Z7.280.3027.0 is an insulated cross connector (IVB WKF 2.5-10) designed for use with Wieland WKF 2.5 feed-through terminal blocks featuring spring clamp connections. This connector facilitates electrical bridging between multiple terminal block positions, enabling efficient circuit configuration and signal distribution in modular terminal block assemblies. The product is rated for 0.13–2.5 mm² fine stranded or 0.13–4 mm² solid wire conductors, with a voltage rating of 300 V and a current capacity of 12 A. It is commonly used in industrial control panels, DIN rail-mounted electrical installations, and modular wiring systems where space-saving interconnections and reliable spring-clamp termination are required.
