## Long description

The Siemens SIRIUS 3RM1002-1AA04 is a high-performance direct-on-line motor starter engineered for precise and reliable motor control in industrial environments. This compact device integrates advanced hybrid switching technology, combining the benefits of semiconductor switching with the durability of mechanical contacts to ensure long service life and efficient operation. Designed for seamless integration into control cabinets, it offers a robust solution for managing small motors with a power rating of 0.75 kW at 400 V.
Advantages
This motor starter stands out due to its exceptionally compact design, which significantly reduces the space required on a DIN rail compared to traditional contactor-based solutions. The hybrid technology minimizes wear on the internal contacts, leading to increased reliability and reduced maintenance requirements over time. Furthermore, the device provides integrated overload protection, ensuring that the connected motor is safeguarded against thermal stress and operational faults without the need for additional external components.
Suitable for
Industrial automation systems
Conveyor belt control
Small pump and fan applications
Machine tool operations
Control cabinet installations with limited space
When it may not be suitable
This device is not intended for applications requiring motor power exceeding 0.75 kW at 400 V or for systems operating outside the specified 2.0 A current range. It is also not suitable for environments where high-frequency reversing or soft-start functionality is required, as this is a direct-on-line starter.
Key specifications
Rated operational power: 0.75 kW at 400 V
Rated operational current: 2.0 A
Control supply voltage: 24 V DC
Mounting type: DIN rail
Technology: Hybrid switching
How to use
Installation is performed by snapping the unit onto a standard 35 mm DIN rail. Connect the main power supply to the input terminals and the motor leads to the output terminals. The 24 V DC control signal is connected to the designated control terminals to initiate the start and stop commands. Ensure that all wiring is performed in accordance with local electrical regulations and that the device is properly grounded within the control panel.
What to consider before purchase
Verify that the motor power rating matches the 0.75 kW specification.
Ensure a 24 V DC power supply is available for the control circuit.
Check the available space on the DIN rail to accommodate the unit dimensions.
Confirm that the application does not require soft-start or variable speed control.
Usage recommendations
Always ensure that the motor starter is installed in an environment with adequate ventilation to prevent overheating. Regularly inspect the terminal connections to ensure they remain tight and free from oxidation to maintain optimal electrical conductivity.
