A housing for electrical or electronic equipment is known as an electrical enclosure. Its goal is to protect the equipment from the environment (particularly in the case of outdoor electrical enclosures) as well as from people (e.g. to prevent electric shock or the propagation of an explosion).

Electrical enclosures may appear unimportant at first look. However, in industries such as telecommunications, IT systems, utilities, and the Internet of Things (IoT), among others, these meticulously constructed boxes play a critical role in protecting electronics. electrical enclosures are more crucial than ever as our technology advances at a breakneck speed.

Mongolia’s power grid accounts for 3% of GDP and provides electricity to 80% of the country’s population. The system is regarded as an important branch of Mongolia’s economy and infrastructure sector, and it has a significant impact on the country’s social and economic viability.

We’ll go over the most common types and functions of electrical enclosures in Mongolia’s tech industry in this piece.

What Is an Electric Enclosure

Enclosure Boxes

An electrical enclosure is a container for electrical or electronic equipment that is used to place switches, knobs, and displays, as well as to protect the contents from the environment and to prevent electrical shock to users. Users can only view the enclosure because it is the only portion of the device they can see. It could be created not merely to meet functional needs, but also to be attractive to the sight. 

Enclosures for electrical equipment in hazardous places, such as petrochemical factories or coal mines, may be required to meet certain specifications. Heat dissipation, radio frequency interference, and electrostatic discharge protection may all be demands placed on an enclosure by electronic packaging.

The most common materials used in electrical enclosures are hard plastics or metals such as steel, stainless steel, or aluminum. Cabinets made of steel might be coated or galvanized. Enclosures for mass-produced equipment are usually customized, however for custom-built or small production runs of equipment, standardized enclosures are used. ABS is utilized in plastic enclosures for interior applications only, not in hostile conditions. Where tougher cabinets are necessary, polycarbonate, glass-reinforced, and fiberglass boxes are utilized, with a gasket to keep dust and moisture out.

Types Of Electrical Enclosures In Mongolia

Most people refer to the enclosure types defined by the National Electrical Manufacturers Association when discussing the various “types” of electrical enclosures (NEMA). The North American Electrical Enclosures Manufacturers Association (NEMA) is the group that sets the standards for electrical enclosures in North America. Most manufacturers in the United States design their enclosures to increase the safety and reliability of their goods. The most common NEMA-rated electrical enclosures in Mongolia are discussed below, as well as the vital role they play in ensuring product function and safety.

NEMA Type 1

NEMA Type 1 enclosures are intended for use indoors and provide the least amount of protection of any NEMA-rated enclosure. Light dust, filth, and inadvertent contact with electrical equipment are all protected by these enclosures.

NEMA 1 enclosures are commonly used in a variety of industries to house indoor electrical equipment, such as variable-frequency drives put in conventional interior locations, despite their poor protection.

NEMA 3 enclosures can be used both indoors and outside. They are, however, mostly employed as electrical enclosures for outdoor use. This is because NEMA 3 enclosures protect against falling dirt, rain, snow, sleet, and the formation of exterior ice. These enclosures can be used as outdoor electrical junction boxes to protect wire and equipment, albeit they may not be suited for extreme weather.

NEMA Type 4

When compared to NEMA 3R enclosures, NEMA 4 enclosures provide more protection against adverse weather conditions. Most importantly, they are watertight, making them ideal for industrial applications such as protecting outdoor wiring systems, power systems, and telecommunications equipment that is mounted.

There is a substantial difference between a NEMA 3R weatherproof enclosure and a NEMA 4 waterproof enclosure. NEMA Type 4 enclosures, unlike Type 3 and 3R, provide some protection against splashing and hose-directed water.

The protective seal on the enclosure is another significant variation between the two types. A NEMA 4 enclosure’s gaskets maintain a watertight seal, preventing water infiltration.

NEMA 6 enclosures are utilized in applications where temporary submersion in water is a possibility. They are designed for both indoor and outdoor use. Waterproof electrical boxes are used in a variety of applications, including electric vehicles and maritime transportation.

Design engineers have little to worry about when using a NEMA 6 enclosure. NEMA 6 enclosures defend against damp conditions, falling debris, exterior ice formation, and water penetration while temporarily immersed, in addition to protecting accidental contact with electrical equipment.

Purpose Of NEMA Ratings

The ability of an electrical enclosure to tolerate specified environments and hazards is determined by its NEMA rating. Engineers will be able to select an electrical enclosure with greater confidence in its capacity to perform as a result of this.

A utility firm storing sensitive electrical equipment outdoors in a coastal area, for example, would choose a NEMA 4X enclosure to guard against the elements and salt spray corrosion.


With the advancement of technology, we are beginning to deploy electrical equipment in several atypical locations. Choosing a suitable electrical enclosure for the application at hand is crucial for ensuring the proper protection of electrical components.

Eabel has a wide range of enclosures that may be customized to meet the needs of almost any application. We have enclosures for both indoor and outdoor environments, ranging from waterproof polycarbonate plastic enclosures to diecast aluminum enclosures with NEMA 4X standards.
