How is NEMA 4X different from NEMA 4?

NEMA 4X is the same as NEMA 4, except it offers extra protection against corrosive agents, such as alkaloids, acids, and highly polar solvents like acetone and MEK.

Usually, this is due to the materials used.

Are NEMA 4X enclosures used outdoors?

NEMA 4X enclosures are very often used outdoors, as well as indoors in industrial places.

Because of the type’s protection against water and corrosion, it is perfectly suitable for the outside.

What is the standard NEMA 4X enclosure configuration?

The standard configuration we provide is a gland plate with modules for cable entry, ground connections, fluorescent lamps with a switch, a radiating fan, PU gaskets.

NEMA 4X enclosures should also be marked if they require waterproof fittings, conduit connections, and mounting hubs.

You can also request any other feature you need.

What are the common applications for NEMA 4X enclosures?

NEMA 4X enclosures are used mainly for industrial applications. 

These include electrical hydraulic or pneumatic control box, terminal or junction wiring enclosures, operator interfaces, and consoles with corrosion-resistant properties.

Because of this type’s resistance to water, these enclosures are often found in marine or naval applications, transportation industries, and various municipalities like water treatment plants.

Furthermore, irrigation systems and process industries heavily rely on 4X enclosures.

Why?

Well, such industries work with various chemicals like fertilizers, minerals, petroleum, alkalines, etc.

Also, food processing factories, pharmaceutical factories, and even research institutions need corrosion-resistant enclosures to withstand frequent sanitization and leakage of chemicals.

How are NEMA 4X enclosures tested?

You can refer to the latest NEMA 250 document for requirements of self-declaration of NEMA-этикетки.

NEMA 4X is tested using the external icing test, the hose down test, the outdoor corrosion test, the gasket test, and an additional 4X corrosion test.

Испытание на внешнее обледенение включает в себя опрыскивание корпуса водой с последующим охлаждением помещения до тех пор, пока на корпусе не образуется слой льда толщиной 20 мм.

External icing test

 External icing test
По окончании испытания корпус должен быть неповрежденным и работоспособным.

Outdoor corrosion test involves making a 5% sodium chloride solution and spraying it onto the enclosure continuously for 200 hours (8.3 days).

The hose down test sprays water at a rate of 246 liters per minute for as long as it takes to test all weak points like seams, joints, fittings, and other such places.

Hosedown test

 Hosedown test
NEMA 4X enclosures also undergo various gasket tests to evaluate how they age while stretched at high temperatures.

As long as there are no cracks, deformations, and the tensile strength remains the same, the enclosure passes this test.

It is needed because good gaskets are key to good protection against water ingress.

Why does the 4X corrosion test require only 200 hours of testing instead of 600?

This is because the 4X corrosion test requires the enclosure to be compared with 304 steel, instead of galvanized steel, as is the case with outdoor corrosion test.

In other words, a different comparison standard calls for a different test duration.

How can I be sure of the quality of NEMA 4X enclosures?

В KDM у нас есть Сертификация ISO9001 которые вы можете просмотреть.

Кроме того, вы можете провести независимое стороннее тестирование корпусов, если вам необходимо подтверждение качества и оценка соответствия.

What is NEMA 4X in IP standards?

Although it is difficult to translate one set of standards into another, NEMA Type 4X is similar to IP55 and IP66.

NEMA и IP

  NEMA и IP 

Влияют ли заглушки, вентиляционные отверстия, фитинги и т. д. на рейтинг корпуса?

Individual fittings, vents, knockouts, etc —ideally —should have a better NEMA rating than the enclosure itself.

However, this may not be possible, so these features should have the same rating as the overall structure.

If they have a lower rating, the rating of the entire enclosure goes down.

The most vulnerable place in an enclosure is between its body and its lid – here is where dust, moisture, and corrosion can creep in.

However, KDM designs sealing gaskets that are either moulded or screwed in place flush against the surface.

PU sealing gaskets

What are common designs for NEMA 4X enclosures?

Some common designs for NEMA 4X enclosures include free-standing, floor-mounted, wall-mounted, and custom.

Отдельно стоящий, напольный, and walk-in enclosures are all used for bigger equipment.

Они могут иметь одну или несколько дверей, в зависимости от ваших требований.

Such enclosures can also have pedestals, casters, leveling feet, and lifting eyes to help install and move them around.

Какие дополнительные функции часто включаются?

Вы можете заказать вентиляционные отверстия, окна, распашные двери, замки, системы управления кабелями и многое другое.

Вентиляционные отверстия, as well as radiating fans, provide a path for heat to escape through.

They cool down the electrical components of the enclosure.

Вентиляционные отверстия обеспечивают более пассивный поток воздуха, тогда как вентиляторы активно перемещают воздух и используются для охлаждения оборудования, которое быстро нагревается.

This prolongs the life of the equipment and decreases the possibility of malfunctions and electrical fires like дуговая вспышка.

Если вы хотите предусмотреть дренажное отверстие, также следует предусмотреть съемную заглушку.

File pockets store operating manuals; drip caps protect the enclosure from splashing water; solar shields protect against UV rays; switches and lights help operate the equipment inside the enclosure.

How do NEMA 4X enclosures maintain temperature?

Как правило, корпуса могут быть оснащены кондиционерами, охладителями, теплообменниками и нагревательными полосами для контроля температуры внутри корпуса.

This prevents the equipment from overheating or freezing.

If your enclosures are for cold environments, then heat exchangers and heater strips may be necessary.

Теплообменники представляют собой замкнутые системы, которые просты в обслуживании.

As equipment works, it may heat the air around it, and heat exchangers push hot air into colder compartments, which results in an equalized temperature and pressure.

