Z7.287.0327.0 is a 3-pole uninsulated cross connector (jumper bar) designed for use with WK 10/Si U disconnect blocks featuring screw connection terminals. This component is used to interconnect multiple terminal blocks in electrical installations, providing a direct conductive path between adjacent poles without insulation. The connector features 8 mm spacing and M 3 screw terminals, compatible with the WK 10/Si U series of disconnect blocks. It is commonly applied in industrial electrical installations, control panels, and distribution systems where multiple circuits need to be interconnected efficiently. The uninsulated design allows for flexible circuit configuration while maintaining reliable electrical continuity.
