NEMA 5
Enclosures constructed for indoor use to provide a degree
of protection to personnel against incidental contact with the
enclosed equipment; to provide a degree of protection against
falling dirt; against settling airborne dust, lint, fibers, and to
provide a degree of protection against dripping and light splashing
of liquids.

NEMA 4
Enclosures constructed for either indoor or outdoor use
to provide a degree of protection to personnel against incidental
contact with the enclosed equipment; to provide a degree of
protection against falling dirt, rain, sleet, snow, windblown dust,
splashing water, and hose-directed water; and that will be undamaged
by the external formation of ice on the enclosure.

NEMA 7
Enclosures are for indoor use in locations classified as
Class I, Groups A, B, C, or D and shall be capable of withstanding
the pressures resulting from an internal explosion of specified
gases, and contain such an explosion sufficiently that an explosive
gas-air mixture existing in the atmosphere surrounding the enclosure
will not be ignited. Enclosed heat generating devices shall not
cause external surfaces to reach temperatures capable of igniting
explosive gas-air mixtures in the surrounding atmosphere. Enclosures
shall meet explosion, hydro-static, and temperature design tests.
|
NEMA

NEMA 9
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).
