NEMA separates enclosures into different classes by their ability to provide protection against solid objects, corrosive liquid, noncorrosive liquid, and corrosion.

Nemaco offers 6 classes of NEMA enclosures adherence to NEMA Standard Publication 250-2003: NEMA 3R, 4, 4X, 6, 6P and 12. For more information regarding NEMA ratings, please visit our NEMA rating standard resources. If you are already familiar with NEMA ratings, please visit our NEMA enclosure products page.


Additionally, we offer enclosures that adhere to Ingress Protection (IP) or International Protection ratings. These ratings are defined by the international standard of EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). These IP codes are used to outline levels of protection for the application inside enclosures against solid and liquid.

IP ratings are indicated by two digits, each with its own meaning, i.e.:

  • IP65 ( number 0 – 6 or letter X )
    The first digit in the combination refers to the level of protection that the enclosure provides against access to internal hazards(e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.
  • IP66 ( number 0-9 or letter X )
  • The second digit in the combination refers to the level of protection that the enclosure provides against harmful ingress of water.

If you are already familiar with IP ratings, please visit our Nemaco IP enclosure products. However, if you need more information about IP ratings, please visit our resources.

Please be advised, IP ratings and NEMA ratings are the two industry standards. Both use different methods to categorize levels of protection  enclosures provide. Therefore, please ensure you understand all details about both standards to clearly specify which Nemaco enclosure suits your needs.
