Types, Features, and Advantages of General Purpose Enclosures

Listed below are some types of general-purpose enclosures. This article will discuss Type 12 gasket enclosures and Type 1 surface-mounted or flush-mounted enclosures. The enclosures also have options to accommodate different mounting systems. Please visit the manufacturer's website for a more comprehensive range of general-purpose enclosures and  also discuss the advantages and disadvantages of each.

Type 12 gasket enclosures:

Before choosing a general purpose enclosure, it is important to determine which NEMA rating it requires. Type 12 enclosures are rated for indoor use, while Type 13 is rated for outdoor use. The NEMA 3 series enclosures are rated for basic weather hazards. A NEMA 3S is rated for protection from ice and snow. The NEMA 4 is rated for indoor and outdoor use and is watertight. It can withstand water and hose-directed water. In addition, the NEMA 4 enclosure is corrosive-resistant, making it perfect for both indoor and outdoor applications.

A Type 12 gasket general purpose enclosure is a metal box that protects against falling dirt, fibres, and airborne dust. It also prevents moisture and dripping water from getting inside. The materials used in NEMA 12 enclosures make them medium-cost products. Many of them feature a protective powder coating and a foam gasket. A drip shield is also a recommended feature. These general purpose enclosures are available in various sizes and shapes.

Similarly, Type 12 enclosures comply with NEMA standards for protection against corrosion and oil leakage. However, NEMA ratings provide better protection against common industrial hazards. While IP54 is the most widely used in the United States, IP65 enclosures are more rugged and dust-tight than NEMA type 12.

Materials for Type 12 enclosures:

NEMA Type 12 enclosures are also available in various materials. Each material has unique features and performance specs that make them perfect for various applications. The polycarbonate enclosure, for example, is durable and offers a high level of protection against UV rays. ABS plastic enclosures are a cheaper alternative but still durable and attractive. Aluminium enclosures are widely used and provide natural RFI shielding.

NEMA 6p enclosures are usually made of stainless steel or plastic. They are rated NEMA 4X and NEMA 6P and are used for applications where more protection is necessary. They are ideal choices in harsh environments. Examples of these applications include petrochemical, marine, and offshore oil platforms. They are available in various sizes and configurations. You can choose a single-door floor-mount enclosure to meet your needs.

Applications of Type 12 enclosures:

NEMA-rated Type 12 enclosures are generally used for indoor and outdoor applications. They are available in a single or double door design. They are finished with an ANSI 61 grey polyester powder coating and feature removable and concealed hinges. A standard plastic self-adhesive print pocket is also available on Type 12 enclosures. If you have a unique requirement, you can consult with an expert.

NEMA control panel enclosures are typically used for control panel components, such as membrane switch panels and alarms. A Type 12 enclosure can protect against accidental contact with the electronics inside. A Type 12 enclosure is also used to protect against falling dirt and dust. These enclosures are also used in solar power systems. Commercial NEMA enclosures are commonly used in theatres and stadiums where electrical power and HVAC systems are needed.

When choosing a gasket for a type 12 enclosure, it is important to consider the function of the enclosure. The gaskets must resist water pressures and flow rates. The material must also resist mechanical wear and exposure to UV or ozone. Exposure to pooled water during rain showers can affect gasket durability. In addition, cool rain on a hot box can create a vacuum effect.

Type 1 Surface or Flush Mounted Enclosures:

The HOFFMAN HOFASE10X10X6NK is a surface-mounted general purpose enclosure that blocks public access to lighting controls. The enclosure is available in four standard heights: fourteen inches, twenty-one inches, and thirty-eight inches. It is designed for surface mounting and features numerous cable entry knockouts and a vertical mounting hole pattern. It also has four Torx-head mounting screws for securing the door.

The NEMA Standard lays down the characteristics of products. The NEMA 1 enclosures are made to protect against various contaminants, including hazardous parts, solid foreign objects, and water. The enclosures are sealed against oil, non-pressurized water, and airborne dust. They are available in aluminum, carbon steel, and stainless steel. The NEMA standards are followed when manufacturing these enclosures.
