The TE Connectivity ZS6-D2-BL 1SNK506220R0000 is a compact blue double deck screw clamp feed-through terminal block designed for high-density industrial wiring. Part of the TE Connectivity ENTRELEC SNK series, it provides two connection levels and four connection positions within a narrow DIN rail footprint, helping panel builders maximise available cabinet space while maintaining organised and accessible wiring.
The ZS6-D2-BL uses proven screw clamp connection technology for secure conductor termination and accommodates both flexible and rigid stranded conductors from 0.2–6 mm². Its double deck configuration provides two independent feed-through circuits, making it particularly useful where multiple power, control or signal connections must be installed within limited DIN rail space.
With an IEC current rating of 40 A, an IEC voltage rating of 800 V and a compact 6 mm terminal spacing, the ZS6-D2-BL delivers dependable electrical performance for demanding industrial applications. Its blue polyamide housing, IP20 protection and TH35 DIN rail compatibility make it a practical choice for professional panel building, machinery and automation systems.
Double deck terminal blocks provide two connection levels within a single DIN rail position, allowing multiple independent circuits to be accommodated without unnecessarily increasing the length of the terminal assembly. This makes them particularly useful in high-density control cabinets where efficient use of DIN rail space and clear organisation of wiring are important.
The ZS6-D2-BL provides two independent feed-through circuits and four connection positions within a compact 6 mm footprint. Combined with conductor capacity up to 6 mm², an IEC current rating of 40 A and an IEC voltage rating of 800 V, it provides a versatile solution for power, control and signal wiring in industrial machinery and automation systems.
