## Summary description

The Siemens 3RW3046-1BB04 is a compact 3-phase soft starter designed for smooth motor starting and stopping. It operates with a voltage range of 200-480VAC, a rated current of 80A, and a power rating of 45kW at 400V. Featuring a 24V AC/DC control supply voltage and S3 size, this device reduces mechanical stress and current peaks in industrial motor applications, ensuring reliable performance and extended equipment lifespan.

## Long description

The Siemens 3RW3046-1BB04 is a high-performance 3-phase soft starter engineered to provide smooth starting and stopping 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 power grid and extends the operational life of the connected motor and transmission elements. Its compact S3 size and robust design make it an essential component for modern automation systems requiring reliable motor control.
Advantages
This soft starter offers significant benefits by reducing the mechanical impact on belts, gears, and couplings during motor acceleration. By limiting the starting current, it prevents voltage drops in the supply network, which is particularly beneficial in installations with limited power capacity. The device is designed for easy integration into control cabinets, offering a space-saving footprint while maintaining high operational reliability and efficiency in demanding industrial environments.
Suitable for
Conveyor belt systems
Pumps and hydraulic systems
Fans and ventilation units
Compressors
General industrial machinery with 3-phase motors
When it may not be suitable
This device is not intended for applications requiring speed control or torque adjustment during continuous operation, as it is strictly a soft starter for acceleration and deceleration phases. It is also not suitable for applications requiring high-frequency switching or heavy-duty starting cycles that exceed the thermal capacity of the unit.
Key specifications
Operating voltage: 200-480V AC
Rated operational current: 80A
Power rating: 45kW at 400V
Control supply voltage: 24V AC/DC
Size: S3
Phase count: 3-phase
How to use
Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is mounted in a control cabinet, ensuring adequate ventilation to prevent overheating. Connect the 3-phase power supply to the input terminals and the motor leads to the output terminals. The 24V AC/DC control signal is connected to the designated control terminals to initiate the start command. Once installed, the soft starter manages the voltage ramp automatically based on the internal settings.
What to consider before purchase
Ensure the motor power rating matches the 45kW specification at 400V.
Verify that the 24V AC/DC control voltage is available in your control circuit.
Check that the installation space accommodates the S3 frame size.
Confirm the supply voltage is within the 200-480V AC range.
Usage recommendations: Regularly inspect the terminal connections for tightness and ensure the cooling vents remain free of dust and debris to maintain optimal thermal performance.
