Understanding of Nema 4x Specifications

O Nema 4x enclosure provides the protection to electrical components under different environments. Either its rain, moisture, heat, or corrosion, all the components are safe by it. The 4 in the Nema 4x indicates the resistance against the moisture and dust while the x indicates the corrosive resistance.

The enclosure is made from special materials to fight against harsh chemicals and washdowns. Selecting the Nema 4x ensures long-life and safety of equipment and also minimizes the maintenance cost.

Key Features of Nema 4x Enclosures

Choosing the right Nema 4x enclosures according to the environment is an important step. Understanding the key features of Nema 4x enclosure enables you to select the right one according to your needs. Here are some key features:

Resistência à corrosão: As the enclosures are installed outside, it is important to ensure that it prevents corrosion. The Nema 4x enclosures prevent the electrical components from corrosion.
Rain and Dust Resistance: The Nema 4x enclosure protects against the dust, rain, moisture and harsh weather conditions. So if you are from a rainforest area then Nema 4x should be your first preference.
Durable and Reliable Material: The materials of the Nema 4x enclosure are durable. The stainless steel, fiberglass and polycarbonate are used to make the enclosures.
Protection from UV Rays: The enclosure is designed in such a way that they are able to bear harsh ultraviolet radiations.
Safe and Secure Sealing: The enclosures are well sealed in order to stop contamination and moisture from entering inside.
Meeting Industrial Standards: All the enclosures meet the Nema and the UL industrial standards and they also pass through all the quality tests.
Drainage and Ventilation System: The enclosure is well-designed in such a way that they have vents and drain plugins to manage inside condensation.
Customized Design: You can design the enclosures according to your need. The size, cutout and all the internal mounting can be easily customized.

Material & Construction of Nema 4x Enclosure

Material of Nema 4x Enclosure

The material of the Nema 4x plays an important step for checking the reliability, resistance and suitability. Here are some materials used to make Nema 4x enclosures:

Stainless Steel (304 and 316 Grade): The enclosure is made of stainless steel. The 304 stainless steel helps to fight against corrosion outdoors. The 316 stainless steel provides protection against the harmful chemical. The enclosures made of stainless steel are used in marine environments and in chemical industries.
Fiberglass Reinforced Polyester: The fiberglass reinforced polyester provides the best protection against the corrosions, UV rays and harsh chemicals. The enclosures made out of such material are used in telecommunication and electrical fields.
Aluminum: The aluminum is considered to be a lightweight material that has heat resistant properties. The enclosures are also powder painted with aluminum in order to stop corrosion. The enclosures made of aluminum are best suitable for high-temperature areas, and in distribution systems.
Polycarbonate: The polycarbonate is the light material but has a high impact. It helps to prevent degradation and yellowing. The enclosure made of polycarbonates is best suitable for outdoor and telecommunication fields.

Construction of Nema 4x Enclosure

The construction of the Nema 4x enclosure is done in such a way that it passes all the quality tests. Here are important steps of construction of Nema 4x enclosures:

Material Selection: The first step is the material selection. Either stainless steel, fiberglass reinforced polyesters, polycarbonate or the aluminium is selected. The material selection entirely depends on the environment condition.
Welded Design: The next step is welding to minimize the gaps if any on the surface. It helps to prevent water, dust, and contamination from entering inside the enclosure.
Doors and Panels Reinforcement: The doors to be placed at the enclosure are constructed with the hinges. This helps to prevent the damaging of the door on frequent opening and closing.
Locking System: The important step is to install the secure locking system. The enclosure is secured with the keyed locks, padlock provisions and latches.
Surface finishing and Coating: the next step is the finishing and coating of the enclosure surface. This is done to save the enclosure from the corrosion.
Drainage and Ventilation System: The drainage and the ventilation system is installed according to user need. The filtered vents installed in the enclosure are designed in such a way that it maintains the air flow but doesn’t allow any dust and containment entering inside the enclosure.
Pre-drilling: The last step is to pre-drilled mounting flanges in order to provide a secure and quick installation of the enclosure.

Applications of Nema 4x
