The TE Connectivity ZS6-D1 1SNK506211R0000 is a compact 6 mm² double-deck screw clamp feed-through terminal block designed for efficient potential distribution in industrial control panels, machinery and electrical distribution systems. Part of the ENTRELEC SNK series, it provides four screw connection positions across two levels while occupying only 6 mm of DIN rail width.
Unlike a double-deck terminal with two separate circuits, the ZS6-D1 is configured with one feed-through circuit across four connection positions. This arrangement makes it particularly useful for distributing a common electrical potential to multiple conductors while maintaining a compact, organised terminal assembly.
With an IEC rating of 40 A and 800 V, the ZS6-D1 accepts flexible and rigid stranded conductors from 0.2–6 mm². Its grey polyamide housing, reliable screw termination, IP20 protection and compatibility with TH35 DIN rails make it a robust solution for professional power and signal wiring. The 1SNK506211R0000 is supplied in a pack of 50.
Double-deck terminal blocks allow more conductor connections to be accommodated within a limited DIN rail footprint. The TE Connectivity ZS6-D1 uses two vertically arranged levels and four screw clamps to distribute a single feed-through circuit, making it particularly useful where several conductors need to share the same electrical potential.
The ZS6-D1 combines conductor capacity up to 6 mm² with only 6 mm of terminal spacing, helping panel builders increase wiring density without compromising accessibility. Its 40 A IEC rating, robust screw clamp connections and power-and-signal suitability make it an effective solution for automation, machinery and electrical distribution assemblies.
