Conta-Clip has added variants with large cross-sections to the terminal blocks with screw connection from the SRK series, so that the feed-through terminals are now also available for wire cross-sections from 16 to 120 mm². In total, a connection range of 0.08 to 120 mm² is covered. Up to a connection range of 35 mm², the terminal blocks have a double cross-connection channel for pluggable cross-connectors. Internal screw-type cross-connectors are used for the larger versions. The range of "SRK" protective conductor terminals has been extended to include variants for wire cross-sections from 16 to 70 mm². In the versions up to 35 mm², contact is made with the mounting rail by simply snapping it on. To simplify the insertion of the wires, the terminals have an enlarged entry channel. A multi-conductor connection is also possible.
