3RW4026-1BB15
The SIRIUS 3RW4026-1BB15 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 is mounted with screw terminals and DIN rail. It is suitable for general pump and fan loads.
Product Positioning
The 3RW4026-1BB15 is a standard soft starter 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 the ability to control 11kW/400V motors.
Core Product Advantages and Features
Electronic soft start control
Solid-state electronic components are used to smoothly increase the voltage at the motor terminals, reducing the current surge during startup.
Standard architecture
Without a thermistor input, it covers general application needs with basic electronic overload protection.
Screw terminal wiring
The main circuit and control circuit use screw terminals, which facilitates wiring construction and future maintenance.
Simplified body design
It is a simplified model with an S0 frame, suitable for installations where the control box space is limited.
