The TE Connectivity ZS6-D2 1SNK506210R0000 is a compact 6 mm² double-deck screw clamp feed-through terminal block designed to increase wiring density in industrial control panels, machinery and electrical distribution systems. Part of the ENTRELEC SNK series, it combines two independent feed-through circuits within a single terminal body, helping reduce the DIN rail space required for multi-level wiring.
The ZS6-D2 provides four connection positions, two independent circuits and two levels within a terminal spacing of only 6 mm. Its double-deck arrangement enables two separate electrical circuits to be terminated vertically in the same DIN rail position, making it particularly useful in control cabinets where available installation space is limited.
Rated at 40 A and 800 V to IEC specifications, the ZS6-D2 accepts flexible and rigid stranded conductors from 0.2–6 mm². Its grey polyamide housing, secure screw clamp connections, IP20 protection and compatibility with TH35 DIN rails provide a robust solution for professional industrial power and signal wiring.
Double-deck terminal blocks increase wiring density by stacking separate electrical circuits vertically rather than requiring an individual DIN rail position for each circuit. The TE Connectivity ZS6-D2 incorporates two independent feed-through circuits within a single 6 mm-wide terminal, helping panel builders make more efficient use of available rail space without sacrificing conductor capacity.
Each circuit uses dependable screw clamp termination for secure power and signal connections. With four connection positions, two levels, 40 A IEC current capacity and compatibility with conductors up to 6 mm², the ZS6-D2 is well suited to densely wired machinery, automation cabinets and industrial distribution assemblies.

The ZS6-D2 is a double-deck feed-through terminal block designed to provide two independent conductor circuits within a single DIN rail position for industrial power and signal wiring.
The ZS6-D2 provides two independent circuits across two levels, with four connection positions in total.
The terminal accepts single flexible and rigid stranded conductors from 0.2–6 mm², with capacities varying when ferrules or multiple conductors are used in one screw clamp.
The ZS6-D2 has an IEC current rating of 40 A and an IEC voltage rating of 800 V.
The double-deck construction places two independent feed-through circuits vertically within a 6 mm terminal spacing, helping reduce the DIN rail space required compared with using separate single-level terminals.
The terminal is designed for DIN rail installation and is compatible with TH35-7.5 and TH35-15 mounting rails.
TE Connectivity ENTRELEC SNK terminal blocks provide compact and dependable connection technology for professional industrial wiring, helping panel builders, automation engineers and machine manufacturers create organised, space-efficient and maintainable electrical systems.
