Abstract: The present invention relates to a medium voltage or high voltage circuit breaker; comprising: a first terminal (2); a second terminal (6); a first vacuum interrupter (5); a second vacuum interrupter (5); an interconnection part (9); an actuator (8); an operating rod (11); and a lever system (12). The first terminal is electrically connected to a fixed contact (3) of the first vacuum interrupter. The second terminal is electrically connected to a fixed contact (3) of the second vacuum interrupter. The interconnection part is configured to be in electrical connection with a movable contact (4) of the first vacuum interrupter and the interconnection part is configured to be in electrical connection with a movable contact (4) of the second vacuum interrupter. The interconnection part is configured to provide a current path between the movable contacts. A first end of a first non-linear lever arm (22) of the lever system is coupled to a pushrod (7) of the movable contact of the first vacuum interrupter at a first lever arm first end pivot point, and a second end of the first lever arm is coupled to the operating rod at a centre pivot point. A first end of a second non-linear lever arm (22) of the lever system is coupled to a pushrod (7) of the movable contact of the second vacuum interrupter at a second lever arm first end pivot point, and a second end of the second lever arm is coupled to the operating rod at the centre pivot point. A part at the first end of the first non-linear lever arm is supported by the interconnection part and can slide linearly within a slot of the interconnection part or a part at the first end of the first non-linear lever arm is supported by the interconnection part and can move linearly with respect to a bearing of the interconnection part. A part at the first end of the second non-linear lever arm is supported by the interconnection part and can slide linearly within a slot of the interconnection part or a part at the first end of the second non-linear lever arm is supported by the interconnection part and can move linearly with respect to a bearing of the interconnection part. In a transition from an open state to the closed state the actuator is configured to move the operating rod to move the second end of the first non-linear lever arm and the second end of the second non-linear lever arm such that the part at the first end of the first non-linear lever arm and the part at the first end of the second non-linear lever arm move simultaneously within their corresponding slots away from one another or with respect to their corresponding bearings away from one another.
