Phoenix Contact ST 6-PE suojamaaliitin, jousiliitin, vihreä-keltainen, 6mm², DIN-kisko

In industrial control panels, reliable grounding is not optional—it is a safety imperative. The Phoenix Contact ST 6-PE protective earth terminal block provides a secure, vibration-resistant connection for protective conductors up to 6 mm². Its spring-cage technology eliminates the need for periodic retightening, ensuring low-maintenance operation even in harsh environments. The green-yellow housing clearly identifies the PE function, reducing wiring errors during installation and inspection.

Who is it for

Electrical engineers, panel builders, and maintenance technicians working with DIN rail assemblies in industrial automation, power distribution, and building infrastructure. This terminal is ideal for applications requiring a compact, high-current PE connection with tool-free push-in wiring for solid conductors or ferruled stranded wires.

Main features

• Spring-cage connection system: push-in termination for solid and ferruled conductors, no special tools required
• Rated for 6 mm² nominal cross-section, supports up to 10 mm² solid conductors
• High current capacity: 41 A (IEC) with 1000 V rated voltage
• Green-yellow insulating housing made of flame-retardant polyamide (UL 94 V0)
• Mounts on standard 35 mm DIN rails (NS 35/7.5 and NS 35/15)
• Wide operating temperature range: -60 °C to +105 °C
• Two connection points plus integrated PE foot for direct grounding to the rail
• Stripping length 12 mm for consistent, reliable terminations

Tips

For stranded conductors without ferrules, use a screwdriver to open the spring clamp before insertion. Ensure the DIN rail is properly grounded to complete the PE circuit. When using ferrules with plastic sleeves, verify that the sleeve does not interfere with the clamping area. Regularly inspect the terminal for signs of overheating or discoloration, especially in high-current applications.
