The question in terms of which electrical enclosures are suitable for your application environment and give enough protection to your equipment but not overwhelming and make you overpay for it.
Nema box ratings.
Nema 6 6p offering the same protection as a nema 4 enclosure nema 6 offers protection from temporary or prolonged 6p nema rating water submersion up to a designated depth.
Nemaco provides quality electrical enclosures that adhere to nema rating standards.
Nema 7 also built for hazardous locations a nema 7 enclosure is explosion proof and made for indoor use built for hazardous locations.
In the electrical world nema stands for national electrical manufacturers association an association of us based equipment manufacturers that produce standards used by many equipment manufacturers.
Nema ratings enclosure types.
Nema vs ip ratings table.
Nema standards describe each type of enclosure in general and functional terms and specifically omits reference to construction details.
We offers designs that adhere to 6 different nema enclosures ratings.
Nema enclosure ratings are similar to iec ip codes and can offer the same protections but cannot be mapped directly.
Enclosures constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment and to provide a degree of protection against falling dirt.
See ip codes nema.
Nema is a rating system for equipment that might be exposed to liquids rain ice corrosion and contaminates such as dust.
Words like waterproof weatherproof water or rain resistance corrosion resistance and the like.
For instance an enclosure with a rating of ip10 would offer less protection than an enclosure that is rated at ip54.
Nema ratings for enclosures.
There is not a direct correlation between nema ratings and ip ratings as the two systems are based on a different set of variables.
At nema enclosures our knowledge and experience in nema rated enclosures is so extensive it s in our name.
In other words nema specifies what an enclosure must do not how to manufacture it.
If unsure of the enclosure rating that is required of your project please refer to the design chart below.
Ip code iec ingress protection code a similar standard.
Each of these ratings indicate different levels of protection against ingress of solids and liquids.
Nema enclosure ratings define where an enclosure was designed to be used and the level of protection it was designed to provide.
The chart will assist in specifying which enclosure rating is appropriate for the environment and application needed.
The following table summarizes the various ip number designations.
Nema rating ip equivalent nema definition protection against solids protection against liquids.
Nema connector another common but mostly unrelated set of standards from nema.
The national electrical manufacturer association nema uses a standard rating system that defines the types of environments in which an electrical enclosure can be used and frequently signifies a fixed enclosure s ability to withstand certain environmental.
Nema 3r 4 4x 6 6p and 12.
