Claim Text:
1. A contact assembly for interrupting an electrical current, the contact assembly comprising: an outer field generating element configured to generate a first axial magnetic field (AMF); and an inner field generating element configured to generate a second axial magnetic field (AMF) opposite to the first axial magnetic field (AMF); wherein the inner field generating element is coaxial with the outer field generating element and has a smaller diameter than the outer field generating element, wherein the outer field generating element is cup-shaped and slotted with non-radial slots configured to generate the first axial magnetic field (AMF), wherein the contact assembly further comprises at least one cover element for contacting a further contact assembly, and an inner cover element having substantially a same radial extension as the inner field generating element, wherein at least one of the outer field generating element and the inner field generating element is covered by the at least one cover element, and wherein the inner field generating element is covered by the inner cover element.
