ZS4-GN – 4mm SCREW TERMINAL GREEN

Why Choose the TE Connectivity ZS4-GN 1SNK505061R0000 Terminal Block?

The TE Connectivity ENTRELEC ZS4-GN 1SNK505061R0000 is a green 4 mm² feed-through screw clamp terminal block from the SNK Series, designed to provide secure and dependable conductor connections in industrial control panels, machinery and electrical distribution equipment. Its compact 5.2 mm pitch combines space-efficient DIN rail installation with an IEC current rating of 32 A and voltage rating of 1000 V.

The ZS4-GN is a single-level, single-circuit terminal block with two connection positions. It accepts flexible conductors from 0.22–4 mm² and rigid stranded conductors from 0.2–4 mm², while its proven screw clamp connection provides secure conductor retention for panel building, machine wiring and industrial automation applications.

Manufactured with a durable green polyamide housing, the terminal block mounts directly onto TH35-7.5 or TH35-15 DIN rail. It provides IP20 protection, a UL 94V-0 flammability rating and an operating temperature range of -55 to +110 °C, making it suitable for demanding industrial electrical installations.
