Product Positioning

The 3RW4024-1BB04 is a Siemens SIRIUS 3RW40 series S0 frame soft starter. Its specifications are similar to the 1BB14 version, but the difference is that it adopts a 24V AC/DC control voltage, which is closer to the standard of most PLC control panels.

Core Product Advantages and Features

24V control voltage design

The control voltage is 24V AC/DC, which can be directly used with the standard output module of PLC, reducing the need for additional conversion components.

S0 chassis compact

It shares the same S0 frame size as the 1BB14, saving installation space in the distribution box.

Built-in bypass function

After startup, it automatically switches to bypass contact to reduce the long-term heat load on semiconductor components.

Screw terminal wiring

The standard screw terminal design facilitates wiring installation and subsequent maintenance.
