Product Positioning

The 3RW4024-1BB14 is a Siemens SIRIUS 3RW40 series S0 frame soft starter with a rated current of 12.5A and 400V, which can be used for a 5.5kW motor. The control voltage is designed to be AC/DC 110-230V.

Core Product Advantages and Features

S0 Compact Chassis

Its compact size makes it easy to install in existing distribution panels, and it is suitable for upgrading and retrofitting motor control boxes with limited space.

Wide control voltage compatibility

The control voltage covers AC/DC 110-230V, which can correspond to the existing control circuits of most industrial power distribution systems.

Built-in bypass and IP20 protection

After startup, it automatically switches to the built-in bypass to reduce semiconductor heat generation and has a basic IP20 protection rating.

Screw terminal wiring

It adopts a standard screw terminal design, which makes construction wiring and maintenance replacement convenient.
