## Summary description

The Siemens 3RW3047-1BB04 is a compact 3-phase soft starter designed for smooth motor starting and stopping. It operates at a voltage range of 200-480V AC with a rated current of 106A and a power capacity of 55kW at 400V. Featuring a 24V AC/DC control supply voltage, this S3 size device reduces mechanical stress and current peaks in industrial motor applications, ensuring reliable performance and extended equipment lifespan.

## Long description

The Siemens 3RW3047-1BB04 is a high-performance 3-phase soft starter engineered to provide smooth starting and stopping sequences for industrial electric motors. By managing the voltage ramp-up, this device effectively minimizes mechanical stress on drive components and prevents high current peaks during startup, which helps protect the electrical grid and the motor itself. Designed for efficiency and reliability, this compact unit is built to handle demanding industrial environments while maintaining consistent operational stability.
Advantages
This soft starter offers significant benefits by extending the service life of connected motors and mechanical transmission elements such as belts, gears, and couplings. Its compact S3 size allows for space-saving installation within control cabinets, while the integrated 24V AC/DC control supply voltage ensures compatibility with standard industrial automation systems. By reducing the electrical load during startup, it also helps in maintaining the integrity of the power supply network and reducing overall maintenance requirements for the motor system.
Suitable for
Industrial conveyor systems
Pumps and ventilation fans
Compressors and hydraulic units
Centrifugal machines and mixers
When it may not be suitable
This device is not intended for applications requiring frequent starts and stops at high duty cycles, as it is designed for standard soft-starting operations. It is also not suitable for speed control or braking applications, as it functions strictly as a soft starter for motor acceleration.
Key specifications
Operating voltage: 200-480V AC
Rated operational current: 106A
Power capacity: 55kW at 400V
Control supply voltage: 24V AC/DC
Size: S3
Phase: 3-phase
How to use
Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is mounted in a vertical position within a control cabinet to ensure proper heat dissipation. Connect the main power supply to the input terminals and the motor leads to the output terminals. The 24V AC/DC control signal must be wired to the designated control inputs to initiate the soft-start sequence. Ensure all connections are tightened to the specified torque before applying power.
What to consider before purchase
Verify that the motor power rating matches the 55kW capacity at 400V.
Ensure the 24V AC/DC control voltage is available in your control circuit.
Check that the available space in the cabinet accommodates the S3 frame size.
Confirm the application does not require variable speed control.
Usage recommendations
Regularly inspect the terminal connections for tightness and ensure that the ventilation paths around the soft starter remain clear of dust and debris to prevent overheating during operation.
