Why Choose the TE Connectivity ZS4-D1 1SNK505211R0000 Double Deck Terminal Block?
The TE Connectivity ZS4-D1 1SNK505211R0000 is a compact and reliable double deck screw clamp terminal block designed for space-efficient power and signal wiring in industrial control panels, switchgear and automation systems. As part of the TE Connectivity ENTRELEC SNK series, the ZS4-D1 combines two connection levels with a single feed-through circuit, enabling one electrical potential to be distributed across four independent screw clamp connections.
The ZS4-D1 uses proven screw clamp connection technology to provide secure conductor termination while simplifying installation and maintenance. Its double deck construction helps panel builders increase connection density without unnecessarily increasing DIN rail length, making it particularly useful for compact machinery and densely populated electrical cabinets.
With a rated cross-section of 4 mm², an IEC rated current of 29 A and an IEC rated voltage of 800 V, the ZS4-D1 provides dependable performance for industrial power and signal circuits. Its narrow 5.2 mm spacing, grey polyamide housing and standard DIN rail mounting make it a practical solution for professional control-panel construction.
