NEMA 4 Enclosure

In harsh industrial environments and outdoor settings with unpredictable weather, ordinary weatherproof boxes are not enough. High-pressure water, chemical washdowns, and corrosive salt can put sensitive electronics and critical systems at risk.

ArmorLogix NEMA 4 and NEMA 4X aluminum electrical enclosures are engineered for these exact challenges. Manufactured from marine-grade 5052 aluminum, these protective housings for electrical equipment provide complete water protection while maintaining natural thermal conductivity. The result is an enclosure that keeps your investment cool, dry, and protected, meeting National Electrical Manufacturers Association (NEMA) standards for the most challenging environments.

What NEMA 4 and NEMA 4X Enclosures Mean for Your Project

Our selection of NEMA-rated enclosures is suitable for numerous applications, and your choice of model should be based on the operational environment. It’s essential to consider whether your equipment will be exposed to more than just the elements, such as daily washdowns, dust and debris, or aggressive cleaning routines. NEMA 4 and 4X enclosures are tested and rated to meet the toughest demands, providing robust, watertight protection both indoors and out.

The tight sealing of ArmorLogix NEMA 4 and 4X enclosures provides a high safety factor, protecting against:

• Powerful hose-directed water
• Forceful cleaning with water jets or sprays
• Severe weather conditions and water events, including driving rain, sleet, and snow
• Fine, windblown dust and dirt
• Corrosive exposure, including salt or chemicals
• Ice formation

This makes NEMA 4 or 4X the right choice for industrial, manufacturing, and high-risk outdoor environments, as they will provide long-term, worry-free protection.
