Industry Information

NEMA Enclosures

NEMA enclosures offer a number of advantages for a variety of applications. NEMA stands for National Electrical Manufacturers Associations, which means that each NEMA enclosure is designed to meet strict standards for use in a variety of electrical applications that are commonly used in industrial settings. There are a range of grades for each design as they are built to meet specific application requirements. One grade may be perfect for a certain application but it won't have the right properties for a different application. There are around 20 different grades of NEMA enclosures to choose from, so it is important to work with an experienced NEMA enclosure manufacturer in order to receive the right enclosure based on your application and requirements.

As stated before there are a number of different advantages that these designs and standards offer and each different grade of NEMA enclosure provides different properties such as drip-tight designs, water tight construction, heat resistance, and protection from dust, light, and environmental hazards as well as many, many other properties. Many of these enclosures are made from polycarbonate which provides a number of advantages itself as it has high impact strength, can withstand extreme temperatures and can be easily customized to fit a specific application. The grades range from 1 to 12 with a few variations thrown in between. For example, there are six different grade 3's: 3, 3R, 3S, 3X, 3RX, and 3SX. The X refers to the enclosures as being corrosion resistant and the other additional letter each represent certain properties or the omission of properties from the standard grade.

The diversity of NEMA enclosures is the reason why knowing your application and needs is so crucial to receiving the right NEMA enclosure for your specific application. Whether you are seeking a NEMA enclosure that is designed to protect against dust, water, coolant, oil or some other outside hazard, finding the right enclosure is vital to ensuring that your enclosure functions properly and most effectively. Another important step to receiving the best possible NEMA enclosure for your application is to work with a trusted, experienced NEMA enclosure manufacturer, one who has the knowledge and capability to manufacturer and suggest the right grade of NEMA enclosure for your application.

NEMA Ratings for Electronic Enclosures Explained

In today's modern society, humans cannot sustain a normal life balance without the use of electricity and electrical components. Electrical wires and components are enclosed cabinets, which are manufactured in compliance with governmental standards. These electrical enclosures ensure the faultless operation of electrical components, protect parts from their environment, and prevent complications that usually arise due to electromagnetic interference.

The National Electrical Manufacturers Association (NEMA) is an organization that has laid out standards regarding manufacturing of electronic enclosures and categorized different types of enclosures for different needs. However, a NEMA rating, given the different types and categories of electronic enclosures, sometimes causes confusion among electrical component buyers. Therefore, the following paragraphs describe several considerations you need to know about NEMA ratings.

NEMA Organizational Objectives

For helping manufacturers determine the proper function, safety, and compatibility of electrical and electronic components, NEMA issues technical papers, standards and guides. There is a common notion that NEMA is an agency that tests products and certifies products. However, the organization only defines standards, and a manufacturer can decide voluntarily to comply with those standards. Nonetheless, NEMA ratings are relevant in quality manufacturing and are followed and applied widely.

How does NEMA categorize electronic enclosures?

NEMA standard industrial control and systems (ICS) primarily classify electrical enclosures based on the location of installation, whether the location is hazardous or non-hazardous. Furthermore, NEMA classifies electronic enclosures based on their ability to withstand damage due to corrosive compounds, liquid and dust, and their capability to guard against ingress.

The NEMA enclosure classification for non-hazardous locations includes eight major types and subtypes:

  • Type 1 and Type 2 are similar and are meant for indoor use and provide protection against ingress and human contact. However, Type 2 is drip-proof.
  • All subtypes of 3, 3R, 3 X, 3RX, 3S, and 3SX, are corrosion-resistant, provide protection from rain and snow, and can be installed indoors or outdoors. Among them, 3RX type is manufactured to be resistant against wind. And 3S and 3SX have external auxiliary equipment fitted to make them operable even when ice is present. Wherever "X" is added, it means the enclosure is corrosion resistant.
  • Types 4, 4X are the same as Type 3 but also add protection in terms of splashing and hose-directed water resistance.
  • Type 5 is manufactured for indoor use and is the same as Type 2, but includes gaskets which the prevent ingress of lint, fibers, and dust.
  • Type 6 and 6S have aspects similar to type 4, however, they provide protection against submersion. Type 6 can be submerged temporarily and still provide protection, whereas 6 S can sustain prolonged submerged until limited depth.
  • Type 12 and 13 are almost the same. Types 12 are meant for indoors and provide protection against all indoor interferences, including dripping and splashing water. Type 13 also provides protection from oil and coolants.

NEMA enclosures for hazardous locations include Type 7 to 10.

  • Type 7 is only indoor use and explosion proof, whereas type 8 can be installed outdoors.
  • Type 9 provides protection against ignition and is used indoors.
  • Type 10 can be made so robust that they can withstand nearly any environment.
