Phoenix Contact 3211025 PT 2,5/S-QUATTRO-PE Protective Conductor Terminal Block Yellow/Green

The Phoenix Contact 3211025 PT 2,5/S-QUATTRO-PE is a professional-grade protective conductor terminal block engineered for secure and reliable grounding in electrical installations. Designed for industrial control cabinets and distribution systems, this terminal block features a robust construction and a distinct yellow and green color scheme to ensure immediate identification of safety-critical ground circuits. Its advanced design facilitates efficient electrical connectivity while maintaining high safety standards.

Advantages

This terminal block utilizes advanced push-in connection technology, which allows for rapid, tool-free wiring of solid conductors or conductors equipped with ferrules. The compact footprint and front-facing connection orientation are specifically engineered to maximize space efficiency within crowded control panels. Furthermore, the integration into the CLIPLINE complete system ensures compatibility with a wide range of accessories, while the dual-function shaft and additional test connection points simplify maintenance and diagnostic procedures.

Suitable for

• Industrial control cabinets
• Electrical distribution systems
• Grounding applications in automation technology
• Control panels with limited installation space

This terminal block may not be suitable for applications requiring high-current power distribution beyond its specified cross-section range or for environments where extreme vibration or mechanical stress exceeds standard industrial ratings. It is also not intended for use with non-grounding circuit configurations.

Key specifications

• Connection method: Push-in connection
• Number of connections: 4
• Cross-section range: 0.14 mm² to 2.5 mm²
• AWG range: 26 to 12
• Width: 5.2 mm
• Height: 35.3 mm
• Color: Green-yellow
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails

To install the terminal block, snap it onto a standard NS 35/7,5 or NS 35/15 DIN rail. Insert a solid conductor or a flexible conductor with a ferrule directly into the push-in contact point until it is securely locked. To release the conductor, use a standard screwdriver to actuate the release mechanism. Ensure that the wire is stripped to the appropriate length as specified by the manufacturer to guarantee a reliable electrical contact.

What to consider before purchase

• Ensure the conductor cross-section is within the 0.14 mm² to 2.5 mm² range
• Verify that your DIN rail type is compatible with NS 35 standards
• Confirm that the four-connection configuration meets your circuit design requirements

For optimal performance and safety, always ensure that the conductors are properly prepared and fully inserted into the terminal block. Regular inspection of the connections is recommended in environments subject to thermal cycling or mechanical vibration.
