NEMA 2 Electrical Enclosure
NEMA 2 is an improvement of NEMA 1. It provides advanced protection, which is better than NEMA 1. However, the degree of protection is still limited to indoor environments.
In most cases, electrical enclosures with NEMA 1 rating are recommended mainly for indoor applications.
They come in many configurations, material options, and specifications. All these ultimately determine the NEMA 2 enclosure price.
Level of Protection in NEMA 2 Rated Electrical Enclosures
Immediately after the NEMA 1 electrical enclosure, we have NEMA 2. Of course, the NEMA 1 enclosure provides the lowest degree of protection.
When it comes to the level of protection, you should note the following:
- Protects electrical components from accidental contact
- It can protect electrical parts from light splashing of water
- Protection from falling dirt
- Protects systems from large solid particles
From their design, electrical enclosures with NEMA type 2 ratings are mainly suitable for indoor use.
Although the NEMA 1 enclosure will not guarantee protection from liquids, NEMA 2 does.
NEMA 2 Enclosure IP Rating Equivalent
When examining the degree of protection, some available options are – NEMA enclosures andIP enclosures. Well, these are popular protection ratings that are common in the electrical enclosure industry.
When comparing the two, the NEMA 2 enclosure shares many features with the IP 11 rating
They can both protect your electrical components from:
- Falling dirt
- Slight water splashing
NEMA Type 2 Rating and Material Selection
When it comes to choosing these electrical enclosure materials, there are many options for NEMA 2 rated systems. Among the most common materials include:
- Plastic such as polycarbonate and ABS
- Metals including steel, aluminum, and stainless steel
It is important to note that the NEMA 2 rating for electrical enclosures puts more emphasis on the construction design. It is the design that will protect particles from getting into the enclosure.
Comparing NEMA 2 and NEMA 3 Enclosure
NEMA 3 enclosures have an advanced degree of protection. Notably, NEMA 3 enclosures are designed for outdoor applications. Therefore, these NEMA rated electrical enclosures can protect your systems from:
- Rain
- Sleet
- External ice formation
- Windblown dirt
Therefore, their construction is more advanced and robust. However, this is not the case for NEMA 2 electrical enclosures that can only offer protection for indoor applications.
Where to use NEMA 2 Electrical Enclosure
First, electrical enclosures with NEMA 2 rating are suitable for indoor use. In such environments, your enclosure will only be subjected to light water splashing and dirt.
Therefore, in case your electrical devices require basic protection, then the NEMA 2 electrical cabinet offers a perfect alternative. Some common applications include:
- Light industrial settings
- Indoor electrical wiring such as switches, circuit breakers, etc.
Note: Don’t use NEMA type 2 rated electrical enclosure for outdoor applications.
Conclusion
NEMA 2 electrical enclosure providesa limited degree of protection, which is suitable for indoor applications. The degree of protection from these enclosures depends on the construction design.
