1snk505064r0000 – zs4-br [pk=50] brown terminal block

Why Choose the TE Connectivity ZS4-BR 1SNK505064R0000 Brown Terminal Block?

The TE Connectivity ZS4-BR 1SNK505064R0000 is a brown feed-through screw clamp terminal block from the ENTRELEC SNK series, designed for dependable conductor connection and distribution in industrial control panels, machinery and electrical installations. Its compact 5.2 mm spacing helps maximise wiring density while providing a secure screw-clamp connection for a broad range of conductor types.

The ZS4-BR is a single-level, single-circuit, 2-position terminal block designed for mounting on standard TH35-7.5 and TH35-15 DIN rails. The main circuit accommodates flexible conductors from 0.22–4 mm² and rigid stranded conductors from 0.2–4 mm², making the terminal suitable for general-purpose control, automation and distribution wiring.

Rated at up to 32 A and 1000 V IEC, the 1SNK505064R0000 combines a durable polyamide housing with an IP20 protection rating and UL 94 V-0 flammability classification. Its operating temperature range of -55 to +110 °C supports dependable use across demanding industrial environments, while the supplied pack of 50 is convenient for panel building and larger terminal assemblies.
