ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ
What is a NEMA 12 enclosure?
A NEMA 12 enclosure is a type of electrical enclosure designed for indoor use in industrial settings. It protects against dust, dirt, lint, fibers, and dripping non-corrosive liquids. These enclosures are commonly used to house control panels, relays, and other sensitive electrical or electronic components.
What is the difference between NEMA 12 and NEMA 4 enclosures?
The key difference lies in water protection:
NEMA 12: Protects against dust and dripping water; suitable for indoor, dry environments.
NEMA 4: Protects against hose-directed water and even occasional submersion; can be used outdoors or in wash-down areas.
If your application involves water spray or outdoor exposure, NEMA 4 is a better choice.
Is a NEMA 12 enclosure waterproof?
No. NEMA 12 enclosures are not waterproof. They are resistant to light dripping or splashing but not designed for high-pressure water or full submersion. For waterproof performance, consider NEMA 4 or 6 enclosures.
Where are NEMA 12 enclosures typically used?
Они широко используются в:
Manufacturing plants
Warehouses
Data centers
Food processing (dry areas)
HVAC system control rooms
CNC machine panels
Industrial automation and robotics
Are NEMA 12 enclosures UL Listed?
Yes, most high-quality NEMA 12 enclosures are UL Listed and CSA Certified, ensuring they meet rigorous safety and performance standards. Always verify certifications when purchasing.
Can NEMA 12 enclosures be used outdoors?
No. NEMA 12 is for indoor use only. For outdoor environments, use a NEMA 3R, 4, or 4X enclosure, depending on exposure to weather, wash-down, or corrosive substances.
What materials are NEMA 12 enclosures made from?
Common materials include:
Carbon steel (powder-coated) – Most widely used for general industrial use.
Stainless steel (304 or 316) – Used in environments where hygiene or corrosion resistance is required.
Aluminum or polycarbonate – Less common, but available for lightweight or specialty applications.
Are custom NEMA 12 enclosures available?
Yes. Many manufacturers offer customizable options including:
Size and mounting
Cutouts and knockouts
Painted finishes
Door types (hinged, double-door, locking mechanisms)
Internal mounting panels or DIN rails
