## Long description

The Siemens Sirius 3RW3036-1BB04 is a high-performance 3-phase soft starter engineered to provide controlled acceleration and deceleration for induction motors. By managing the voltage supplied to the motor during startup, this device effectively minimizes mechanical shock and electrical current surges, extending the operational lifespan of connected machinery and protecting the power grid from sudden load spikes.
Advantages
This soft starter offers a compact footprint that saves valuable space within control cabinets, making it an excellent choice for modern industrial environments. Its robust construction ensures long-term reliability even under demanding conditions. By facilitating a smooth transition from standstill to full speed, it significantly reduces wear on belts, gears, and couplings, while the integrated control supply voltage of 24V AC/DC provides flexibility for various automation control architectures.
Suitable for
Conveyor belt systems
Pumps and ventilation fans
Compressors
Industrial machinery with high inertia loads
This device is not suitable for applications requiring speed control or frequent reversing of the motor direction. It is also not intended for use in heavy-duty starting cycles that exceed the thermal capacity of the soft starter, nor should it be used in environments where the ambient temperature or humidity levels fall outside the manufacturer's specified operating range.
Key specifications
Rated power: 22kW at 400V
Rated operational current: 45A
Control supply voltage: 24V AC/DC
Phase type: 3-phase
Operational voltage range: 200-480V AC
Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is mounted in a vertical position within a control panel to ensure proper heat dissipation. After mounting, connect the main power supply to the input terminals and the motor leads to the output terminals. Ensure the control circuit is wired to the 24V AC/DC terminals before applying power to the system.
What to consider before purchase
Verify that the motor power and current ratings match the soft starter specifications.
Ensure the control voltage supply matches the 24V AC/DC requirement.
Check the available space in the electrical cabinet for proper ventilation.
Confirm the application does not require variable speed control.
For optimal performance and longevity, ensure that the soft starter is installed in an environment with adequate airflow and that all electrical connections are tightened to the specified torque settings. Regularly inspect the unit for dust accumulation and ensure that the surrounding temperature remains within the recommended operating limits.
