Protective enclosure for medium and high voltage circuit breakers

摘要

The present invention provides an enclosure for housing a circuit breaker therein which utilizes a flange system to prevent enclosure components from separating from each other when an electrical fault occurs therein. The flange system includes flanges, on enclosure walls and doors, which slide into corresponding channels and interlock therein to prevent the components from separating and hot gases from escaping the enclosure when an electrical fault occurs.
