Why Choose the TE Connectivity ZK6 PI-Spring Terminal Block?

The TE Connectivity ZK6 (1SNK708010R0000) is a high-performance PI-Spring feed-through terminal block designed for reliable power and signal connections in industrial control panels, machinery and electrical distribution systems. Part of the ENTRELEC SNK Series, it combines compact DIN rail installation with TE Connectivity's PI-Spring connection technology for efficient conductor termination.

PI-Spring technology combines push-in and spring connection principles in one terminal. Suitable prepared rigid conductors and conductors with ferrules can be inserted directly, while flexible conductors can be connected using a screwdriver to operate the spring mechanism. This provides installation flexibility while maintaining secure spring-force electrical contact.

With a nominal conductor size of 6 mm², an IEC rated current of 41 A and IEC rated voltage of 1000 V, the ZK6 is suitable for demanding industrial circuits. Its compact 8 mm spacing, grey polyamide housing and compatibility with standard TH35 DIN rails make it an effective solution for high-density control and distribution panels.

Reliable PI-Spring Connections for Industrial Wiring

The TE Connectivity ZK6 is designed to combine high electrical performance with efficient panel installation. PI-Spring technology supports direct push-in connection for suitable prepared conductors while retaining spring-mode operation for flexible, non-prepared stranded conductors, giving panel builders flexibility when working with different wire types.

Spring-force termination maintains consistent conductor contact without conventional screw tightening, while the terminal's up-front marking area helps improve identification in densely populated panels. Combined with its 41 A IEC current rating, 1000 V IEC voltage rating and standard DIN rail mounting, the ZK6 provides a dependable connection point for industrial power, control and signal circuits.
