It operates at a voltage range of 200-480V AC with a rated current of 17.6A and a power output of 7.5kW at 400V. Featuring a 24V AC/DC control supply voltage, this S00 size device reduces mechanical stress and current peaks in industrial motor applications, ensuring reliable and efficient operation in various electrical systems.

## Long description

The Siemens SIRIUS 3RW3018-1BB04 is a high-performance 3-phase soft starter engineered to provide smooth acceleration and deceleration for industrial electric motors. By controlling the voltage supplied to the motor, this device effectively minimizes mechanical stress on drive components and reduces high current peaks during startup. Its compact S00 design makes it an ideal solution for space-constrained control cabinets, ensuring reliable performance in demanding electrical environments.
Advantages
This soft starter offers significant benefits by extending the service life of motors and connected mechanical systems such as belts, gears, and couplings. By preventing abrupt torque surges, it protects the entire drive train from premature wear and tear. The device is highly efficient and easy to integrate into existing control systems, providing a stable and controlled power supply that improves overall operational reliability and reduces maintenance requirements in industrial settings.
Suitable for
Conveyor belt systems
Small pumps and fans
Compressors
Machine tools
Packaging machinery
When it may not be suitable
This soft starter is not intended for applications requiring speed control or high starting torque, as it is designed specifically for soft starting and stopping. It should not be used in heavy-duty applications that exceed its rated power capacity of 7.5kW or in environments with extreme temperatures outside the specified operating range.
Key specifications
Rated operational voltage: 200-480V AC
Rated operational current: 17.6A
Power rating: 7.5kW at 400V
Control supply voltage: 24V AC/DC
Size: S00
Phase: 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 a control panel. Connect the 3-phase power supply to the input terminals and the motor leads to the output terminals. Ensure the 24V AC/DC control signal is correctly wired to the control inputs to initiate the starting sequence. Once powered, the soft starter will automatically manage the voltage ramp-up to the motor based on its internal settings.
What to consider before purchase
Verify that the motor power rating does not exceed 7.5kW at 400V.
Ensure the 24V AC/DC control voltage is available in your control circuit.
Check the physical dimensions of the S00 housing to ensure it fits your enclosure.
Confirm that the application does not require variable speed control.
Usage recommendations
Regularly inspect the terminal connections for tightness and ensure the ventilation around the device is unobstructed to prevent overheating during continuous operation.
