Why Choose the TE Connectivity ZK2.5-4P PI-Spring Feed-Through Terminal Block?

The TE Connectivity ZK2.5-4P 1SNK705012R0000 is a grey PI-Spring feed-through terminal block designed to distribute or branch four conductors within a compact DIN rail footprint. Part of the TE Connectivity ENTRELEC SNK Series, it combines push-in spring connection technology with four connection positions for efficient industrial power and signal wiring.

The ZK2.5-4P provides four conductor connection positions within a single circuit and single level while occupying only 5.2 mm of DIN rail width. Its PI-Spring connection system enables straightforward conductor insertion while maintaining dependable spring pressure on the conductor, making it well suited to high-density control and automation panels.

With a rated cross-section of 2.5 mm², an IEC current rating of 24 A and an IEC voltage rating of 1,000 V, the ZK2.5-4P provides robust electrical performance in a compact format. Its grey polyamide housing, IP20 protection and UL 94V-0 flammability rating support reliable operation across demanding industrial environments.
