The TE Connectivity ZS16 1SNK510010R0000 is a robust 16 mm² feed-through screw clamp terminal block designed for reliable power and signal connections in industrial control panels, distribution equipment and automation systems. As part of the TE Connectivity ENTRELEC SNK series, it combines secure screw-clamp termination with compact DIN rail mounting and high electrical performance.
This single-level terminal block provides two connection positions and is engineered for straightforward conductor installation and dependable long-term connections. Its polyamide housing, grey identification colour and 10 mm spacing make it well suited to organised terminal assemblies in machinery, switchgear and electrical distribution applications.
With an IEC current rating of 76 A and voltage rating of 1000 V, the ZS16 supports demanding industrial circuits while accepting flexible and rigid stranded conductors up to 16 mm². The terminal mounts directly onto standard TH35 DIN rails and provides IP20 protection when correctly installed.
Feed-through terminal blocks such as the TE Connectivity ZS16 provide a secure connection point between conductors while helping organise wiring inside control cabinets and distribution systems. The screw clamp design applies reliable mechanical pressure to the conductor, supporting stable electrical contact in industrial environments.
The ENTRELEC SNK series is designed for efficient panel building and straightforward DIN rail installation. Its modular construction allows terminal blocks to be arranged alongside compatible accessories, helping engineers create organised, maintainable and space-efficient wiring systems.
