Enclosure Types
Type 1—Enclosures constructed for indoor use to provide a degree of protection to
sonnel against incidental contact with the enclosed equipment and to provide a
per
degree of protection against falling dirt.
Type 3R—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, and snow; and that will
be undamaged by the external formation of ice on the enclosure
Type 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.
Type 4X—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, hose-directed water, and corrosion
the external formation of ice on the enclosure.
Type 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 flyings;
and to provide a degree of protection against dripping and light splashing of liquids
Type 12—Enclosures constructed (without knockouts) 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 circulating dust, lint, fibers,
and flyings; and to provide a degree of protection against dripping and light splashing
of liquids
Application Note: For applications of disconnecting means in motor circuit applications,
disconnect must be sized based on ampacity per NEC 430-110, but not less than 115%
of Motor Name-Plate current.
; and that will be undamaged by
