ZS16-BL – 16mm SCREW TERMINAL BLUE

Why Choose the TE Connectivity ZS16-BL Blue Terminal Block?

The TE Connectivity ZS16-BL is a robust 16 mm² screw clamp feed-through terminal block designed for secure power and signal connections in industrial control panels, machinery and electrical distribution systems. Part of the TE Connectivity ENTRELEC SNK terminal block series, this blue terminal combines high electrical capacity with a compact 10 mm DIN rail footprint.

The ZS16-BL uses proven screw terminal technology to provide secure, durable conductor termination in demanding industrial environments. Its blue polyamide housing provides clear visual identification within terminal assemblies, while the modular SNK construction supports efficient panel building, circuit organisation and integration with compatible terminal accessories.

With a rated conductor size of 16 mm² / 4 AWG, an IEC current rating of 76 A and an IEC voltage rating of 1000 V, the ZS16-BL is suitable for substantial power and signal circuits. Its single-level, two-position feed-through configuration accepts flexible and rigid stranded conductors from 0.5–16 mm² and mounts directly onto standard TH35 DIN rails.
