Phoenix Contact PTI 6 Installation Terminal Block - Push-in, 6 mm², 3-Potential, Grey/Blue/Yellow-Green

Industrial electricians and panel builders working on DIN rail assemblies often need a reliable, space-saving terminal block for distributing power and grounding within control cabinets. The Phoenix Contact PTI 6 installation terminal block meets that need with push-in connection technology, allowing fast, tool-free wiring of solid conductors up to 10 mm² and stranded conductors up to 6 mm². This three-potential block provides separate L, N, and PE connections in a single compact unit, reducing wiring time and improving organization.

• Nominal voltage (IEC): 400 V
• Nominal current (IEC): 41 A
• Number of potentials: 3 (L, N, PE)
• Number of connection points: 6 (2 per potential)
• Mounting type: DIN rail NS 35/7.5 or NS 35/15
• Insulating material: Polyamide (PA), flammability rating UL 94 V0
• Operating temperature: -60 °C to 105 °C
• Stripping length: 10–12 mm
• Rated surge voltage: 6 kV
• Pollution degree: 3
• Colour coding: Grey (L), Blue (N), Yellow/Green (PE)

Why choose it

The PTI 6 reduces installation time with push-in terminations that require no special tools for solid wires, while still accepting ferruled stranded conductors. Its compact three-potential design saves space on the DIN rail compared to separate feed-through blocks, and the integrated PE connection ensures safe grounding without additional components. The polyamide housing is halogen-free and self-extinguishing, meeting strict fire safety requirements in industrial environments.

Ideal use cases

• Power distribution in control panels and machine building
• Building installation for lighting and socket circuits
• Motor control centers and HVAC systems
• Retrofit projects requiring quick, maintenance-friendly wiring

Good to know

For stranded conductors without ferrules, a screwdriver is needed to open the push-in spring. The block is rated for use in pollution degree 3 environments, making it suitable for industrial settings with conductive dust or occasional condensation. It is part of the Phoenix Contact PTI series, which offers a wide range of accessories such as end covers and marking tags.
