Abstract: A superconductive current limiter component with magnetic field triggering has a tubular superconductor element (1) which is connected in electrical parallel with a trigger coil (3), wherein the trigger coil runs from a first end of the tubular superconductor element (1) on one side of the lateral face of the tubular superconductor element (1) in the direction of the second end of the tubular superconductor element (1), is deflected at that point to the other side of the lateral face and runs back in the direction of the first end, and so on.
