Why Choose the TE Connectivity ZK6-OR PI-Spring Feed-Through Terminal Block?
The TE Connectivity ZK6-OR (1SNK708030R0000) is a robust 6 mm² PI-Spring feed-through terminal block designed for fast and dependable conductor termination in industrial control panels, machinery and electrical distribution systems. Part of the TE Connectivity ENTRELEC SNK ZK series, it combines push-in spring connection technology with a compact DIN rail mounting format for efficient panel wiring.
The ZK6-OR provides two connection positions on one level and one electrical circuit. Its PI-Spring connection system supports rapid conductor installation while maintaining consistent spring pressure for reliable electrical contact. The screwless connection principle also eliminates routine terminal screw retightening, helping simplify installation and maintenance in industrial environments.
With a 6 mm² rated cross-section, 41 A IEC rated current and 1000 V IEC voltage rating, the ZK6-OR provides high-performance connectivity within an 8 mm-wide terminal profile. Its orange polyamide housing provides clear visual circuit identification, while compatibility with standard TH35 DIN rails enables straightforward integration into industrial terminal assemblies.

Reliable PI-Spring Connections for Industrial Wiring
PI-Spring terminal technology combines rapid conductor installation with reliable spring-force contact pressure. Suitable conductors can be connected efficiently while the spring mechanism maintains consistent pressure on the conductor, helping provide dependable electrical continuity without the periodic retightening associated with conventional screw-clamp terminals.
The ZK6-OR provides a straightforward feed-through connection between two conductors while accommodating flexible conductors up to 6 mm² and rigid stranded conductors up to 10 mm². Its 8 mm profile, high electrical ratings and DIN rail mounting make it particularly suitable for industrial panels requiring compact but capable power and control connections.
