Modular Enclosures

More Information about Modular Enclosures

When assembly and maintenance have been simplified to the point of ease, then there is no question as to what direction to proceed with the installation. For this reason, we can talk about modern enclosures that are "modular," meaning that the units are relatively small and easily brought together to form something large. These modular enclosures are not only ideal for working on test and computing equipment at home but also bylaws-compliant, as they can integrate into every residential or commercial environment found (i.e., indoors or outdoors).

FAQs

What features and accessories can be added to modular enclosures that make access easier?

Modular enclosures can be equipped with features and accessories like removable panels, hinged doors, sliding trays, cable entry systems, and ergonomic handles to enhance access and simplify maintenance.

Do modular frames come with removable sides?

Yes, modular frames often come with removable sides to allow flexible access and easy customization for various applications.

Enclosure Selection Basics

Electrical enclosures are cabinets that are designed to house electrical components. Their main function is to protect the components, as well as to protect the operators from electrical hazards. Enclosures are typically made of solid plastics, fiberglass and metal materials, such as carbon steel, stainless steel and aluminum.

One of the most important things to consider when selecting an electrical enclosure is the NEMA rating. NEMA stands for National Electrical Manufacturer Association. They have developed a rating system which determines the types of environments an electrical enclosure can be used in. 

NEMA 1 and a NEMA 12 enclosures

Both of these enclosures are intended for indoor use only. They are both dust resistant. The NEMA 12 enclosure is rated for damp environments. The NEMA 1 is rated only for dry environments.  

NEMA 4 and NEMA 4X enclosures

Both of these enclosures can be used indoors as well as outdoors. They are both dust resistant. They are also water resistant and corrosion resistant. NEMA 4X has an extra layer of corrosion resistance.

NEMA 7 enclosures

This is a more specific type of enclosure that is rated for use in hazardous environments. It is rated to contain an explosion within the enclosure and not cause any sort of external hazard. 

Size

When selecting the size of an enclosure, it is important to consider the following: how much space will the electrical components occupy, how much space is needed around each component, is there enough room to run all of the wires and how much space is needed outside of the enclosure?

Temperature

When selecting an enclosure, it is important to consider both the ambient temperature and the temperature that is generated inside of the enclosure. When an enclosure is located outside in direct sunlight, that heat can be transferred inside the enclosure. Also, each component inside of the enclosure generates a certain amount of heat.
