Abstract: A circuit breaker includes first and second terminals, first and second interrupters, an interconnection part, an actuator, an operating rod, and a lever system. The first terminal is electrically connected to a fixed contact of the first vacuum interrupter. The second terminal is electrically connected to a fixed contact of the second vacuum interrupter. The interconnection part is configured to be in electrical connection with a movable contact of the first vacuum interrupter and the interconnection part is configured to be in electrical connection with a movable contact of the second vacuum interrupter. The interconnection part is configured to provide a current path between the movable contacts. 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.
