Why Choose the TE Connectivity ZK4-PE-4P 1SNK706152R0000 PI-Spring Earth Terminal?
The TE Connectivity ZK4-PE-4P 1SNK706152R0000 is a compact 4 mm² four-position PI-Spring protective earth terminal block designed for reliable grounding connections in industrial control panels, machinery and automation systems. Part of the TE Connectivity ENTRELEC SNK series, it combines spring-terminal connection technology with a multi-position design for efficient protective earth wiring.
The ZK4-PE-4P provides four conductor connection positions on a single ground circuit, making it particularly useful where several protective earth conductors need to be connected within one compact DIN rail assembly. Its green and yellow polyamide housing provides immediate identification as a protective earth terminal, while the slim 6 mm spacing supports high-density panel construction.
With a rated wire size of 4 mm², the ZK4-PE-4P accepts flexible conductors from 0.5–4 mm² and rigid stranded conductors from 0.5–6 mm². It also provides a short-time withstand current rating of 480 A for 1 s, while compatibility with TH35 DIN rails enables straightforward integration into industrial electrical cabinets and equipment.
