NEMA 6P Enclosures

NEMA 6P-rated electrical enclosures and boxes provide the ultimate protection for submersible or watertight applications. Meeting the NEMA 6P rating ensures the enclosure will safeguard sensitive equipment in harsh environmental conditions, including washdowns and complete submersion for a prolonged period of time. NEMA 6P junction boxes are available in durable plastic or metal materials and are corrosion-resistant. Trust your submersible enclosure project to the experts at Polycase. All Polycase NEMA enclosures undergo testing and certification by UL.

With a range of options and sizes to choose from, we make it easy to find the right NEMA 6P enclosure solution to fit your needs. Read more below to learn about what NEMA 6P enclosures can offer and how to choose the best option for your application.

What Is a NEMA 6P Enclosure?

NEMA 6P is the most protective enclosure type on the NEMA rating scale. These are the main characteristics of a NEMA Type 6P enclosure:

  • Total protection against falling dirt, windblown dust, and other particulate hazards
  • Waterproof against common water ingress hazards including rain/snow/sleet, splashing, and/or hose-directed water
  • A high degree of protection against ingress of water from occasional prolonged submersion, up to any limited depth specified by the manufacturer
  • Suitable for indoor or outdoor use, but primarily used in outdoor applications

See our full guide to NEMA enclosure ratings for more key information on the NEMA scale. Check out our NEMA 6P applications guide as well, where we dive into some of the practical applications of this tough rating.
