TE Connectivity 1SNK516010R0000 ZS35 is a grey 35 mm² screw clamp feed-through terminal block rated at 125 A and 1000 V IEC for high-current power and signal wiring in industrial DIN rail installations.
Why Choose the TE Connectivity ZS35 35 mm² Screw Terminal?
The TE Connectivity 1SNK516010R0000 ZS35 is a heavy-duty 35 mm² screw clamp feed-through terminal block designed for reliable power and signal connections in industrial electrical panels, machinery and power distribution systems. Part of the TE Connectivity ENTRELEC SNK series, it combines high-current capability with robust screw clamp termination for demanding DIN rail installations.
The ZS35 features a closed terminal block design, eliminating the need for a separate end section while providing optimised mechanical rigidity. Its 16 mm spacing accommodates conductors up to 35 mm², making it particularly suitable for higher-current circuits where dependable conductor retention and efficient panel organisation are required.
Rated at 125 A and 1000 V IEC, the ZS35 supports flexible and rigid stranded conductors from 6–35 mm² / 10–0 AWG. Its grey polyamide housing, UL 94V-0 flammability rating, IP10 protection and wide -55–110 °C operating temperature range provide a robust solution for industrial power distribution, control and renewable energy applications.
