It also prevents voltage dips in the power supply system during motor startup. The 3RW4056-6BB45 offers adjustable parameters for optimized starting and stopping characteristics, ensuring smooth operation and reduced wear. This soft starter is suitable for a wide range of applications, including pumps, fans, compressors, and conveyors. Its compact design and robust construction make it ideal for use in demanding industrial environments. Furthermore, it contributes to energy savings by optimizing motor performance and reducing peak demand.
