The WAGO 870-407 is a push-in type jumper bar used to connect multiple terminal blocks within a WAGO rail-mounted system. This 7-way jumper bar is insulated and rated for a nominal current of 18A, making it suitable for a variety of industrial applications. Installation is simple: push the jumper bar firmly into the terminal blocks until it is fully inserted. For multipole bars, alternating insertion on the right and left sides ensures proper seating. Two parallel jumper slots can be accommodated in a single terminal block. This component is crucial for creating interconnected circuits and simplifying wiring in electrical panels and control systems.
