## Long description

The Siemens 3SU1400-2DA43-3AA0 is a professional-grade support terminal engineered for secure and reliable electrical connections within industrial control panels. As part of the SIRIUS ACT series, this component is specifically designed for grounding applications, featuring a distinct green/yellow color coding that ensures easy identification and compliance with safety standards. Utilizing advanced spring-loaded connection technology, it provides a robust and vibration-resistant interface for electrical conductors, facilitating efficient assembly in various automation and control environments.
Advantages
This support terminal stands out due to its innovative snap-on mounting concept, which allows for rapid installation without the need for specialized tools. The design is optimized for floor mounting, ensuring a stable and secure fit within industrial enclosures. Its high-grade construction ensures durability even in demanding conditions, providing consistent performance while maintaining electrical integrity. The spring-type connection mechanism significantly reduces wiring time and minimizes the risk of loose connections, contributing to overall system reliability and safety.
Suitable for
Grounding applications in industrial control panels
Automation and control systems requiring secure conductor management
Integration into SIRIUS ACT signaling and pushbutton configurations
Environments where vibration resistance and reliable contact are essential
When it may not be suitable
This terminal is specifically designed for grounding purposes and may not be suitable for high-current power distribution applications where larger gauge wiring is required. It is intended for use within the SIRIUS ACT ecosystem and may not be compatible with non-standard mounting enclosures or systems that do not support the specific snap-on interface.
Key specifications
Connection type: Spring-type terminal
Color: Green/Yellow
Mounting method: Floor mounting
