Product Positioning

The 3RM1001-1AA04 is a hybrid motor starter from the Siemens SIRIUS 3RM1 series. It uses traditional screw terminal wiring and combines semiconductor switching and relay power-saving operation technology, making it suitable for direct starting of small-power three-phase motors.

Core Product Advantages and Features
Hybrid switching technology
The device uses a semiconductor contactless switching mechanism at startup and switches to relay contacts during operation, balancing smooth startup with long-term energy-saving operation.
Screw terminal wiring
Both the main circuit and the control circuit adopt a screw terminal design, which is compatible with existing wiring habits and maintenance procedures.
Streamlined integrated design
A single module integrates starter and overload protection functions, replacing the traditional combination of contactor and protection device, saving control panel space.
Wide range of applications
With a 500V withstand voltage and an adjustable overload setting of 0.1 to 0.5A, it is suitable for various low-power three-phase induction motor applications.
