NEMA Enclosure Ratings

All enclosures are designed to protect users from accidental contact with installed electrical components and to protect your equipment from possible theft or tampering. However, in order to better protect your valuable equipment from all possible threats, you should choose an enclosure that is proven to withstand the environmental conditions of your application. High Quality NEMA and IP Rated Enclosures keep your electronics safe during harsh weather conditions, high pressure spray downs, and even temporary submersion. Knowing the final application of your product will help you decide which level of protection is needed.

The National Electrical Manufacturers Association sets industry standards for the safety and reliability of electronic enclosures which are outlined below. If you’d like further information or help deciding which NEMA Rated Enclosure is right for your project, contact one of our experts.

NEMA 1    Enclosures constructed for indoor use to provide a degree of protection to the equipment inside the enclosure against limited amounts of falling dirt.

NEMA 2    Enclosures constructed for indoor use to provide a degree of protection to the equipment inside the enclosure against falling dirt and limited amounts of falling water (dripping and light splashing).

NEMA 3    Enclosures constructed for either indoor or outdoor use to provide a degree of protection against rain, sleet and wind-blown dust, and will remain undamaged by the external formation of ice on the enclosure.

NEMA 3R   Enclosures constructed for either indoor or outdoor use to provide a degree of protection against rain, sleet, wind-blown dust, and will remain undamaged by the external formation of ice on the enclosure. A small drain hole on the bottom allows for ventilation and quick dispersion of any water that may enter the enclosure.

NEMA 3SX    Enclosures constructed for either indoor or outdoor use to provide a degree of protection against rain, sleet, windblown dust and an additional level of protection against corrosion. These enclosures will also allow for operation of external mechanisms when ice laden.

NEMA 4    Enclosures constructed for either indoor or outdoor use with a dust-tight, water-tight seal to protect against windblown particles, rain, splashing water and hose-directed water. Will remain undamaged by the external formation of ice on the enclosure.

NEMA 4X/IP66    Enclosures constructed for either indoor or outdoor use with a dust-tight, water-tight seal to protect against windblown dust and rain, splashing water, hose-directed water, and damage from external ice formation. Plus, an additional level of protection against corrosion. All Integra Enclosures carry a minimum 4X NEMA Rating.

NEMA 5    Enclosures constructed for indoor use to provide a degree of protection against settling airborne dust and fibers and dripping non-corrosive liquids.

NEMA 6    Enclosures constructed for either indoor or outdoor use to protect against hose-directed water, damage from external ice formation, and the entry of water during occasional temporary submersion at a limited depth.

NEMA 6P/IP68    Enclosures constructed for either indoor or outdoor use to provide a degree of protection against hose-directed water, damage from external ice formation, and the entry of water during occasional prolonged submersion at a limited depth. Integra IP 68 rated enclosures can be submerged in up to 6 feet of water for up to 24 hours.

NEMA 12    Enclosures constructed (without knockouts) for indoor use to provide a degree of protection against circulating dust or fibers, falling dirt and dripping non-corrosive liquids.

NEMA 12K    Enclosures constructed (with knockouts) for indoor use to provide a degree of protection against circulating dust or fibers, falling dirt and dripping non-corrosive liquids.

NEMA 13    Enclosures constructed for indoor use to provide a degree of protection against dust, spraying of water, oil, and noncorrosive coolants.
