Abstract

A medium or low voltage circuit interrupter includes a housing with a first end cap, a second end cap that comprises a radial bellows, and one or more insulating sidewalls that extends from the first end cap to the second end cap. The end caps and one or more sidewalls provide a vacuum chamber. A fixed contact that extends through an opening of the first end cap and into the vacuum chamber. A moveable contact that extends through an opening of the second end cap and into the vacuum chamber. Multiple such interrupters may be electrically connected in series, positioned a single plane, and actuated by a single actuator.
