## Summary description

The Siemens SIRIUS 3RW3026-1BB04 is a compact 3-phase soft starter designed for smooth motor starting and stopping. It operates at 200-480V AC with a rated current of 25A and a power capacity of 11kW at 400V. Featuring a 24V AC/DC control supply and S0 frame size, this device reduces mechanical stress and current peaks in industrial motor applications, ensuring reliable performance and extended equipment lifespan.

## Long description

The Siemens SIRIUS 3RW3026-1BB04 is a high-performance 3-phase soft starter engineered to provide controlled acceleration and deceleration for industrial electric motors. By managing the voltage supplied to the motor during startup, this device effectively minimizes mechanical shock and electrical current surges, protecting both the motor and the connected drive components from excessive wear. Its compact S0 design allows for efficient space utilization in control cabinets, making it an ideal solution for modern automation systems requiring reliable motor management.
Advantages
This soft starter offers significant benefits for industrial operations by reducing the mechanical stress typically associated with direct-on-line starting. By smoothing out the torque curve, it prevents damage to belts, gears, and couplings, which leads to lower maintenance costs and longer service intervals. The device is designed for seamless integration into existing control architectures, offering a robust 24V AC/DC control supply that ensures compatibility with standard industrial control circuits while maintaining high operational safety and efficiency.
Suitable for
Conveyor belt systems
Pumps and hydraulic systems
Fans and ventilation equipment
Compressors
Small industrial machinery
When it may not be suitable
This soft starter is not intended for applications requiring high starting torque, as it primarily focuses on voltage reduction during the startup phase. It is also not suitable for heavy-duty starting cycles that require frequent stops and starts or for motors operating outside the specified power and voltage ratings.
Key specifications
Rated operational current: 25A
Power capacity: 11kW at 400V
Operational voltage range: 200-480V AC
Control supply voltage: 24V AC/DC
Frame size: S0
Phase count: 3-phase
How to use
Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is mounted on a standard DIN rail or via screw mounting within an enclosure. Connect the main power lines to the input terminals and the motor leads to the output terminals. Ensure the 24V AC/DC control supply is correctly wired to the control inputs. Once installed, the soft starter manages the ramp-up time automatically, providing a steady increase in voltage to the motor until full speed is achieved.
What to consider before purchase
Verify that the motor power rating matches the 11kW capacity at 400V.
Ensure the control cabinet provides adequate ventilation to dissipate heat.
Check that the 24V AC/DC control voltage is available in your control system.
Confirm the physical dimensions of the S0 frame size fit your mounting space.
Usage recommendations: Regularly inspect the terminal connections for tightness and ensure the cooling vents remain free of dust or debris to maintain optimal thermal performance throughout the operational life of the device.
