NEMA 4X Type Enclosure Ratings & Defintions Definition: intended for indoor and outdoor use primarily to provide a degree of protection against direct spray of water on the enclosure surface.
Nemaco Notes: Usually, NEMA 4X enclosures, boxes and cabinets tend to be more expensive than most other NEMA 4 enclosures due to the cost of (304, 316) stainless steel materials that contain nickel and chrome for corrosion protection. But the NEMA 4X enclosures, boxes and cabinets offer greater durability and corrosion than the NEMA 4 enclosure (carbon steel and plastic) enclosures. NEMA 4X Type Enclosure Examples A typical example of NEMA 4X enclosure would be a metal box used for electrical controls in a lab or any indoor environment that is dry and there is no dripping pipes and rain. NEMA 4X Enclosures are typically lower cost enclosures made from sheet metal or plastic. So basically it is box the keeps electrical wired away from humans but it does not necessary have any protection against dust, dirt, oil, water, any other fluid.
Nemaco Technical Info - Stainless Steel Corrosion Resistance in the NEMA 4X Enclosure Corrosion is the natural degradation of a material due to atmospheric conditions or other factors. Corrosion is generally defined as dissolution of a material due to a reaction with the surrounding environment. Only metals such as gold and platinum are found in a pure form, normal metals only exist combined with other elements. Corrosion is therefore a natural phenomenon, as nature seeks to combine elements which man has produced in a pure form. More specific: iron occurs naturally as iron ore (FE) wants to combine with oxygen molecules from the air and water and then it will "rust". Carbon steels without any protection will therefore form a coating of rust, which will in a sense protect the rest of the steel and constantly removing the rust exposes a new fresh layer of steel to be chemical decompostion. The corrosion resistance of a stainless steel is dependent on a thin invisible film on the steel surface, the passive film. There are, however, environments that cause permanent breakdown of the passive layer. Under circumstances where the passive layer cannot be rebuilt, corrosion occurs on the unprotected surface. Different media can cause different types of corrosion attack that may vary in nature and appearance, and several forms of corrosion can occur on stainless steels.
Stainless Steel - Corrosion Resistance Stainless steel is the generic name for a number of different steels used primarily because of their corrosion resistance. All stainless steels share a minimum percentage of 10.5% chromium. Chromium is always the deciding factor, although other elements, particularly nickel and molybdenum, are added to improve corrosion resistance. The success of the material is based on the fact that it has one unique advantage. The chromium in the stainless steel has a great affinity for oxygen, and will form a film of chromium oxide on the surface of the steel at a molecular level. The film itself is extremely thin, about 130 Angstroms and one Angstrom is one millionth of a centimetre. This layer is described as passive (does not react or influence other materials), tenacious (clings to the layer of steel and is not transferred elsewhere) and self-renewing (if damaged, more chromium from the steel will be exposed to the air and form more chromium oxide). This means that over a period of years a stainless steel knife can literally be worn away by daily use and will still remain stainless.
