Abstract: A busbar having a magnetic shielding structure arranged between conductor bars and an outer casing. The magnetic shielding structure includes a first shielding element and a second shielding element each having a U-shaped cross-section. The shielding elements are made of ferromagnetic material and enclose—on opposite sides—conductor bars so that each fin of the first shielding element is at least partially superimposed on a homologous fin of the second shielding element. The shielding elements can consist of anisotropic ferromagnetic strips with oriented grains.
