Z7.261.1227.0 is a 2-pole insulated jumper bar (cross connector) designed for use with Wieland Electric WKF 4/35 DIN rail terminal blocks. This component provides electrical interconnection between adjacent terminal positions while maintaining galvanic isolation through its insulated design. The jumper bar is compatible with the WKF 4 series terminal blocks rated for 32 V and 35 A, and supports wire gauges from 0.13 to 6 mm². It is commonly used in industrial control panels, power distribution systems, and electrical installations where modular terminal block configurations require flexible interconnection options. The insulated construction ensures safety and prevents unintended electrical paths in complex wiring schemes.
