Abstract
An arc-resistant electrical enclosure includes an arresting system that permits forced-air cooling of the interior region to occur during ordinary operation of the enclosure while resisting the flow of hot gases, plasma, and flames to the exterior of the electrical enclosure in an arc event or other event. The arresting system advantageously includes a louver apparatus and a cover apparatus that work in conjunction to resist the flow of gases, plasma, and flames to the exterior of the cabinet in an arc event. The louver apparatus includes louvers that can be moved from an open state to a closed state responsive to a predetermined fluid pressure impinging on the louvers. The cover apparatus includes a fire blocking panel that permits fluid flow therethrough during ordinary operation but which, responsive to a flame, initiates a transformation from one state to another state wherein the openings resist the communication of flames therethrough.
