UKK junction boxes support multiple wire formats.

The single pole distribution block connector offers wiring capacity ranging from 0.2mm² to 4mm², even capable of connecting two conductors of the same cross-section. This provides a foundation for interface adaptation to various conductor sizes.

The modular distribution block connector's design, featuring screw connections, a double-layer terminal block layout, and DIN rail mounting, creates a multi-format acceptance channel suitable for both rigid and flexible conductors, with and without plastic insulation. The terminal block 250a connector, through a standardized clamping mechanism and standardized stripping length (e.g., 8mm stripping), allows for the standardized connection of different conductor sizes within the same terminal block.
