Z7.281.7227.0 is a 7-pole insulated cross connector (jumper bar) designed for WK 4/U feed-through terminal blocks manufactured by Wieland Electric. This component features spring clamp connections and is constructed with insulated material to provide electrical isolation between connected circuits. The connector is rated for wire gauges from 0.13 to 1.5 mm² (30-14 AWG) and supports operating voltages up to 400 V/6 kV/3 with a current rating of 17.5 A. The 6 mm pole spacing and M 3 screw specification ensure compatibility with standard DIN rail-mounted terminal block systems. This cross connector is commonly used in industrial control panels, power distribution systems, and electrical interconnect applications where multiple circuits require safe, isolated connections on compact DIN rail installations.
