NEMA 4X Electrical Enclosures
NEMA 4X electrical enclosures are typically used in extreme, harsh, and corrosive environments that exceed the capabilities of NEMA 4 enclosures. NEMA 4X enclosures are generally manufactured using made of 304 & 316 stainless steel because of it's high degree of protection from corrosive materials.
NEMA 4x applications include food, such as meat/ poultry processing facilities, where total washdown with disinfectants occur repeatedly and petro-chemical facilities, including offshore petroleum sites.
NEMA 4X Enclosure Characteristics:
- Indoor or outdoor use, including offshore applications
- Protection against windblown dust and rain
- Protection from splashing water and hose-directed water
- Corrosion-resistant
The steel, stainless steel or aluminum enclosures is an infiltration-resistant enclosure with superior corrosion protection beyond the NEMA 4 standard, yet priced to compare with low cost competitors.
The final bonus comes on the job site, in a ready-to-install unit that requires less modification and speeds the implementation process.
