nVent Hoffman Aluminum Enclosures
nVent Hoffman aluminum enclosures are a line of protective enclosures made from aluminum that are designed to protect electrical and electronic equipment from environmental factors such as dust, dirt, moisture, and corrosive materials. These enclosures are manufactured by nVent Hoffman, a brand of Pentair, a leading manufacturer of electrical and electronic equipment protection products.
The aluminum construction of nVent Hoffman enclosures offers several advantages over other enclosure materials, including high strength-to-weight ratio, corrosion resistance, and thermal conductivity. These properties make aluminum enclosures ideal for use in harsh environments where protection against corrosion and extreme temperatures is necessary.
nVent Hoffman aluminum enclosures are used in a variety of industries, including automation and control, telecommunications, energy, and transportation. They are commonly used to protect electrical and electronic components such as control panels, PLCs, switches, and routers.

nVent Hoffman COMLINE Aluminum Enclosures
nVent Hoffman ComLine aluminum wall-mount enclosures provide long-lasting protection for housing electrical components in extreme outdoor environments. These lightweight, corrosion-resistant enclosures have a foam-in-place gasket for a tight seal and are ideal for rooftop or tower-mounted telecommunications applications.
nVent Hoffman COMPACT Aluminum Enclosures
nVent Hoffman COMPACT aluminum enclosure with a NEMA rating of 4x are for use in outdoor or indoor applications and protect components and controls in corrosive environments, such as marine environments. Stainless steel captivated cover screws are placed outside the sealed area and an oil-resistant, seamless foam-in-place gasket helps prevent liquids from penetrating the enclosure. Threaded internal bosses are provided for mounting optional panels, rails and other components. Mounting holes are provided in corners outside of the gasketed area. Mounting hardware is included.
NEMA 3R, 4, 4X Enclosures
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 3R Enclosures
The NEMA definition of a 3R enclosure is as follows: ‘Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts, to provide a degree of protection of the equipment inside the enclosure against Ingress of solid foreign objects such as falling dirt, to provide a degree of protection with respect to harmful effects on the equipment due to the Ingress of water, rain, sleet or snow, and that will be undamaged by the external formation of ice on the enclosure.' NEMA 3R enclosures provide adequate outdoor protection while providing significant cost savings over NEMA 4 and NEMA 4X enclosures.
NEMA 4 Enclosures
They provide all of the same protections found in the NEMA 3R enclosures with two additional protection elements, protection against wind-blown dust particles and protection against hose directed water. NEMA 4 enclosures provide this additional protection using a gasket material to prevent water or dust from entering the enclosure, while the NEMA 3R enclosures rely on enclosure design and gravity to assist in diverting water and dust.
NEMA 4X Enclosures
They provide all of the same protections found in the NEMA 4 enclosures with one added protection element, corrosion resistance. NEMA 4X enclosures are typically made of either stainless steel or fiberglass.
