Phoenix Contact PTI 6 BU Push-In Installation Terminal Block, Blue, 6 mm², 500V, 41A, DIN Rail

In industrial control panels and building installations, reliable wire termination is critical for safety and uptime. The Phoenix Contact PTI 6 BU installation terminal block solves this challenge with a push-in connection system that accepts solid and flexible conductors without tools, reducing wiring time and ensuring vibration-proof connections. Its compact 6 mm² design fits standard DIN rails, making it ideal for distribution boards, machine building, and HVAC systems.

Who is it for

Electricians, panel builders, and maintenance technicians who need a fast, secure, and maintenance-free connection for power distribution and control circuits. It suits applications where space is limited but performance cannot be compromised.

Main features

• Push-in connection technology: simply insert stripped conductor – no tools required for solid wires.
• High current capacity: rated for 41 A and 500 V (IEC), suitable for power distribution up to 6 mm².
• Three connection points on one potential: allows easy potential distribution and looping.
• Blue housing for clear identification of neutral conductors or specific circuit groups.
• DIN rail mounting on NS 35/7.5 and NS 35/15, compatible with standard enclosures.
• Flammability class V0 (UL 94) and wide temperature range from -60 °C to +105 °C for harsh environments.

Tips

For reliable push-in connections, always strip the conductor to exactly 10 mm and ensure no insulation is trapped. Use a screwdriver to open the clamping spring for flexible conductors without ferrules. The blue colour is ideal for marking neutral conductors in three-phase systems. Combine with end plates and marking tags for a professional panel layout.
