The 76.321.0729.0 is a 7-pole insulated cross connector (jumper bar) designed for use with WKMf 2.5 terminal blocks in electrical interconnect applications. This component provides galvanic isolation between connected terminals while maintaining reliable electrical continuity across multiple poles. The insulated jumper bar is commonly used in control circuits, signal distribution, and industrial automation systems where isolated multi-pole connections are required. It integrates seamlessly with Wieland's modular terminal block systems and supports space-efficient panel layouts.
