Hoffman Modular Enclosure Frames & Racks

filter_list

Frames and Racks consists of metal forms with with pre-drilled holes that are spaced at standardized units of measurement that will accommodate common accessories that can be added to the interior or exterior without drilling or welding. Modular frames can be joined to one another, creating the possibility of multiple configurations, and rails can be added to the frame making it possible to slide panels into and out of the enclosure from the front, rear or side openings. 

Hoffman PROLINE G2 frames protect components inside this line of modular enclosures. The frames were designed to withstand heavier load requirements and to provide a solid foundation for the electrical enclosure.

Hoffman PROLINE G2 disconnect frames can be used with PROLINE G2 disconnect doors and components to configure a custom disconnect enclosure from standard enclosure components.

Hoffman PROLINE G2 heavy-duty swing-out rack frame allows 19 inch rack panels or equipment to pivot for better accessibility. The center pivot provides a 350 degree rotation with a 400 pound load rating. Right or left offset options allow the frame to pivot out of the enclosure and are capable of 140 degree rotation.

Hoffman PROLINE G2 full access rack is a design adaptation of the heavy-duty swing-out rack frame, serving a similar function, but allows the rack frame to swing out of the enclosure for full access to the 19 inch rack equipment. The full access rack has been rated to a 300 pound load capacity.

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.
