3RM1202-2AA04
The 3RM1202-2AA04 belongs to the Siemens SIRIUS 3RM1 series, with a rated current of 0.4~2A, a power reference of approximately 0.09~0.75kW, a control power supply of 24VDC, and spring-loaded terminals for both the main and control circuits. It provides reversible start-up and electronic overload protection, and features a compact and space-saving design.
Product Positioning
The 3RM1202-2AA04 is a hybrid reversible motor starter from the Siemens SIRIUS 3RM1 series. It has a rated current of 0.4~2A, uses semiconductor starting combined with relay contact operation, and provides forward/reverse switching and electronic overload protection. It is suitable for forward/reverse control of small three-phase motors.
Core Product Advantages and Features
Hybrid switching technology
The system uses semiconductor contactless switching at startup and switches to mechanical relay contacts during operation, balancing smooth startup with energy saving during long-term operation and extending contact life.
Reversible start function
A single device can perform forward and reverse rotation switching of the motor and overload protection, making it suitable for applications such as pumps, valves, and conveyors that require reversing control.
Adjustable electronic overload protection
The overload release current can be adjusted within the range of 0.4~2A, and can be finely adjusted according to the actual rated current of the motor, providing electronic overload protection.
Integrated diagnostic and testing functions
The main body is equipped with LED status indicator lights and a TEST/RESET button, which can quickly determine the operating status, tripping status, etc., and shorten the troubleshooting time.
22.5mm narrow body rail mounting
It adopts standard 35mm DIN rail mounting, and the housing width is only 22.5mm, and the panel configuration saves more internal space in the control box.
Spring-loaded terminal wiring design
Both the main and control circuits use spring-loaded terminals, and the control power supply is 24VDC, which facilitates wiring construction, maintenance, and replacement.
