nVent HOFFMAN is a leading manufacturer of high-performance electrical enclosure systems for demanding indoor and outdoor applications. From basic environmental protection to hazardous or corrosive applications, our UL-, IP-, and NEMA-rated electrical enclosure solutions have you covered.
Benefits of APO Enclosure Systems
An enclosure is a cabinet for electrical or electronic equipment to mount circuits, switches, knobs, and displays. Occasionally called a housing or box, it prevents electrical shock to equipment users and protects contents from the environment. Additional advantages of the APO NEMA 4X enclosure with fiberglass cover includes:
- Flame retardant, self-extinguishing
- Protects against water, oils, coolants, dirt, and dust
- Prevents incidental contact with internal equipment
- Keeps the enclosed equipment in good and functioning condition
APO NEMA modular fiberglass electrical enclosures from nVent HOFFMAN are designed for use as insulated electrical junction boxes, terminal wiring boxes, instrument housings, and electrical control enclosures in highly corrosive environments.

Applications for APO Enclosure
All APO series enclosure systems have a 4X rating from NEMA, or the National Electrical Manufacturers Association. A NEMA 4X rating means the enclosure has been rigorously tested to ensure optimum performance in outdoor use and offers a superior level of protection against corrosion and extreme conditions. A NEMA 4X rating makes nVent HOFFMAN APO series enclosures with fiberglass covers perfect for a variety of applications.
- Indoor or outdoor use
- Offshore operations
- Protection against windblown dust and rain
- Hygienic environments
- Protection from splashing water and hose-directed water
- Hazardous conditions
Bases and opaque covers are made from hot compression-molded halogen-free, self-extinguishing fiberglass-reinforced polyester, or FRP. Its characteristics include smooth internal surfaces, heightened thermal insulation capabilities, high-temperature resistance, and robust anti-corrosion properties in a lightweight, high-strength package. FRP can withstand continuous temperatures up to 302F degrees Fahrenheit, or 70 degrees Celsius, and momentary exposure to degrees Fahrenheit, or 150 degrees Celsius.
Client-Tailored Electrical Enclosure System Solutions
If you regularly buy standard electrical enclosures and boxes, you know many options are available. However, standard or off-the-shelf products aren’t always best. nVent HOFFMAN offers an array of services tailored to help clients obtain the right electrical enclosure system for their application.
Another common modification is special paints and finishes, which can be beneficial for branding purposes. Standard enclosures tend to be basic gray colors that blend into their surroundings and go unnoticed. Imprint & Paint Shop services give the option for special colors, logo identification, and labeling, and provide limitless options for a unique appearance.
