Product Positioning

The 3RW4026-1BB04 is a Siemens SIRIUS 3RW40 series S0 frame soft starter with a rated current of 25A, capable of controlling an 11kW/400V motor, and a control voltage of 24V AC/DC. It is the most basic and common specification combination in the same series.

Core Product Advantages and Features

24V control voltage

The control voltage is 24V AC/DC, which is compatible with common PLCs and control power supplies, and is easy to integrate.

Electronic soft start

Electronic control is used to gradually increase the motor terminal voltage, thereby reducing starting current and mechanical shock.

Built-in overload protection

Built-in electronic overload relays replace traditional thermal components, improving protection reliability.

Rated 40°C environment

The rated ambient temperature can reach 40°C, which is suitable for general industrial control box installation conditions.

3RW4026-1BB05

The SIRIUS 3RW4026-1BB05 soft starter is a standard version of the 3RW4026 series, with a rated current of 25A. It can control an 11kW/400V three-phase motor, and its screw terminal design makes it easy to install in existing control boxes.

3RW4024-1BB15

The SIRIUS 3RW4024-1BB15 is a simplified soft starter in the 3RW40 series. Its model number is smaller than that of 3RW4026/4027, and it corresponds to a lower motor current rating. It is suitable for smooth starting of three-phase motors such as small pumps and fans.

3RW4024-1BB14

The Siemens SIRIUS 3RW4024-1BB14 soft starter features an S0 frame with a rated current of 12.5A and 400V, suitable for 5.5kW three-phase motors. It supports AC200-480V main circuit and AC/DC110-230V control voltage. It includes built-in bypass contact and IP20 protection, and uses screw terminal wiring. Suitable for smooth starting of small and medium-sized motors.
