NEMA 3RX Rating Now Offered

Nema Enclosures Mfg. is proud to announce that we are now offering NEMA 3RX rated – UL Listed enclosures. These enclosures offer the same great ingress protection as our 3R enclosures, but with an added level of corrosion protection.

Corrosion is a major problem in nearly every U.S. industry sector, costing an estimated $276 billion per year. Carbon steel is susceptible to natural oxidation (rust) and galvanic corrosion. A wide variety of environmental factors can influence the severity of the corrosion and can be difficult to predict accurately. Temperature, humidity, and sulfur dioxide concentration in the atmosphere can all play a role in the rate of corrosion. Environments near the ocean, such as docks, shipyards, and oil platforms are all at risk for heavy sea salt spray.

Put your corrosion worries at ease by choosing a NEMA 3RX enclosure. Nema Enclosures manufactures NEMA 3RX enclosures out of 5052-H32 aluminum, 304L stainless steel, or 316L stainless steel in a wide variety of different styles to meet your application. These material types offer an inherent degree of protection against corrosive agents such as a salt spray, without the need of an additional coating.

NEMA 3RX enclosures are designed with the same corrosion resistance as NEMA 4X, but since they are not required to be dust tight, louvers and other ventilation options can be added. NEMA 3RX enclosures also have the added benefit of being cheaper than their 4X counterpart.

Type 3RX enclosures are 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 (rain, sleet, snow); that will be undamaged by the external formation of ice on the enclosure that provides an increased level of protection against corrosion.

There are five primary ingress protection tests associated with NEMA 250 Type 3RX enclosures:

  • Access to hazardous parts
  • Ingress of solid foreign objects (falling dirt)
  • Ingress of water (dripping and light splashing)
  • Ingress of water (rain, snow, and sleet)
  • Corrosive agents

Common applications for these enclosures include:

  • Power distribution
  • Telecommunications
  • Junction boxes
  • HVAC equipment
  • Farm equipment
  • Meter Cabinets
  • Utility boxes

NEMA 3RX enclosures provide an economical choice for an outdoor application that requires corrosion protection.
