The Z7.261.2027.0 is a 10-pole insulated cross connector, also known as a jumper bar, designed for potential commoning within Wieland's fasis WKF 4 series terminal blocks. This accessory allows for the quick and safe connection of up to ten adjacent terminal blocks, such as the WKF 4 D1/2/35. As part of the IVB WKF 4 series, it is fully insulated and touch-safe, which eliminates the need for partition plates between jumpered groups of different potentials. It is engineered to carry the same rated current as the terminal block it is used with, up to 35 A and 800 V. Its pluggable design saves significant time during wiring and assembly, providing a reliable solution for creating common potential circuits in control cabinets and distribution panels.
