| First Number | Degree of Protection | Second Number | Degree of Protection |
|---|---|---|---|
| 0 | No Protection | 0 | No Protection |
| 1 | Protected against solid foreign objects of 50 mm diameter and greater. | 1 | Dripping water ( vertically falling drops) shall have no harmful effect. |
| 2 | Protected against solid foreign objects of 12.5 mm diameter and greater. | 2 | Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position. |
| 3 | Protected against solid foreign objects of 2.5 mm diameter and greater. | 3 | Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect. |
| 4 | Protected against solid foreign objects of 1.0 mm diameter and greater. | 4 | Water splashing against the enclosure from any direction shall have no harmful effect. |
| 5 | Ingress of dust is not entrely prevented, but it must not enter in sufficient quantity to interfere whth the satisfactory operation of the equipment. | 5 | Water projected by a nozzle against enclosure from any direction shall have no harmful effects. |

What is IP Code?
IP is short for International Protection (or Ingress Protection), which classified dust and water tight degree for enclosures.
When dust and water enters the enclosure, electrical devices might deteriorate or malfunction.
Save maintenance cost with Non-stone IP rated enclosures by preventing dust and water effectively.
Different degrees of IP rating
IP55 stands for dust tight 5 and water tight 5.
Dust tight degree: Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.
Water tight degree: Water projected by a nozzle against enclosure from any direction shall have no harmful effects.
An IP 55 enclosure is suitable for general indoor environment.

IP66 stands for dust tight 6 and water tight 6.
Dust tight degree: No ingress of dust.
Water tight degree: Water projected in powerful jets against enclosure from any direction shall have no harmful effects.
An IP 66 enclosure is suitable for general outdoor environment.

IP67 stands for dust tight 6 and water tight 7.
Dust tight degree: No ingress of dust.
Water tight degree: Short periods of immersion in water shall have no harmful effects.
IP69K stands for dust tight 6 and water tight 9K.
Dust tight degree: No ingress of dust.
Water tight degree: Close-range high pressure, high temperature water jets should have no harmful effects.
NEMA Non-Hazardous Location Enclosure Standard
美國電氣製造商協會 (National Electrical Manufacturers Association，簡稱NEMA) 創立於1926年，總部設於美國華盛頓近郊，主要任務為發展與發行推廣工業用技術標準。根據該協會統計，目前會員約有450家，相關產品產值約1200億美金。
NEMA4 NEMA TYPE 4
Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and windblown dust); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow, splashing water, and hose directed water); and that will be undamaged by the external formation of ice on the enclosure.
NEMA4X NEMA TYPE 4X
Enclosure constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (windblown dust); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow, splashing water, and hose directed water); that provides an additional level of protection against corrosion; and that will be undamaged by the external formation of ice on the enclosure.
NEMA 12 NEMA TYPE 12
Enclosure constructed (without knockouts) for indoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and circulating dust, lint, fibers, and flyings); and to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (dripping and light splashing).
