More Information
Summary:An electrical enclosure is configured for passive self-extinguishing arc protection and cooler operation of enclosed equipment. The enclosure has a channeled ventilation system with arc channels in fluid communication with exhaust channels. The arc channels around each phase of the enclosed conductors are of sufficient length to help attenuate an arc. The exhaust channels are placed in communication with the arc channels. The geometry and materials of the arc channels and exhaust channels cause the energy balance of the enclosure to favor passive arc interruption. Ventilation channels may be in fluid communication with the arc channels and the exhaust channels to provide cooling airflows over enclosed power conductors during normal non-arcing operation.
