DEFINITION WITH GENERAL REFERENCE APPLICATIONS

Definition: NEMA 4X Enclosures provide protection against solid objects such as falling dirt, circulating dust, airborne dust, and windblown dust. Similarly, they give the same level of protection against ingress of water, dripping, light splashing, splashing and hose down (directed) water.

General Note Type 4X Enclosures

NEMA 4X Enclosures are very similar to NEMA 4 Enclosures in terms of protection. They both provide the almost same standard level of protection except the NEMA 4X rating requires corrosion resistance, therefore, stainless steel is more commonly used in enclosures and cabinets in industrial application. Sometimes fiberglass (FRP) or plastic materials might be used in small enclosures or junction boxes. As a general rule, most industrial customers prefer stainless steel since the materials are corrosion resistant and rugged.

NEMACO™ Offers Several Types of NEMA 4X Electrical Enclosures

Wall Mount Enclosures

Floor Mount Enclosures

Mobile Wheels Enclosures

Double Bay (Doors) Enclosures

Climate Control Enclosures

Alternate Material and Coatings for NEMA 4X Enclosures

NEMACO™ manufactures NEMA 4X Enclosures primarily with quality grades of stainless steel, that provides protection from corrosion. Because the characteristic of stainless steel is not corrosive. However, stainless steel does have a disadvantage side, it is a heavy material. Therefore NEMACO™ offers other materials that approximately comparative to be NEMA 4X (protect from corrosion), powder coating carbon steel and aluminum for corrosion protection as an option for your applications.

Each of the ferrous and non-ferrous raw materials has specific and unique qualities that make an enclosure optimum based on the application, therefore the different materials show several characters and capabilities that make enclosures unique and specifically suited for certain environments and applications.

STAINLESS STEEL Type 4X enclosure

We are very proud to offer you our NEMA 4X Enclosures for industrial applications used for control panels, distribution cabinets, and other SCADA applications. NEMACO™ offers NEMA type 4X electrical enclosures manufactured per NEMA (National Electrical Manufacturer Association) standards to ensure top quality to our customers.

POWDER COATED ALUMINUM

As mentioned in the previous information, stainless steel is the first choice by engineers and maintenance crews for industrial
