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.

Abstract: A switchgear includes a switching device, which is driven by a propellant chemical charge or fast acting switch. The switchgear includes a current or fault current detection unit, and an optical sensor unit for light arc or fault light arc detection, without the need of having an auxiliary voltage applied. In order to reduce the closing time of an earthing switch, the electrical circuit of an inductive current detection unit is electrically connected in series with a light sensing switching path, and a current signal directly ignites the propellant chemical charge or fast acting switch by using a limited electronic device.
