## Summary description

The Siemens 3RW4026 soft starter is designed for the controlled starting and stopping of three-phase asynchronous motors. It features a rated current of 25A and supports motor power outputs of 11kW at 400V and 5.5kW at 230V. This compact device helps reduce mechanical stress and current peaks during motor startup, extending the service life of industrial drive systems and protecting the electrical network.

## Long description

The Siemens 3RW4026 soft starter is a high-performance solution engineered for the smooth starting and stopping of three-phase asynchronous motors. By regulating the voltage supplied to the motor, this device effectively minimizes mechanical shock and electrical current spikes that typically occur during direct-on-line starting. Its compact design and robust construction make it an essential component for industrial drive systems, ensuring reliable operation and enhanced protection for both the motor and the connected mechanical equipment.
Advantages
This soft starter offers significant benefits by reducing the mechanical stress on drive components such as belts, gears, and couplings, which leads to lower maintenance requirements and a longer operational lifespan for your machinery. By limiting inrush currents, it also prevents voltage dips in the electrical network, thereby protecting sensitive equipment and reducing the load on power distribution systems. The integrated electronic motor overload protection provides an additional layer of safety, ensuring that the motor remains within its thermal limits during operation.
Suitable for
Conveyor belt systems
Pumps and hydraulic systems
Fans and ventilation units
Compressors
Centrifuges and mixers
When it may not be suitable
This device is not intended for applications requiring high starting torque, as soft starters reduce voltage and consequently torque during the acceleration phase. It is also not suitable for frequent start-stop cycles that exceed the thermal capacity of the internal power semiconductors.
Key specifications
Rated operational current: 25A
Motor power at 400V: 11kW
Motor power at 230V: 5.5kW
Control supply voltage: 110-230V AC/DC
Operational voltage range: 200-480V AC
Size: S0
How to use
Installation should be performed by qualified personnel in accordance with local electrical regulations. The soft starter is mounted on a standard DIN rail or via screw mounting within a control cabinet. After physical installation, connect the main power supply to the input terminals and the motor leads to the output terminals. The control voltage must be connected to the designated terminals to enable the internal logic. Configuration is performed via the integrated potentiometers to set the starting ramp time and current limit according to the specific load requirements of the motor.
What to consider before purchase
Verify that the motor rated current does not exceed 25A.
Ensure the control voltage matches your existing control circuit (110-230V AC/DC).
Check the available space in the control cabinet for the S0 frame size.
Confirm that the application does not require high starting torque.
Usage recommendations: Always ensure adequate ventilation within the control cabinet to prevent overheating of the soft starter. Regularly inspect the electrical connections for tightness to maintain optimal performance and safety.
