    Your devices are only as good as their protection.

    So you have your circuit breaker, your panelboard, your switchgear… Now it’s time to protect them all. Enclosures are designed to withstand environments of all types in order to protect your distribution devices from damage and protect operators during maintenance. Enclosures can be built of various materials including steel, stainless steel, fiberglass, PVC, polycarbonate and more. If you’re installing your enclosure outdoors, a stainless enclosure or metal enclosure would be best, while fiberglass electrical enclosures and polycarbonate enclosures are best for indoor use.

    What you need to know about NEMA ratings.

    NEMA is a regulatory body that outlines the standards for a different types of enclosures. NEMA ratings for enclosures are ranked from NEMA 1 to NEMA 13. Each NEMA rating indicates what kind of conditions the enclosure itself is able to withstand. For example, NEMA 1 electrical enclosures and type 2 enclosures are general duty indoor enclosures that protect against dirt and some moisture (type 2), while NEMA 3 and NEMA 3R electrical enclosures are used outdoors to protect against falling rain, sleet, snow, and ice. NEMA 4X electrical enclosures are used outdoors to protect against rain, sleet, snow, and ice, as well as splashing and water that is directed at it. Other NEMA enclosures can protect against corrosive materials, fibers, solid foreign objects and more. All NEMA enclosures that are rated for outdoor use can be used indoors as well, but not vice versa.

    Steel (Metal) Cabinets/Enclosures

    Steel (Metal) Cabinets/Enclosures

    While not corrosion resistant, Steel enclosures are effective in protecting your devices from dust and water. A solid indoor enclosure, steel enclosures are used in the commercial sector for light or medium duty protection.

    Stainless Steel Enclosures

    Stainless steel electrical cabinets can be used both indoors and outdoors. They are either composed of type 304 stainless steel or type 316 stainless steel. As a corrosion resistant enclosure, they are a versatile enclosure used in a number of applications, both industrial and commercial.

    Non-Metal, Plastic/PVC, Fiberglass Enclosure

    Non-Metal, Plastic/PVC, Fiberglass Enclosure

    Fiberglass electrical enclosures, plastic enclosures and polycarbonate enclosures are extremely cost-efficient and highly durable. They are not ideal for outdoor use since they can weaken with prolonged outdoor exposure, but they are popular for indoor use as they are corrosion resistant while remaining aesthetically pleasing.

    Free-Standing Enclosures

    Similar to modular enclosures, free standing enclosures do not rely on a wall for support and can be installed wherever there is available floor space. Free standing enclosures are commonly used for heavy industrial applications from food processing to data processing, either indoors or outdoors.

    Modular Enclosures

    Commonly used as a space-saving solution in an indoor setting, modular enclosures can be moved around and to better optimize the space. Modular enclosures come with many mounting provision options to suit your space. They are commonly found in the telecommunications industry.

    Wall-Mount Enclosures

    Wall mount enclosures are used when the floor space isn’t available. They help maximize your floor space while giving you easy access to equipment controls and other devices. Applications that rely on wall mount enclosures include construction and any sector that requires machine control.

    Panel Enclosures

    Panel enclosures are available with single doors, double doors, lift off covers and hinge covers. Used to protect your panel either indoors or outdoors, panel enclosures can be constructed of stainless steel, steel or other non metallic materials.

    Custom Enclosures

    Custom Enclosures

    When a standard sized enclosure just won’t cut it, a custom enclosure is a great option. A custom enclosure allows you to choose door configurations, mounting provisions, a choice of windows or vents, padlock options, drip shields, door stays, and more.

    Circuit Breaker Enclosures

    Circuit Breaker Enclosures

    Used to protect your circuit protectors, circuit breaker enclosures are available in all sizes. Most circuit breaker enclosures are constructed of stainless steel. They also protect operators and maintenance workers from accidentally touching energized components.

    Outdoor / Weatherproof (NEMA 3R) Enclosures

    Outdoor / Weatherproof (NEMA 3R) Enclosures

    The most common outdoor enclosures and weatherproof enclosures are NEMA 3R rated and NEMA 4X rated, though many others are available. Outdoor enclosures are built to withstand rain, sleet, snow, and even ice build up on the outside of the enclosure. Outdoor enclosures can also include padlock provisions to prevent theft.
