ZS35-BL – 35mm SCREW TERMINAL BLUE

Why Choose the TE Connectivity ZS35-BL 1SNK516020R0000 35 mm² Blue Feed-Through Terminal Block?

The TE Connectivity ZS35-BL 1SNK516020R0000 is a high-capacity 35 mm² screw clamp feed-through terminal block from the ENTRELEC SNK series, designed for secure power and signal connections in industrial control panels, electrical distribution systems, machinery and automation equipment. Its robust screw terminal connection provides reliable conductor retention for demanding industrial wiring applications.

The ZS35-BL provides two connection positions, one circuit and one level within a 16 mm terminal spacing. It accommodates single flexible and rigid stranded conductors from 6–35 mm², while its DIN rail mounting format allows straightforward integration into organised terminal assemblies.

With an IEC rating of 125 A and 1000 V, together with an 8000 V impulse withstand voltage and 4200 A short-time withstand current at 1 s, the ZS35-BL provides robust electrical performance for high-current connections. Its blue polyamide housing, UL 94V-0 flammability rating and wide -55 to +110 °C operating temperature range make it well suited to professional industrial installations.
