DESCRIPTION

Series 3070-PCM connectors are a combination of straight tab and straight screw connectors and used for mains connection of electrical equipment and many other applications. Depending on the respective specifications, they are available in different pole number and variants. Type 307-PC is designed only with one-tier tabs. Tab connectors are suitable for tab receptacles according to DIN 46247. They are joined with a metal rivet to a package with multiple connections (max. 6 connection per pole), thus resulting in low contact resistances. Due to the numerous and variable assembly combinations at the pole, high connection densities can be achieved. Mounting holes are located at each end. Flexible wires require the use of ferrules and cable lugs. For mixed assemblies, we kindly ask for a scheme according to the example on the next page. For asymmetrical assemblies, it must contain the component orientation. Due to the large variety of different types, article numbers cannot be listed.
