Understanding IP vs. NEMA Enclosure Ratings
NEMA Classifications NEMA 1 enclosures are typically used for protecting controls and terminations from objects and personnel. This style of enclosure, while offering a latching door, does not have a gasketed sealing surface. NEMA 1 enclosures are used in applica-tions where sealing out dust, oil, and water is . The National Electrical Manufacturer Association (NEMA) uses a standard rating system that defines the types of environments in which an electrical enclosure can be used, and frequently signifies a fixed enclosure's ability to withstand certain environmental conditions.
Enclosures protect electrical equipment from indoor and outdoor hazards, but not all enclosures offer the same level of protection. Why is this important? But, as you pull up, you see the self-order kiosk is out of order. The culprit? Rainwater managed to seep into the kiosk, causing the electrical equipment to short circuit and damage the screen. An enclosure designed and rated for these conditions could have prevented the water damage — and your rough morning. Fortunately, companies can use Nemma and IP ratings ratinh determine whether the how to obtain divorce papers they are considering offers the level of protection their application requires.
Understanding the ratings and how they compare to one another is critical for the safety ne,a functionality of your personnel what is nema 1 rating equipment. IP vs. Although they are similar, the ratings take different approaches and evaluate a different set of variables.
They follow a number system with each number corresponding to protective measures. For example:. The chart below offers more detailed descriptions of NEMA ratings.
IP ratings provide similar information in a slightly different format. Here, two numbers correspond to a particular set of enclosure protection — the first indicates a level of solid particle protection, the second a level of liquid particle protection.
Letters with specific meanings may also be applied in hema instances but are not mandatory. NEMA ratings do require such testing. So this may be a factor in deciding which rating you design and manufacture your enclosures to. An enclosure installed in a location where ice may build-up, like the self-order kiosk in our example above, may need you are what you eat poop NEMA rating instead of an IP rating.
Meeting Enclosure Ratings: Manufacturers Matter. Some examples of products that typically use these ratings include:. When deciding on using an Nfma enclosure rating, a NEMA enclosure rating or no ratingthink about how and where your product will be installed. Many kiosks are employed in various environments and need to be sure they succeed in all, or there are product variations to fit all climates. That will give you an idea of how your enclosure should be rated.
Why is this so important? A company with experience will be able to apply past scenarios to help you navigate how to use mla citation format design questions before entering the fabrication process. They can provide guidance on joining methods, finishing techniques and other processes to help you achieve your rating goals.

Protection Level. Protects against dust but is not dust-tight. Protects personnel from hazardous parts. Used indoors under normal atmospheric conditions. Similar to Type 1 but protects against light splashing; used indoors where condensation may occur.
Protects against falling dirt and windblown dust, against weather hazards such as rain, sleet, snow and ice. Can be used indoors but nemq used outdoors such as on self-service kiosks, or construction worksites.
As 3, but omits protection against windblown dust. As 3, but also operable when the enclosure is laden with ice. Offers additional corrosion protection; often used when saltwater is present. Used outdoors in places such as wastewater treatment plants, housing developments, and breweries.
Protects equipment inside the enclosure against some solid foreign objects such as falling dirt and settling airborne dust, lint, fibers, and debris. Temporarily submersible under certain conditions. Certified for use in areas with specific hazardous conditions.
Protects against the corrosive effects of liquids and gases. Meets drip and corrosion-resistance tests. For enclosures with knockouts, intended for indoor use.
Provides some protection against dust, falling dirt, and dripping non-corrosive liquids. Meets drip, dust, and rust resistance tests. Used indoors to provide protection against dust, spraying of water and non-corrosive coolants. Meets oil exclusion and rust rahing design tests.
17 rows · The National Electrical Manufacturers Association (NEMA) defines standards used in . Definition of NEMA Ratings What does NEMA 4 rated mean? In non-hazardous locations, there are several different NEMA ratings for specific enclosure "types", their applications, and the environmental conditions they are designed to protect against, when completely and properly installed. The following provides an overview of the NEMA Types. Dec 17, · Let’s begin with what a NEMA rating even is – I was surprised to find that NEMA ratings can be used on products, processes or procedures. They are basically standards that represent general practices in the industry. NEMA 1 – this is a big one for our variable frequency drives. It means ‘general purpose indoor’.
You might have come across one of our earlier articles about IP ratings. NEMA stands for National Electrical Manufacturers Association and is an organization developed to form the technical standards for the manufacturing of electrical equipment and medical imaging equipment.
NEMA works to set industry standards for safety, innovation, interoperability, environment, and market enhancement of our industry. Although the NEMA organization oversees a variety of responsibilities in the electrical manufacturing industry, they are most closely associated with the term NEMA Ratings and the type of enclosure an electrical component is built with.
This is where the similarities with IP ratings begin. IP stands for International Protection but is almost always interpreted as Ingress Protection because it is the rating system that denotes the level of protection from ingress of dust and water. The NEMA rating system, just like the IP rating system, allows us to identify an enclosure to suit the environment that it is to be installed. NEMA ratings are used exclusively for enclosures, but IP ratings can be used for all kinds of devices.
The IP rating systems use two digits, for example, IP66, where the first number indicates the level of dust protection. In this case, the 6 means the enclosure is completely protected against dust. The second number indicates the level of water ingress protection, with 6 meaning the enclosure is protected against heavy water jet spray. Type 1 NEMA rated enclosures are constructed for indoor use to provide a degree of protection against access to hazardous parts and to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects, for example, falling dirt.
Type 2 NEMA rated enclosures offer the same level of protection as a Type 1, but with added protection to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water, for example, dripping or light splashing. This is now where things get a bit different.
Type 3 NEMA ratings are broken down into 3 protection levels, with a corrosive protection option, so 6 in total. Type 3R and 3RX NEMA rated enclosures are engineered for indoor or outdoor use and protect against rain, sleet, snow, dirt, and prevents the formation of ice on its enclosure, with the 3RX adding protection against corrosion.
Type 3 and 3X NEMA rated enclosures are rain-tight, sleet-tight, and dust-tight and are made for both indoor and outdoor use. Type 3S and 3SX NEMA rated enclosures benefit from the same protection as a NEMA 3, however, provides protection when ice forms on the enclosure and will remain operable when covered in ice, again with the 3SX adding protection against corrosion.
It can handle light splashing, but cannot be submerged for periods of time. Type 11 NEMA enclosures are corrosion resistant and offer protection whilst submerged in oil. They are intended for use indoors to protect the equipment against dripping of corrosive liquids. Type 11 also protects against the corrosive effects of fumes and gases by providing immersion protection of the equipment in oil.
A type 12 does not include knockouts, which are partially punched openings that can be removed to accommodate cables, connectors or conduits, whereas a Type 12K does. Type 7 NEMA enclosures are built for hazardous locations, so the enclosure is explosion-proof and made for indoor use.
Type 9 NEMA enclosures are dust ignition proof and intended for indoor use in hazardous locations. National Electrical Manufacturers Association, or NEMA, is an organization that deals with technical standards for the manufacturing of electrical equipment and medical imaging equipment.
Most commonly, they are known for their rating system, known as NEMA Rating which classifies the level of protection an enclosure has against environmental elements.
They are closely related to IP Ratings, but they allow for additional environmental elements such as corrosion. NEMA ratings are used exclusively for enclosures, but IP ratings can be used for all kind of devices. Now you should have a greater understanding of what the NEMA enclosure rating system is used for, and how we are able to select the right type of enclosure to give us the required protection level of our system.
