It features a 4kW AC-3 power rating at 400V and operates on a 24-34V DC control voltage. Equipped with integrated varistor protection and spring-loaded terminals, this S00 size contactor ensures secure connections and efficient control, particularly suitable for PLC-based systems in rail infrastructure.

## Long description

The Siemens 3RT2016-2XB42-0LA2 is a high-performance railway contactor engineered for reliable motor switching under demanding conditions. Designed as part of the SIRIUS modular system, this S00 size contactor provides a robust solution for rail infrastructure and industrial environments where vibration resistance and operational stability are critical. It features an integrated solid-state operating mechanism and a built-in varistor for surge protection, ensuring consistent performance even in fluctuating power environments.
Advantages
This contactor offers exceptional reliability due to its specialized design for extreme ambient conditions, including an extended temperature range. The use of spring-loaded terminals facilitates a fast, maintenance-free, and vibration-proof installation, which is essential for mobile or high-vibration railway applications. Its compact S00 frame size allows for space-efficient panel layouts, while the integrated auxiliary contact simplifies circuit design and reduces the need for additional components. Furthermore, the device is fully compatible with the broader SIRIUS modular system, allowing for seamless integration with other load feeder components.
Suitable for
Railway infrastructure and rolling stock applications
Switching motors in high-vibration environments
PLC-controlled automation systems
Industrial machinery requiring climate-resistant components
When it may not be suitable
This contactor is specifically optimized for railway and extreme industrial environments with a 24-34V DC control voltage. It may not be suitable for standard residential or commercial applications where a different control voltage or standard mounting requirements are preferred. Additionally, it is not intended for high-power loads exceeding its 4kW AC-3 rating.
Key specifications
Frame size: S00
Power rating: 4 kW at 400 V (AC-3)
Rated operational current: 9 A
Control voltage: 24-34 V DC
Auxiliary contacts: 1 NC
Connection type: Spring-loaded terminals
Integrated protection: Varistor
Operating mechanism: Solid-state
How to use
The contactor should be mounted in a control cabinet according to the specified orientation to ensure proper heat dissipation. Connect the control lines to the spring-loaded terminals, which are designed for tool-less insertion of conductors. Ensure that the control voltage applied is within the 24-34V DC range to maintain the specified operating characteristics. The integrated auxiliary contact can be wired directly into your PLC or control logic to monitor the status of the contactor.
What to consider before purchase
Verify that your control system provides a 24-34V DC signal.
Ensure the 4kW power rating is sufficient for your specific motor load.
Confirm that your wiring infrastructure supports spring-loaded terminal connections.
Check available space in your control panel for the S00 frame size.
Usage recommendations
For optimal performance and longevity, ensure that the contactor is installed in an environment that adheres to the manufacturer's temperature and climate specifications. Regularly inspect the spring-loaded connections during routine maintenance to ensure they remain secure, although they are designed to be maintenance-free.
