NEMA 2 Enclosure
Find the right balance of performance and cost with our wide range of NEMA 2 enclosure options. At Bison Profab, we provide high-quality electrical enclosures made from aluminum, cold-rolled steel, and stainless steel. Our NEMA 2 enclosure products are an excellent choice for manufacturers, telecom providers, energy companies, and many other industrial businesses.
NEMA 2 Electrical Enclosure Specifications
The NEMA 2 rating applies to indoor electrical enclosures with moisture protection features. NEMA 2 enclosures resist:
- Dirt and debris
- Light dust
- Dripping water and oils
- Minor splashes
- Ambient moisture
Drip-tight NEMA 2 enclosures are fitted with drip shields to protect electrical components from falling or splashing water in high-condensation environments, such as cooling rooms or washrooms. Models with locking doors are good for access control and tamper prevention.
Factors To Consider When Choosing a NEMA 2 Electrical Enclosure
Moisture can cause significant damage to electrical components, control systems, and electronic parts:
- Electrocution hazards
- Fire risks
- Short circuits
- Damage to connected devices
- Malfunctioning components
Even excess humidity is a problem for connectors, potentially triggering corrosion/oxidation and preventing normal electrical flow.
The Importance of Moisture Protection for Electrical Systems and Electronic Parts
Some organizations choose polycarbonate enclosures, but we don’t recommend them. Plastics simply don’t provide the durability, impact resistance, or security that industrial applications require. Metal NEMA enclosures offer excellent durability and strength:
Stainless Steel
Stainless steel is a premium option that delivers outstanding corrosion resistance. It’s ideal for drip-tight NEMA enclosures in oil & gas, petrochemical, food processing, and beverage manufacturing applications.
Aluminum
Aluminum is naturally resistant to rust and other types of corrosion. It’s also lightweight, making it easy to install on equipment. Aluminum enclosures with casters are popular for systems that need to move from one part of a factory to another.
Cold-Rolled Steel
Steel provides heavy-duty protection for areas with a higher risk of impacts. CRS is also relatively inexpensive, allowing you to customize enclosures while still keeping overall costs down. Unfortunately, bare steel is vulnerable to rust, so it needs a galvanizing coating, powder-coat finish, or protective paint layer.

Common Applications for NEMA 2 Enclosures
NEMA 2-rated enclosures are a good fit for industrial areas where indirect moisture exposure or ambient moisture is a concern, such as automotive repair bays and manufacturing centers, consumer goods processing plants, wastewater treatment plants, and alternative power generation facilities.
Drip-tight NEMA enclosures for telecommunications are generally free-standing, with vents to prevent overheating. Telecom providers often choose custom systems with mounting racks for improved cable management, power distribution, security, moisture protection, and cooling systems. We also design NEMA 2 (or NEMA 4 for high-moisture cutting processes) enclosures for industrial automation systems.
NEMA 2 Versus NEMA 1 Enclosures
NEMA 2 (IP 11) electrical enclosures offer the same level of dirt protection as NEMA 1 (IP 10), but NEMA 2 enclosures are drip-tight and prevent water infiltration. The price difference is minor.
