Abstract
A baffle assembly covering a vent opening in a molded case circuit breaker housing is constructed of two identical platelike elements having integral face protrusions. These elements are stacked in face-to-face relationship with their protrusions in engagement to maintain a narrow space between the element faces. Edge notches are provided to orient the elements so that the perforations of one element are misaligned with respect to the perforations of the other element so that arcing gases do not flow in a straight path through the baffle assembly.
