NEMA 4 Enclosure

Keeping moisture away from electrical and electronic components is essential for a safe working environment. Protecting employees from electrical shocks and potential fire hazards is important for regulatory compliance in many industries.

Water, oil, chemicals, dirt, and dust are also bad for electrical components and electronics, from transformers and actuators to PLCs and circuit boards. Short circuits can cause permanent damage to equipment, while accumulated dirt can lead to interrupted signals, premature wear, and malfunctions. A water-resistant NEMA enclosure can help you keep operations running smoothly and avoid costly stoppages or equipment breakdowns.

If your enclosure is to be used in a corrosive environment, you need to upgrade to a NEMA 4X enclosure. We can help you choose between aluminum or 316 stainless steel for your application environment and specifications.

NEMA 4 enclosures are generally gasketed with doors that clamp to provide a maximum seal. They can also be equipped with continuous hinges, mounting feet, and padlock hasps.

NEMA 4 enclosures stand out because of their watertight protection against splashing water and indoor washdowns from commercial hoses. They also offer ingress protection from windblown dust, dirt, debris, rain, sleet, snow, and ice.

Whereas NEMA 3 enclosures offer general-purpose weather protection in outdoor spaces, NEMA 4 electrical enclosures offer maximum protection against moisture and dust in outdoor environments. NEMA 4 water-tight enclosures have an outstanding IP66 rating, making them ideal for harsh climates, coastal environments, and other demanding locations.
