JUKKB 3 Double Layer Terminal Blocks

Din Rail Double Layer terminal blocks screw wiring 


Feed-through IEC Screw-type Double layer Terminal Blocks are ideal for applications where control signals must be distributed and collected through the same blocks. The blocks are a good solution for high-density wiring applications and are available in nine colors.The double wiring design terminal blocks available without extension of mounting rail. It can reduce the installation costs and speed the wiring. 

◆ The multiple levels screw connection terminal block has the typical features which are decisive for practical applications.

◆ Made from engineering flame resistance nylon PA66, with corrosion proof metal parts.

◆ Combination foot are suitable for Din Rail NS 35mm.

◆ Can use fixed bridges to build electric distribution in the terminal center , or use insertion bridges in the clamping space.

It is safe, environmental, and harmful halogen free. As the elastic deformation of the wire pressing frame increases due to the special structure treatment, the thread friction increases to achieve the self-locking function. Various wires can be connected directly without pre-treatment. The bolt is fabricated from high strength alloy copper, copper cathode for the current bar, and copper alloy for the wire pressing frame.
