WAGO expands its X-COM S MINI rail-mounted terminal block series to include double deck terminal blocks with 3.5 mm pin spacing. These terminal blocks allow the user to connect two potentials through one terminal block, thus saving space on the carrier rail. The new double deck terminal block, combined with a 2-conductor female connector, provides an extremely high connection density. These double deck terminal blocks are designed for conductor cross sections up to 1.5 mm² and a maximum rated current of 13.5 A. All of the terminal blocks can be marked using WMB labels and marking strips.
