ABSTRACT:
A vacuum circuit breaker comprises an interrupter for each phase of a three phase electrical system. Each interrupter includes a cylindrical housing for containing circuit breaker contacts. The axes of the housings are vertically disposed and are arranged to define an equilateral triangle. Projecting radially outward from each housing in fixed relation thereto is a rigid fixed contact bus bar connection link and a rigid movable contact bus bar connection link. Ends of the fixed contact bus bar connection links are disposed in a parallel relation in a horizontal plane. Ends of the movable contact bus bar connection links are disposed in a parallel relation in a horizontal plane. Associated pairs of fixed and movable contact bus bar connection links for each interrupter are disposed in vertical alignment. At least the outboard cylindrical housings for the interrupters are adjustably rotatable about their respective axes for setting the distance between parallel ends of successive horizontally aligned bus bar connection links to adjust for a predetermined primary voltage of the electrical system.
