Why Choose the TE Connectivity ZS70 Grey Terminal Block?

The TE Connectivity ZS70 is a heavy-duty 70 mm² screw clamp feed-through terminal block designed for secure high-current power and signal connections in industrial control panels, machinery, power distribution equipment and renewable-energy systems. Part of the TE Connectivity ENTRELEC SNK terminal block series, this grey closed terminal block combines substantial conductor capacity with robust DIN rail construction.

The ZS70 features a closed-block design that eliminates the need for a separate end section while providing optimised mechanical rigidity. Its proven screw clamp connection system provides dependable conductor retention for demanding industrial circuits, while the modular SNK architecture supports organised panel construction and integration with compatible terminal accessories.

With a rated cross-section of 70 mm², an IEC current rating of 192 A and an IEC voltage rating of 1000 V AC, the ZS70 is engineered for substantial electrical loads. The terminal accepts single rigid conductors up to 95 mm², features a 22 mm terminal spacing and mounts on standard TH35 DIN rails, making it suitable for demanding industrial and power-distribution installations.
