Nemaco's Technical Reference Section for the
NEMA 9 Enclosure, Box & Cabinet Rating
Definition: Enclosures are intended for indoor use in locations classified as Class II, Groups E, F, or G, and shall be capable of preventing the entrance of dust. Enclosed heat generating devices shall not cause external surfaces to reach temperatures capable of igniting or discoloring dust on the enclosure or igniting dust-air mixtures in the surrounding atmosphere. Enclosures shall meet dust penetration and temperature design tests, and aging of gaskets (if used).
Applications: NEMA 9 enclosures are mostly made of heavy cast iron, cast stainless steel or cast aluminum. The cover flange and the base flange are machined flat and even for a type surface fit. The enclosures are typically used in facortories, chemical refineries, offshore drilling platforms or dusty environment.
Sorry, There is no other NEMA 9 information available.
