NEMA 4 and Other Rated Products

NEMA 4 is not the only rating available for enclosures in non-hazardous locations. There are several different NEMA ratings for specific enclosure "types", their applications, and the environmental conditions they are designed to protect against. Computer Dynamics offers many industrial flat panel display systems configured for various NEMA ratings, including NEMA 4 type. Below is a brief description of our products with NEMA ratings, followed by the definition of the NEMA ratings:

Rating Descriptions

NEMA 1
Type 1 enclosures are intended for indoor use primarily to provide a degree of protection against contact with the enclosed equipment or locations where unusual service conditions do not exist.

NEMA 4
Type 4 enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against windblown dust and rain, splashing water, and hose directed water; and to be undamaged by the formation of ice on the enclosure.

NEMA 4X
Same as NEMA 4 including protection against corrosion.

NEMA 12
Type 12 enclosures are intended for indoor use primarily to provide a degree of protection against dust, falling dirt, and dripping non-corrosive liquids.
