Here is a partial list of the NEMA standards that our products adhere to:

NEMA 4 >Type 4 enclosures are 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. They are not intended to provide protection against conditions such as internal condensation or internal icing.

NEMA 4X - Type 4X enclosures are for indoor or outdoor use primarily to provide a degree of protection against corrosion, windblown dust and rain, splashing water, and hose-directed water; and to be undamaged by the formation of ice on the enclosure. they are not intended to provide protection against conditions such as internal condensation or internal icing.
