Standard enclosures may not provide adequate protection in industrial settings, where electrical equipment is exposed to harsh conditions such as moisture and physical impacts. Custom electrical enclosures address this challenge by offering enhanced durability and protection against environmental factors. They are tailored to specific requirements, offering a range of sizes, configurations, and features to meet the unique needs of different applications.

The National Electrical Manufacturers Association (NEMA) sets the standards for these enclosures, ensuring they meet specific requirements for different applications. In this blog, we will explore the NEMA standards 4, 4X, and 6P and their key benefits and applications.

NEMA 4 Enclosures

NEMA 4 enclosures are constructed using rugged, corrosion-resistant materials such as stainless steel or fiberglass, providing durability and reliability in harsh environments. They are designed to protect electrical components from falling dirt, dust, and water splashes. These electrical housings can also withstand various temperatures, ensuring that parts remain safe and operational in multiple weather conditions.

Custom enclosures built to NEMA 4 standards are often used in industrial settings, wastewater treatment plants, and outdoor installations. To meet specific application requirements, they can be customized with various sizes, mounting options, and additional features, such as viewing windows or ventilation systems.

NEMA 4X Enclosures

NEMA 4X enclosures provide additional corrosion resistance over NEMA 4 housings. They are typically made from durable materials like stainless steel or polycarbonate, which are ideal in applications exposed to corrosive substances such as saltwater or chemicals. Thus, they are often used in food processing plants, wastewater treatment facilities, and outdoor installations.

Custom NEMA 4X enclosures can be tailored with features like sloped roofs, rain hoods, and drainage systems. These ensure that water and debris do not accumulate on the enclosure’s surface. They can also be equipped with gaskets and seals to provide a watertight seal.

NEMA 6P Enclosures

NEMA 6P enclosures are designed to provide the highest level of protection against water and dust ingress. Similar to NEMA 4X housings, they are often made with stainless steel or polycarbonate and designed to endure prolonged submersion in water up to a specified depth.

Custom NEMA 6P enclosures can be used in underwater sensors, marine equipment, and wastewater facilities where protection against water ingress is critical. They can be customized with features like pressure relief valves, cable glands, and underwater connectors to ensure reliable operation in underwater environments.