Теплообменник

Мощность обогревателей для корпусов варьируется от 50 до 1200 Вт в зависимости от размера вашего корпуса.

Air conditioners and various air coolers are vital for enclosures situated in warm environments.

Equipment needs to be cooled down to prolong its life.

What materials are used for NEMA 4X enclosures?

Их можно сделать из оцинкованная сталь, и нержавеющая сталь – обычно марок 304, 316 или 316L.

We do offer carbon steel, but it is not the best for 4X enclosures since this steel is more vulnerable to corrosion.

Stainless steel, on the other hand, is perfect for NEMA 4X.

It is created by adding chromium, nickel, and molybdenum to the iron-carbon alloy.

Нержавеющая сталь против оцинкованной стали

 Нержавеющая сталь против оцинкованной стали
Стали марок 304 и 316 различаются по содержанию всех добавок.

316 stainless steel provides the best protection against salt spray, certain acids, and high temperatures.

This is why 316 is used more for marine applications.

Meanwhile, 304 resists sulfates and chlorine more.

Оцинкованная сталь покрыт защитным слоем цинка, предотвращающим коррозию.

Этот тип стали дороже и тяжелее нержавеющей стали.

При использовании стали производитель должен учитывать определенный калибр или толщину листового металла, необходимую для соответствия стандартам NEMA.

NEMA 4X enclosures use 16 or 14 gauge steel, which is about 1.6-2 mm.

Стекловолокно очень прочен, может рассеивать тепло и изолирует электричество, снижая влияние помех и вероятность поражения электрическим током.

Он изготовлен из стекловолокна, помещенного в пластик.

Корпуса также могут быть изготовлены из алюминиевых сплавов.

Они не обязательно лучше стальных сплавов, но могут быть лучше в зависимости от того, что вы собираетесь использовать и каковы ваши потребности.

Как и марки стали, алюминиевые сплавы могут относиться к сериям 5052 или 6061.

Алюминий против нержавеющей стали

Оба материала легкие, но 5052 лучше поддается сварке, тогда как 6061 имеет более высокую устойчивость к коррозии.

Кроме того, 6061 стоит дороже.

Алюминий имеет верхний слой оксида, который предотвращает коррозию.

For NEMA Type 4X enclosures, stainless steel grade 304, polymers like fiberglass, and aluminum 6061 are most recommended.

What paints and coatings can be used for NEMA 4X enclosures?

Наши корпуса хорошо защищены, но правильное покрытие может дополнительно усилить защиту.

Покрытие Alodine, также известное как хроматное конверсионное покрытие, используется для грунтования стали и алюминия под покраску, а также для предотвращения коррозии.

Покрытие алодином

Покрытие алодином
This is a cheaper process than anodizing, and can be recognized by its characteristic greenish-yellow hue unless it is painted over.

Вы можете выбрать эмалевое или порошковое покрытие любого цвета.

Порошковая краска is deposited with the electrostatic force and is quicker and easier than enamel.

Кроме того, он более гибок внешне, что дает возможность выбирать глянцевую и матовую отделку.

Порошковое покрытие

Порошковое покрытие
Эмалевая краска has a glossy finish and is weather-resistant.

Анодирование Покрытие использует аноды для окисления металла, обычно алюминия, с целью увеличения его толщины и повышения коррозионной стойкости.

Anodizing a 4X aluminum enclosure can definitely be a plus.

Steel is not typically anodized because it can actually speed up its corrosion.

There can also be anti-graffiti and anti-poster coatings to protect your enclosure from vandalism if you plan to install it outdoors.

NEMA 4X enclosures most often use powder coating, but epoxy enamel and PU enamel are also great for industrial enclosures.

Мы можем предоставить любое покрытие в любом цвете и отделке, поэтому связаться с нами сегодня!

How can symbols be put on a NEMA Type 4X enclosure?

You can customize your enclosure with our engraving and silk-screening services.

Silk Screening is the easiest and most affordable method.

Any flat side of the enclosure can be silk-screened with labels, warnings, serial number, your company name, logo, and anything else.

Although, beware!— silk-screening on stainless steel or aluminum can be worn or scratched off.

However, a clear powder coat can help prevent that.

Шелкография

  Silk-screening
Engraving the enclosure is your second choice of customizing your enclosures.

Этот вариант более затратный и занимает больше времени, но он и более долгосрочный, чем шелкография.

Обычно с поверхности удаляется около 0,005 или 0,010 дюйма металла.

После удаления металла его заливают эпоксидной краской любого цвета в соответствии с вашими требованиями.

Гравировка

Гравировка
Помимо символов должны быть и другие обозначения.

Если оборудование необходимо установить в определенной ориентации, это должно быть указано на корпусе.

Also, areas where live parts will also have to have a mark.

Любые предупреждающие или опасные знаки также должны быть выгравированы или нанесены методом шелкографии на корпус.

На что еще следует обратить внимание при заказе корпуса?

Есть несколько распространенных ошибок, которые совершают люди.

К ним относятся выбор неправильного типа NEMA, неправильного материала, неправильного размера, неправильной конструкции и игнорирование характеристик.

NEMA 4X is built for non-hazardous, indoor and outdoor locations with normal air pressure, rain or dripping water, some dust, snow, sleet, and ice.

NEMA 4X usually uses stainless steel 304 or aluminum to increase resistance to corrosion.

Размеры и конструкция корпуса зависят от конкретного электрооборудования, которое вы планируете там разместить.

However, NEMA 4X enclosures are usually medium-sized or big.

Another note is that if you are choosing stainless steel, be prepared that it is not stain-free.

Sometimes, corrosion does show in the form of mild staining, but it is easy to get rid of with just water.

Что касается дизайна и характеристик, то они зависят от конкретного случая, поэтому проконсультируйтесь с производителем за совет.
