NEMA Ratings /IP Conversion Chart
Fibox understands that today’s business is global, and understanding the IP ratings compared to NEMA can come in handy when selecting a NEMA rated enclosure for your next project.
Knowing if your need is for an indoor or outdoor application can save time and money instead of retooling a project down the road.

| NEMA Rating | IP Equivalent | NEMA Definition | IP Definition | Protection from Liquids |
|---|---|---|---|---|
| 1 | IP10 | NEMA 1 enclosures constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment and to provide a degree of protection against falling dirt. | 1 = Protected against solid objects 50mm in diameter and greater | 0 = Not Protected |
| 2 | IP11 | NEMA 2 enclosures constructed for indoor used to provide a degree of protection to personnel against incidental contact with the enclosed equipment, provide some protection against falling dirt, and provide a little protection against dripping and light splashing of liquids. | 1 = Protected against solid objects 50mm in diameter and greater. | 1 = Protected against vertically falling water drops. |
| 3 | IP54 | NEMA 3 enclosures are constructed for indoor or outdoor used to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, and windblown dust; and that will undamaged by the external formation of ice on the enclosure. | 5 = Protected against dust -limited ingress permitted. | 4 = Protected against water sprayed from all directions – limited ingress permitted. |
| 3R | IP14 | NEMA 3R enclosures are constructed for either indoor or outdoor used to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, and snow; and that will be undamaged by the external formation of ice on the enclosure | 1 = Protected against vertically falling water drops. | 4 = Protected against water sprayed from all directions – limited ingress permitted. |
| 3S | IP54 | NEMA 3S enclosures are constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, and windblown dust; and in which the external mechanism(s) remain operable when ice laden. | 5 = Protected against dust – limited ingress permitted (no harmful deposit). | 4 = Protected against water sprayed from all directions – limited ingress permitted. |
| 4 | IP66 | NEMA 4 enclosures are constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment. NEMA 4X enclosures also provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water. | 6 = Totally protected against dust. | 6 = Protected against strong jets of water from all directions – limited ingress permitted. |
| 4X | IP66 | NEMA 4 X enclosures are constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment. NEMA 4X enclosures also provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, hose-directed water, and corrosion. | 6 = Totally protected against dust. | 6 = Protected against strong jets of water from all directions – limited ingress permitted. |
| 5 | IP52 | NEMA 5 enclosures are constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against settling airborne dust, lint, fibers, and flying debris; and to provide a degree of protection against dripping and light splashing of liquids. | 5 = Protected against dust – limited ingress (no harmful deposit). | 2 = Protected against direct sprays of water up to 15° from the vertical. |
| 6 | IP67 | NEMA 5 enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against hose-directed water and the entry of water during occasional temporary submersion at a limited depth; and that will be undamaged by the external formation of ice on the enclosure. | 6 = Totally protected against dust. | 7 = Protected against the effects of temporary immersion between 15 cm and 1m. Duration of test 30 minutes. |
| 6P | IP67 | NEMA 6P enclosures constructed for either indoor or outdoor use to provide a degree of protection to the personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against hose-directed water, and the entry of water during prolonged submersion at a limited depth; and that will be undamaged by the external formation of ice on the enclosure. | 6 = Totally protected against dust. | 7 = Protected against the effects of temporary immersion between 15 cm and 1m. Duration of test 30 minutes. |
| 12 and 12K | IP52 | NEMA 12 & 12K enclosures constructed (without knockouts) for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against circulating dust, lint, fibers, and flying debris; and against dripping and light splashing of liquids | 5 = Protected against dust – limited ingress (no harmful deposit). | 2 = Protected against direct sprays of water up to 15° from the vertical. |
| 13 | IP54 | NEMA 13 enclosures constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against circulating dust, lint, fibers, and flying debris; and against the spraying, splashing, and seepage of water, oil, and noncorrosive coolants. | 5 = Protected against dust – limited ingress (no harmful deposit). | 4 = Protected against water sprayed from all directions – limited ingress permitted. |
