Phoenix Contact PT 4-PE suojamaaliitin, Push-in, 4 mm², vihreä-keltainen

Protective conductor terminal block with push-in connection technology, designed for reliable grounding in industrial control panels and distribution systems. The PT 4-PE provides a secure, tool-free connection for solid and stranded conductors up to 4 mm², ensuring low contact resistance and high mechanical retention. Its green-yellow housing clearly identifies the PE function, while the compact design saves space on the DIN rail.

Advantages

Push-in termination reduces wiring time by up to 50% compared to screw connections. The terminal accepts conductors from 0.2 to 6 mm² (solid) and 0.2 to 4 mm² (stranded), with a stripping length of 8–10 mm. The polyamide housing meets UL 94 V0 flammability standards and operates reliably from -60 °C to 105 °C. Short-circuit current rating of 400 A (1 s) and surge voltage rating of 8 kV ensure safety in demanding applications.
