Phoenix Contact 3213953 PTI 2,5-L/L Installation Terminal Block 4-Conductor Grey

The Phoenix Contact PTI 2,5-L/L Installation Terminal Block is a professional grey installation terminal block designed for efficient electrical wiring, distribution, and circuit organization in various industrial and building automation systems. Featuring a 4-conductor setup and reliable Push-in connection technology, this component ensures secure and stable connections for modern electrical installations.

Advantages

This installation terminal block facilitates rapid wiring processes thanks to its advanced Push-in connection method, allowing solid conductors and stranded conductors with ferrules to be inserted directly without tools. The inclusion of double function shafts on all levels enhances modularity and flexibility by providing easy potential distribution and testing options. Its compact design with a width of 5.2 mm maximizes space efficiency within control cabinets and distribution boards while maintaining high safety and performance standards.

Suitable for

• Electrical wiring in building automation systems
• Industrial control panel assembly
• Power distribution in electrical enclosures
• Professional electrical installations requiring multi-conductor organization

When it may not be suitable

This terminal block may not be suitable for applications involving wire cross-sections outside the specified range of 0.14 mm² to 4 mm² or AWG 26 to 12. It is also not intended for direct outdoor use without an appropriate weatherproof enclosure.

Key specifications

• Connection method: Push-in connection
• Conductor cross section: 0.14 mm² to 4 mm²
• AWG range: 26 to 12
• Width: 5.2 mm
• Color: Gray
• Mounting type: NS 35/7,5, NS 35/15 DIN rails

How to use

Mount the installation terminal block onto a compatible NS 35/7,5 or NS 35/15 DIN rail inside a suitable distribution enclosure. Prepare the wires by stripping them to the recommended length, and insert solid conductors or flexible conductors equipped with ferrules directly into the Push-in terminal points until fully seated. Utilize the double function shafts for testing or bridging potentials across multiple terminal levels as required by your circuit design.

What to consider before purchase

• Verify that the wire cross-sections fall within the 0.14 mm² to 4 mm² range
• Ensure compatibility with standard NS 35 DIN rails
• Check space requirements in the control cabinet based on the 5.2 mm terminal width
• Confirm that the Push-in connection method aligns with your installation standards

Usage recommendations: Installation and wiring should be performed exclusively by qualified electrical professionals in compliance with relevant safety standards and local regulations. Always disconnect power to the circuit before installing or modifying wiring connections.
