Product information

Description

The Siemens SIRIUS 3RW4026-1BB04 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, this device effectively minimizes mechanical shock and electrical current spikes, thereby extending the service life of the entire drive system. Its compact S0 design ensures efficient space utilization within control cabinets, making it a reliable solution for demanding industrial environments.

Advantages

This soft starter offers significant benefits by reducing the mechanical stress on belts, gears, and couplings during the startup phase. It helps maintain stable power grid conditions by limiting inrush currents, which prevents voltage dips that could affect other sensitive equipment. The integrated electronic overload protection provides an additional layer of safety for the motor, while the 24V AC/DC control voltage ensures compatibility with standard industrial automation systems.

Suitable for

  • Conveyor belt systems
  • Pumps and hydraulic systems
  • Fans and ventilation units
  • Compressors
  • Small machine tools

When it may not be suitable

This device is not intended for applications requiring high-torque starting or frequent reversing operations. It is also not suitable for use in environments where the ambient temperature or vibration levels exceed the manufacturer's specified technical limits.

Key specifications

  • Rated operational current: 25A
  • Power rating: 11kW at 400V
  • Control voltage: 24V AC/DC
  • Phase count: 3-phase
  • Size: S0
  • Operational voltage range: 200-480V AC

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The unit is designed for DIN-rail or screw mounting within a protected enclosure. After mounting, connect the main power supply to the input terminals and the motor leads to the output terminals. The control circuit must be connected to the 24V AC/DC terminals. Once installed, configure the starting parameters such as ramp-up time and current limit using the integrated potentiometers to match the specific requirements of the connected motor.

What to consider before purchase

  • Verify that the motor power and current ratings match the soft starter specifications.
  • Ensure the control voltage of your PLC or control system matches the 24V AC/DC requirement.
  • Check the available space in your control panel for the S0 size footprint.
  • Confirm the environmental conditions meet the operating temperature requirements.
Usage recommendations: Regularly inspect the terminal connections for tightness and ensure that the ventilation paths around the device remain unobstructed to prevent overheating during operation.
