## Summary description

The Phoenix Contact 3031267 ST 2,5-TWIN-PE is a high-quality protective conductor terminal block designed for secure electrical grounding in industrial control cabinets. Featuring a spring-cage connection technology, this terminal block ensures reliable contact and vibration resistance. It is suitable for mounting on DIN rails and provides a compact solution for organizing wiring in complex electrical systems.

## Long description

The Phoenix Contact ST 2,5-TWIN-PE protective conductor terminal block is a professional-grade grounding component engineered for reliable electrical safety in industrial control cabinets. This terminal block features advanced spring-cage connection technology, which facilitates rapid installation while maintaining high contact quality and excellent vibration resistance. Designed for efficiency, it allows for the connection of two conductors to a single grounding point, streamlining wiring layouts in complex electrical systems.
Advantages
The primary benefit of this terminal block is its robust spring-cage connection system, which eliminates the need for manual screw tightening and ensures consistent pressure on the conductor regardless of environmental vibrations. Its compact design, with a width of only 5.2 mm, allows for high-density wiring, saving valuable space on DIN rails. The distinct green-yellow color coding ensures immediate identification as a protective conductor terminal, enhancing safety and maintenance efficiency within electrical panels.
Suitable for
Industrial control cabinet grounding
Automation and control systems
Applications requiring vibration-resistant connections
High-density wiring environments
When it may not be suitable
This terminal block is specifically designed for protective earth (PE) grounding applications and should not be used for phase or neutral power distribution. It is not intended for use with conductors exceeding 4 mm² in cross-section or for environments where extreme chemical exposure might compromise the spring-cage mechanism.
Key specifications
Connection method: Spring-cage connection
Number of connections: 3
Cross-section range: 0.08 mm² to 4 mm²
AWG range: 28 to 12
Width: 5.2 mm
Mounting type: NS 35/7,5 and NS 35/15 DIN rails
Color: Green-yellow
How to use
To install the terminal block, snap it onto a standard NS 35/7,5 or NS 35/15 DIN rail until it clicks securely into place. Strip the insulation from your conductor according to the recommended length, then insert the wire into the spring-cage opening using a standard screwdriver to actuate the spring mechanism. Ensure the wire is fully seated to guarantee a secure, vibration-proof connection. The TWIN design allows for two conductors to be connected to the same potential, simplifying the grounding of multiple devices.
What to consider before purchase
Verify that your DIN rail type is compatible with NS 35 standards.
Ensure your conductor cross-section falls within the 0.08 mm² to 4 mm² range.
Confirm that the application requires a protective earth (ground) connection.
Usage recommendations
For optimal performance and safety, always ensure that the DIN rail is properly grounded to the main protective earth bus of the enclosure. Regularly inspect connections in high-vibration environments to maintain system integrity.
