Abstract
A molded case circuit breaker housing employs a tri-furcated design that imparts structural stability and manufacturing efficiency. The design provides a separate top cover, mid-cover and base wherein the mid-cover wall height to base wall height ratio is such that the stresses imparted upon the base sidewalls when pressures are exerted, for example, by gaseous discharges are withstood.
