IP and NEMA standards

IP and NEMA standards. The NEMA (National Electrical Manufacturers Association) and IP (Ingress Protection) rating systems are used to describe the degree to which a product is protected from water or dust, among other things. The product in question could be a gas detector, a central gas detection controller, or a simple electrical outlet.

The NEMA rating system (NEMA Standard 250) is primarily used in the United States and Canada, whereas the IP rating system (IEC Standard 60529) is used throughout the rest of the world.

The IP rating system only covers protection against the ingress of water and solid objects, whereas the NEMA Rating system also includes corrosion resistance and use in atmospheres containing explosive agents.

IP (Ingress Protection). The IP rating system provides a means of classifying the degree of protection of solids (such as dust) and liquids (like water) that the electrical equipment and stainless steel cabinets must have. The system is recognized in most countries and is included in several standards, including IEC 60529.

The IP is always present in Delvalle enclosures.

For example, a enclosure IP64 is dust tight and protected against water splashed from all directions. Some of our model of enclosures reach up IP67.

NEMA Ratings

There are many NEMA ratings available for enclosures. Below, is a brief explanation of each NEMA rating.

NEMA 4 Water Tight & Dust Tight – Indoors/Outdoors

Type 4 enclosures are intended for general purpose 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 Water Tight, Dust Tight, & Corrosion Resistant – Indoors/Outdoors

Type 4X enclosures are intended for general purpose indoor and 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.

NEMA 12 Industrial Use – Dust Tight & Drip Tight – Indoors

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

Delvalle obtained NEMA certification under UL Agency.

Comparing NEMA and IP ratings. 

This comparison is only approximate, and it is the responsibility of the user to verify the enclosure rating necessary for the given application.

Delvalle have a wide gamma of products with differents types of protecctions, IP and NEMA standards, for example juctions stainless Steel boxes IP67, or modular enclosures titan series NEMA 4X, or our wall cabinet Luxor, as IP66 as NEMA 4X. For any question, our sales managers are available.
