fasisFunctionDurably and safe ”jumpering“• The DIN rail terminal blocks with tension spring connectionof the fasis product series can be ”jumpered“ usinginsulated cross connectors without screws.• IP 20 protection against accidental contact is guaranteedeven for inserted cross connectors.• Isolation of the electrical and mechanical functions enablesan optimal selection of materials without any compromise.• The current-carrying bar makes it possible to apply the DINrail terminal block‘s rated current to the cross connector.• The contact spring balances the thermal cold flowproperties of the current-carrying bar and thus ensures adurable electrical connection.• Special alloys ensure a low contact resistance and agastight contact area– Current-carrying bar: tin-plated copper– Contact spring: stainless CrNi steelApplicationJumping with a system• For the smart jump potential distribution insulatedcross connectors in 2 to 20 pole designs are available.• „Jumping“ cross connectors are available tointerconnect non-adjacent potentials to link jump.• The power jump power distribution up to 125 A isimplemented using reducing cross connectors– see page 29.Pre-assembly”Jumping“ and distributing potentials• The jumping potential interconnection is created withnotched cross connectors.• The notched cross connectors– can be prepared by the user as required for the appli cationby using the Wieland notching tool, or– can be purchased already pre-assembled from Wieland.• Staggered jumpering with notched cross connectors isonly possible with the fasis WKFN series.FlexibilityIndividually notched cross connectors• The notched cross connectors are prepared individuallyusing the AKW/A notching tool.• In order to easily cut out individual poles the crossconnectors provide a pre-defined cutting edge.• Notched cross connectors will reduce the rated voltageto 400 V.• All cross connectors with several poles provide a predefinedmarking space which enables colored markingof the current and signal flow.31
