1snk505065r0000 – zs4-wh [pk=50] white terminal block

Why Choose the TE Connectivity ZS4-WH 1SNK505065R0000 White Terminal Block?

The TE Connectivity ZS4-WH 1SNK505065R0000 is a white feed-through screw clamp terminal block from the ENTRELEC SNK series, designed to provide secure and organised conductor connections in industrial control panels, machinery and electrical distribution equipment. Its compact 5.2 mm spacing supports space-efficient terminal assemblies while established screw clamp technology provides dependable conductor termination.

The ZS4-WH is a single-level, single-circuit, 2-position terminal block designed for standard TH35-7.5 and TH35-15 DIN rails. It accepts a single flexible conductor from 0.22–4 mm² and a single rigid stranded conductor from 0.2–4 mm², making it suitable for a broad range of control, automation and distribution wiring applications.

Rated at 32 A and 1000 V IEC, the 1SNK505065R0000 combines a durable white polyamide housing with IP20 protection and a UL 94 V-0 flammability rating. Its wide operating temperature range from -55 to +110 °C supports demanding industrial environments, while the supplied pack of 50 is convenient for panel building and larger terminal strip installations.
