The National Electrical Manufacturers Association serves as the respected source for the electrical industry’s standards. The purpose of NEMA standards is to reassure consumers the products they are buying will meet certain levels of performance and quality essential for protecting mission-critical electronics and other components. The standards are based on testing and cover concerns such as safety, construction tolerances, service life and other qualifications. Integra Enclosures® works hard to meet these standards and one example is our NEMA Type 6P enclosures, which have built a proven track record in wastewater and marine applications.


NEMA defines a Type 6P enclosure as:


Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (hose directed water and the entry of water during prolonged submersion at a limited depth); that provides an additional level of protection against corrosion and that will be undamaged by the external formation of ice on the enclosure.”


Because Integra enclosures meet the NEMA Type 6P standards, companies know they can trust the enclosure to protect the components inside against water. Unlike most other enclosure companies, we build Type 6P enclosures with polycarbonate materials, which is one reason they are able to keep interiors safe and dry.


Although polycarbonate was not originally the industry standard it is becoming the standard, polycarbonate provides strong competition in the enclosure community to more traditional materials such as fiberglass or stainless steel. Polycarbonate beats out competitors in various categories and one of the most significant features is its durability. One common use of polycarbonate is bulletproof windows, which says a lot about its reliability and resistance to impact. Fiberglass has an average tensile strength of 220 inches/pound compared to polycarbonate’s 900 inches/pound average tensile strength. That kind of strength helps the enclosure stand up to the pressures of underwater installations, and also is testimony to the enclosure’s ability to withstand unexpected incidents in outdoor locations, where an impact is always possible. Vulnerable contents will remain safe inside, and the enclosure itself will retain its strength and resilience over time.


Integra Enclosures produces both NEMA Type 4X enclosures and NEMA Type 6P enclosures to meet the demands of harsh environments. To learn more about our entire line of products, speak with an Integra sales associate over the phone at (440) 269-4966.
