What Is a NEMA 2 Enclosure?
NEMA 2 enclosures are designed for indoor use, offering protection against light drips, splashing water, and limited dust ingress. NEMA 2 enclosures are a step up from NEMA 1 enclosures because they provide protection from liquids that NEMA 1 enclosures don’t offer. They provide this protection through durable design that helps the enclosures shed liquids from their surface and keeps them tightly sealed against dirt.

Why Choose NEMA 2 Enclosure?
Based on over a decade of enclosure manufacturing experience, we’ve seen how incorrect enclosure selection leads to costly downtime. For instance:
Case Example: A manufacturing client in Ohio experienced repeated relay failures due to high ambient humidity and light condensate near their electrical panels. After switching from NEMA 1 to NEMA 2 enclosures, failure incidents dropped by 90% within 3 months, saving over $12,000 in repair and loss costs.

PREGUNTAS FRECUENTES
What does a NEMA 2 enclosure protect against?
NEMA 2 enclosures are designed for indoor use, offering protection against limited amounts of falling water (like dripping or splashing) and light levels of dust. They are suitable for locations with moderate humidity, such as mechanical rooms, basements, or near industrial washdown areas (non-direct).
How is NEMA 2 different from NEMA 1 or NEMA 4?
NEMA 1 provides only basic protection against contact and dust.
NEMA 2 adds drip protection, making it better suited for damp environments.
NEMA 4 is fully waterproof and suitable for outdoor or washdown environments.
If your application is indoors with occasional moisture exposure but doesn’t require full waterproofing, NEMA 2 is a cost-effective middle ground.
Can I use a NEMA 2 enclosure outdoors?
No. NEMA 2 enclosures are not rated for outdoor use. They lack protection against rain, windblown dust, and UV exposure. For outdoor environments, consider NEMA 3, 3R, or 4/4X enclosures depending on your specific requirements.
Are NEMA 2 enclosures waterproof?
Not exactly. They are drip-tight, meaning they can resist vertically falling water or light splashes, but they are not sealed against high-pressure water, heavy condensation, or immersion. For true waterproofing, you’ll need NEMA 4 or 6-rated enclosures.
What materials are typically used for NEMA 2 enclosures?
Most NEMA 2 enclosures are made from:
Powder-coated cold-rolled steel (most common for dry environments)
Stainless steel (for mildly corrosive or humid interiors like food processing zones)
The material choice depends on your environmental exposure, aesthetics, and durability needs.
Are NEMA 2 enclosures UL certified?
Yes, reputable manufacturers provide UL 50 / 50E listed NEMA 2 enclosures. Always check for UL labeling if third-party certification is required by your application or jurisdiction.
What types of equipment are housed in NEMA 2 enclosures?
They are commonly used to protect:
Control panels
Terminal blocks
Power distribution units
HVAC or lighting system controls
…in indoor commercial or light industrial environments.
Do NEMA 2 enclosures have gaskets?
Yes. A drip-tight neoprene or EPDM gasket is typically fitted between the enclosure body and door to seal out moisture and dust. Regular inspection and replacement of gaskets is recommended for long-term performance.
