IEC Enclosure Accessories
nVent Hoffman IEC Global is a full line of enclosures and accessories that are internationally rated and globally available. nVent Hoffman has a patented tool-free click-in technology that allows for product versatility across wall mount and floor stand enclosures with multiple interchangeable accessories.
nVent Hoffman Standard Doors for floor standing enclosures replace the rear panel to allow access to equipment installed in the front of the enclosure. Glazed Doors are fitted with clear safety glass to view the inside of the enclosure and are equipped with a double-bit 3 mm lock system and door frame.
nVent Hoffman Separation Plates divide bayed enclosures, creating individual spaces for components to be mounted without decreasing the IP rating. Mounting Plates can be machined and equipped with components before they are fitted into the enclosure.

nVent Hoffman Universal Keyboard Trays can be mounted on any vertical enclosure surface and can be closed and locked for extra security. Drawing Desks fold away flush with the frame of a floor standing enclosure and provide a stable working surface.
nVent Hoffman Front/Rear Plinths are mounted underneath enclosures to create extra space between the floor and the bottom of the enclosure for installing cables. The space is accessible by removing the front or rear panel.
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.
