Product information

Description

The Siemens 3RW3028 soft starter is a high-performance solution engineered for the controlled starting and stopping of three-phase asynchronous motors. By managing the voltage supply during the startup phase, this device effectively minimizes mechanical stress on drive components and prevents high current peaks that can destabilize electrical networks. Its robust design ensures reliable operation in demanding industrial environments, contributing to the longevity of your machinery.

Advantages

This soft starter offers a significant reduction in mechanical wear on belts, gears, and couplings by providing a smooth acceleration profile. By limiting the inrush current, it helps to prevent voltage drops in the power supply system, which protects sensitive electronic equipment connected to the same grid. The compact S0 size allows for space-efficient installation within control cabinets, while the integrated control logic simplifies the integration into existing automation systems.

Suitable for

  • Conveyor belt systems
  • Pumps and ventilation fans
  • Compressors
  • Small industrial machinery
  • Centrifugal drives

This device is not suitable for applications requiring high starting torque or frequent switching cycles, as it is designed for standard soft-start requirements. It should not be used in environments where the ambient temperature exceeds the manufacturer's specified limits or where there is excessive vibration or moisture without appropriate protective housing.

Key specifications

  • Rated operational current: 38A
  • Motor power at 400V: 18.5kW
  • Motor power at 230V: 11kW
  • Control supply voltage: 110-230V AC/DC
  • Operating voltage range: 200-480V AC
  • Size: S0

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. Ensure that the control voltage matches the specifications and that the motor leads are correctly connected to the output terminals. Once powered, the soft starter automatically manages the ramp-up process based on the internal factory settings.

What to consider before purchase

  • Verify that the motor's full-load current does not exceed 38A.
  • Ensure the control voltage supply is compatible with the 110-230V AC/DC range.
  • Check available space in the control cabinet for the S0 frame size.
  • Confirm the application does not require heavy-duty starting characteristics.
For optimal performance and longevity, ensure adequate ventilation within the control cabinet to prevent overheating during operation. Regularly inspect terminal connections to maintain electrical integrity.
