Abstract
A contact assembly and a vacuum circuit breaker for interrupting an electrical current are disclosed. The contact assembly includes an outer field generating element for generating a first axial magnetic field (AMF), and an inner field generating element for generating a second AMF opposite to the first AMF. The inner field generating element can be coaxial with the outer field generating element and can have a smaller diameter than the outer field generating element. The outer field generating element can be cup-shaped and slotted with non-radial slots to generate the first AMF. The contact assembly can include an innermost conducting element for nominal current conduction and coaxially adjusted with the inner field generating element.
