Abstract
A circuit interrupter including a housing having an internal cavity. The internal cavity includes a space at a first end thereof, and includes an internal wall extending from the space to a second end of the housing. A vacuum interrupter is disposed in the space. The vacuum interrupter has at least one movable contact for contacting at least one stationary contact. An operating rod extends through the cavity, and is operable to move the moveable contact. At least one baffle is fixed to the operating rod, and disposed in the cavity. In a preferred embodiment, at least one step is formed in the wall. The step separates a first internal wall section from a second internal wall section, and the first internal wall section is closer to the space than the second internal wall section.
