What is the difference between metal enclosure and metal-clad?

Metal enclosures and metal-clad enclosures are two common types of enclosures used to house electrical components. While they may seem similar, there are actually some key differences between the two.

Metal enclosures are typically made entirely of metal, such as steel or aluminum. These enclosures are often used in industrial environments where durability and protection are top priorities. Metal enclosures provide excellent shielding against electromagnetic interference and are also highly resistant to physical damage, making them a popular choice for housing sensitive electrical equipment.

On the other hand, metal-clad enclosures are a bit different. These enclosures are also made of metal, but they have a protective layer of insulation, such as plastic or rubber, on the inside. This insulation helps to prevent electrical components from coming into direct contact with the metal enclosure, reducing the risk of short circuits and electrical shocks. Metal-clad enclosures are commonly used in residential and commercial buildings where safety is a major concern.

In terms of cost, metal enclosures are usually more expensive than metal-clad enclosures due to the additional materials and labor required to manufacture them. However, the extra cost is often justified by the superior protection and durability that metal enclosures provide.

In summary, the main difference between metal enclosures and metal-clad enclosures lies in the level of insulation they offer. Metal enclosures are solid metal boxes that provide excellent shielding and protection, while metal-clad enclosures have an additional layer of insulation to prevent electrical hazards. When choosing between the two, it's important to consider the specific needs of your application and select the enclosure that best meets those requirements.
