The TE Connectivity ZK2.5-PE, part number 1SNK705150R0000, is a compact 2.5 mm² PI-Spring earth terminal block designed to provide reliable protective earth connections in industrial control panels, machinery and electrical distribution systems. As part of the TE Connectivity ENTRELEC SNK Series, it combines efficient DIN rail installation with dependable spring connection technology.
The ZK2.5-PE uses TE Connectivity's PI-Spring connection system, providing a screwless method of terminating conductors while maintaining consistent contact pressure. Its dedicated ground function establishes the protective earth connection required within DIN rail terminal assemblies, while the standard green and yellow housing enables immediate identification of the protective earth circuit.
Designed for 2.5 mm² nominal wiring applications, the ZK2.5-PE accepts flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm². Its compact 5.2 mm spacing helps maximise terminal density, while compatibility with TH35 DIN rails makes it suitable for modern industrial control and automation installations.
Protective earth terminal blocks provide a dedicated connection between electrical conductors and the equipment grounding system. The ZK2.5-PE is specifically configured for this purpose, combining its protective earth function with PI-Spring technology to provide secure and efficient conductor termination in industrial DIN rail assemblies.
The ENTRELEC SNK Series is designed around compact dimensions, straightforward installation and dependable industrial connectivity. With its green and yellow identification, broad conductor compatibility and robust polyamide construction, the ZK2.5-PE provides a practical earth termination solution for machine builders, panel builders and automation engineers.
