1snk522060r0000 – zs70-yl

Why Choose the TE Connectivity ZS70-YL 1SNK522060R0000 Feed-Through Terminal Block?

The TE Connectivity ZS70-YL 1SNK522060R0000 is a high-capacity yellow screw-clamp feed-through terminal block designed for demanding power and signal connections in industrial control panels, switchgear, machinery and electrical distribution equipment. Part of the TE Connectivity ENTRELEC SNK series, it combines robust screw-clamp termination with DIN-rail mounting for dependable high-current connectivity.

The ZS70-YL provides one feed-through circuit, one level and two connection positions. Its substantial conductor capacity accommodates flexible conductors from 16–70 mm² and rigid stranded conductors from 16–95 mm², making it suitable for large power conductors where secure mechanical retention and low-resistance connectivity are essential.

With an IEC rated current of 192 A and an IEC rated voltage of 1000 V, the ZS70-YL delivers high electrical capacity in a 22 mm terminal spacing. Its yellow polyamide housing provides clear visual identification, while compatibility with standard TH35 DIN rails supports organised installation in industrial electrical assemblies.
