The TE Connectivity ZS6-4S-PE 1SNK506152R0000 is a robust green/yellow ground screw clamp terminal block designed for protective earth connections in industrial control panels, machinery and electrical distribution systems. Part of the TE Connectivity ENTRELEC SNK Series, it combines four conductor connection positions with a secure rail contact to provide dependable grounding while conserving valuable DIN rail space.
Designed specifically for protective earth applications, the ZS6-4S-PE provides a direct electrical connection to the mounting rail through its screwless rail contact. This rail connection is non-operator-dependent and securely engages when the terminal block is snapped onto the DIN rail, helping improve installation safety and consistency.
The terminal accepts rigid or stranded conductors from 0.2–6 mm² and flexible conductors from 0.22–6 mm². Its compact 6 mm pitch, four connection positions and green/yellow polyamide housing make it an efficient solution for high-density protective earth wiring in industrial electrical assemblies.
Protective earth terminal blocks provide an essential low-impedance connection between equipment conductors and the grounded DIN rail. The TE Connectivity ZS6-4S-PE uses secure screw clamps for conductor termination together with a screwless rail contact, helping establish a dependable protective earth path without relying on a separate operator-adjusted rail connection.
The ZS6-4S-PE shares the same profile as the corresponding ZS6-4S terminal block, helping maintain aligned marking and consistent terminal assembly geometry. Its four connection positions and compact 6 mm spacing make it particularly suitable for control cabinets requiring multiple protective earth conductors within a limited DIN rail footprint.
