Abstract:
An exemplary vacuum interrupter for a circuit breaker arrangement including a cylindrically shaped insulating part, within which a pair of electrical contact parts are coaxially arranged and surrounded concentrically by the insulating part. The electrical contact parts can be configured to initiate a disconnection arc only between corresponding inner contact elements after starting a disconnection process, and corresponding outer contact elements can be configured to commutate the arc from the inner contact elements to the outer contact elements until the disconnection process is completed, wherein each inner electrical contact element is designed as a TMF-like contact element for generating mainly a transverse magnetic field, and each outer electrical contact element is designed as an AMF-like contact element for generating mainly an axial magnetic field.
