Abstract – The paper describes the status of the high temperature (HTS) current lead development at the Research Centre Karlsruhe (Forschungszentrum Karlsruhe, FZK). After a brief summary of the results for the 70 kA ITER HTS current lead demonstrator, present projects are described: the HTS current leads for the stellarator Wendelstein 7-X, and those for the satellite tokamak JT60-SA.
