The TE Connectivity ZS6-BL 1SNK506020R0000 is a compact and dependable blue screw-clamp feed-through terminal block designed for power and signal connections in industrial control panels, switchgear and automation equipment. Part of the TE Connectivity ENTRELEC SNK ZS series, it combines proven screw connection technology with a space-efficient DIN-rail design.
The ZS6-BL provides a single feed-through circuit with two connection positions on one level. Its blue polyamide housing enables clear visual identification within terminal assemblies, while the screw-clamp termination provides secure, serviceable conductor connections for industrial electrical installations.
With a rated cross-section of 6 mm², the ZS6-BL accommodates flexible and rigid stranded conductors from 0.2–6 mm². It carries an IEC current rating of 41 A and an IEC voltage rating of 1000 V, while its narrow 6 mm spacing supports high-density terminal arrangements in control cabinets and machinery.
The ZS6-BL provides a practical way to connect conductors up to 6 mm² within only 6 mm of DIN-rail width. Its screw-clamp mechanism creates a secure electrical connection while retaining straightforward access for installation, inspection and maintenance with standard panel-building tools.
Its 1000 V IEC rating makes the terminal suitable for a broad range of industrial power and signal circuits, including applications requiring compact high-voltage connectivity. The blue housing also enables structured colour coding, helping installers identify circuits quickly within complex terminal assemblies.
