NEMA Type 4 Enclosures – Indoor Safeguard


Working in an industrial setting often means working in a demanding, potentially dangerous work environment and that requires companies to comply with high standards for safety and proper procedures. Similarly, the National Electrical Manufacturers Association (NEMA) sets high standards for safety and performance for the equipment used in manufacturing and other industries. Integra Enclosures® meets these benchmarks when designing enclosures to protect against the harsh elements in outdoor surroundings. However, NEMA Type 4 enclosures are also intended to protect equipment indoors, a fact that’s often overlooked.


Regardless of their location, NEMA Type 4 enclosures are manufactured to protect operators as well as the delicate mechanisms enclosed. Enclosures with this NEMA rating offer a degree of protection against potential exposure to hazardous elements. Incidental contact with harmful materials could damage an operator’s health and risk their safety. Businesses are obviously concerned about keeping outside elements from entering enclosures, but keeping equipment protected and working properly is also a safeguard for workers.


The NEMA Type 4 enclosures are sealed tight to fight off the elements. One example of this proficient leak protection is demonstrated inside a car wash. A car wash experiences an excess amount of hose directed water, splashing water and windblown foreign elements. Greenhouses, water parks and mimicked tropical or wetland exhibits at zoos are other indoor locations that need heavily protected housing. The tightly sealed enclosures keep the elements out and equipment running reliably. Spark-induced fires, electrocution injuries and production delays can all be avoided when sensitive equipment is protected from interaction with unwanted elements.


Aside from our NEMA Type 4 enclosures, we also provide enclosures that reach a NEMA 6X rating. Because Integra Enclosures only offers products that achieve the various NEMA ratings, we are able to secure components within enclosures outdoors and indoors.  These two ratings ensure that our enclosures will stand strong in the communications, water, marina, alternative energy and oil and gas industries, among others. As a leading thermoplastic NEMA-style enclosure manufacturer, we’re here to install and modify reliable polycarbonate enclosures to meet your most demanding needs.
