Why Choose the TE Connectivity ZDS4-22-R1 Pluggable Screw Terminal Block?
The TE Connectivity ZDS4-22-R1, part number 1SNK806013R0000, is a compact 4-position pluggable screw-clamp terminal block designed for reliable feed-through connections in industrial control panels, machinery and automation systems. Part of the TE Connectivity ENTRELEC SNK Series, it combines conventional screw-clamp termination with a pluggable connection architecture for convenient installation and maintenance.
The ZDS4-22-R1 provides four connection positions arranged as a single-level, single-circuit terminal. Its pluggable design can simplify equipment assembly, commissioning and servicing by allowing compatible connections to be separated without disturbing the permanent DIN rail wiring, while screw-clamp technology provides a familiar and secure method of terminating industrial conductors.
With an IEC rated voltage of 800 V, an IEC rated current of 29 A and conductor capacity up to 4 mm², the ZDS4-22-R1 provides strong electrical performance in a compact format. Its 6 mm spacing, grey polyamide housing and compatibility with standard TH35 DIN rails make it well suited to modular control and distribution assemblies.
