Comparison of IP Rating and NEMA

IP00

No protection

NEMA 1

Protects against accidental access to hazardous parts and a limited amount of dust.

IP10

Protection against solid objects larger than 50mm

NEMA 2

 Similar to NEMA 1, but provides enhanced protection against water droplets at inclinations up to 15 degrees

IP11

Protection against solid objects larger than 50mm, protected against vertical water droplets

NEMA 3

Protects against rain, snow, and non-corrosive external dust, suitable for outdoor use.

IP22

Protection against solid objects larger than 12mm, protected against water droplets at angles up to 15°

NEMA 3R

Similar to NEMA 3, but without dust protection. Used for outdoor applications such as electrical enclosures.

IP23

Protection against solid objects larger than 12mm, protected against water splashes

NEMA 3S

Similar to NEMA 3R, but the external controls remain operational in the presence of ice.

IP33

Protection against solid objects larger than 2.5mm, protected against water splashes at angles up to 60°

NEMA 4

Protects against dust and water splashes from all directions, including water jets, and prevents the ingress of dust or water.

IP54

Limited protection against dust, protected against water splashes.

NEMA 4X

Similar to NEMA 4, but includes corrosion protection. Used in corrosive environments (such as chemical plants).

IP55

Limited protection against dust, protected against water jets

NEMA 12

Protects against dust, oils, and non-corrosive liquids, commonly used in enclosed industrial environments.

IP65

Total protection against dust, protected against water jets.

NEMA 13

Similar to NEMA 12, but provides additional protection against the ingress of oil and coolant liquids.

IP66

Total protection against dust, protected against powerful water jets

NEMA 4

Protects against dust and powerful water jets. It is commonly used in industrial environments where robust protection is required.

IP67

Total protection against dust, temporary immersion in water

NEMA 6

Protection against water for temporary immersion, used in environments subject to temporary submersion.

IP68

Total protection against dust, continuous immersion in water

NEMA 6P

Similar to NEMA 6, but with superior protection against dust and water during prolonged immersion or in more severe conditions.

Degree of protection

As shown in the table below, the IP degree of protection is expressed by two characteristic figures depending on the behaviour of the product to which it refers according to the requirements of IEC 70-1 and IEC EN 605229.
