What are NEMA Enclosure Types?

NEMA is a classification scheme for devices that can be subjected to liquids, rain, frost, rust, and foreign matter such as soil.

If you are unsure of the enclosure ranking that your project needs, please consult the construction map below. The map will assist in determining the required enclosure rating for the setting and application.

What is Defined as an Enclosure?

An electrical enclosure is a cabinet or box that protects electrical or electronic equipment and prevents electrical shock. Enclosures are usually made from rigid plastics or such metals as steel, stainless steel, or aluminum. Enclosures are rated to designate protection against hazardous, non-hazardous, and other specific environmental conditions.

How can Megalab Lab Help?

We have the capability to evaluate your product for dust and water resistance according to the NEMA 250, UL 50E and CSAC22.2 No. 94.2 standards for ingress protection. To achieve compliance to common standards or NEMA classifications, products must demonstrate an acceptable level of ingress protection. IP ratings are also often required by sellers or retailers before a product is purchased from manufacturers and resold to consumers, regardless of a product’s intent to protect against dust or water.
