The invention refers to a circuit breaker (300A) comprising a vacuum interrupter (301) for a gas insulated switchgear. Moreover, the invention refers to a gas insulated switchgear comprising at least one circuit breaker (300A) and/or a disconnector pole. The circuit breaker (300A) has a vacuum interrupter (301) comprising a first movable contact (302), a second stationary contact (303) and a first center axis (304). Moreover, the circuit breaker (300A) comprises a first insulator (305), a contact unit (306) arranged at the first insulator (305), wherein the first movable contact (302) can be moved towards the contact unit (306) so as to be connected to the contact unit (306), an electrical conducting unit (307) comprising a first side (308) and a second side (309), wherein the first side (308) and the second side (309) are opposite to each other, wherein the vacuum interrupter (301) is arranged at the first side (308) of the electrical conducting unit (307), and a second insulator (310) wherein the second insulator (310) is arranged at the second side (309) of the electrical conducting unit (307), wherein the second insulator (310) is connected to the second stationary contact (303), wherein the second insulator (310) has a second center axis (311), and wherein the second center axis (311) of the second insulator (310) is parallel to or collinear with the first center axis (304) of the vacuum interrupter (301).

A switchgear having bus transfer current switching capability by a turn and twist mechanism that includes a contact system for electrical current conduction and bus transfer switching is provided. The contact system has fixed and movable contact assemblies. Each contact assembly includes main contacts and arcing contacts. The arcing contacts are for bus transfer switching. The movable contact assembly includes a current path pipe and an end piece. The current path pipe is a cylindrical pipe, and the end piece is a rectangular block. The movable contact assembly includes a movable main contact provided on the rectangular block, and a movable arcing contact provided at the end of the cylindrical pipe on a portion about the periphery. During engagement, the cylindrical pipe turns about a first axis to bring the contact assemblies proximal to each other, and twists about a second axis for engagement of the main contacts.
