Abstract: A circuit breaker includes first and second terminals, first and second vacuum interrupters, an interconnection part, an actuator, an operating rod, and a lever system. The first terminal is 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 associated with a movable contact of the first and second vacuum interrupters when the circuit breaker is in a closed state. A first end of a first lever arm is coupled to the movable contact, and a second end is coupled to the operating rod. When transitioning from an open to a closed state, the actuator moves the operating rod to move the second end of the first lever arm and the second end of the second lever arm.

Abstract: A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, and a piston. The power out contact comprises first and second parts connected by a leg portion. In a first position, the piston contacts the first part of the power out contact. In a second position, the piston contacts the first part of the power out contact and makes electrical contact with the second part. In a third position, the piston contacts the second part and makes electrical contact with the earthing contact. The piston is configured to move along an axis of the three-position disconnector switch to transition the three-position disconnector switch between the different switch positions.
