Suitable for
Industrial control cabinet wiring

This product is not suitable for terminal blocks outside of the TB Essential series, as the dimensions and mounting mechanisms are specific to this product line. It is also not intended for use in environments where extreme chemical exposure or high-impact physical stress exceeds the material specifications of standard industrial plastic components.
