Product Positioning
The 3RW4026-1BB14 is a Siemens SIRIUS 3RW40 series S0 frame soft starter, with a control voltage range of 110-230V AC/DC, a rated current of 25A, and the ability to control 11kW/400V motors. It is suitable for applications with existing 110-230V control circuits.
Core Product Advantages and Features
Wide-range control voltage
The control voltage covers 110-230V AC/DC, eliminating the need for additional control transformer configuration costs.
Electronic soft start
The voltage is gradually increased through electronic control, reducing the instantaneous starting current and mechanical shock.
Standard overload protection
Built-in electronic overload relay provides a basic protection mechanism for motor overload.
Screw terminal installation
Both the main circuit and control terminals use screw-type wiring, which facilitates on-site construction and maintenance.
