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.
Product Positioning
3RW4026-1BB05 is another version of the Siemens SIRIUS 3RW40 series 3RW4026 basic model, which uses the same electrical specifications as the model, with a rated current of 25A and a controllable 11kW/400V motor.
Core Product Advantages and Features
Electronic soft start control
The motor terminal voltage is gradually increased by electronic control to reduce the instantaneous current surge during startup.
Standard overload protection
Built-in electronic overload relay, suitable for continuous operation loads such as general pumps and fans.
Screw terminal wiring
Both the main circuit and the control circuit use screw terminals, which facilitates wiring and subsequent maintenance.
Simplified fuselage structure
It is a simplified model with an S0 frame, suitable for control box environments with limited installation space.
