Selecting an Industrial Enclosure? Compare and Consider These Enclosure Styles

In a recent blog post, Industrial Enclosure Selection: Getting Familiar with Standards and Ratings, we discussed the main differences between industrial and standard IT enclosures (industrial enclosures are completely sealed when closed). We also discussed the importance of having a basic understanding of the standards that define the degrees of environmental protection by enclosure in order to help to simplify selection.

Comparing IP54, IP66, and NEMA Type 4/4X Enclosures by Application

When you extend your network into nontraditional spaces, you can satisfy most nonhazardous location requirements by focusing on three enclosure ratings: IP54 / NEMA 12, IP66 / NEMA  4 and NEMA 4X. These can be field-adapted with drains, vents, fans or air conditioners as required.

The table below provides a comparison and typical applications:

The table below provides a list of other ratings covered by the three types listed. Note that there are different enclosures (ratings) used in hazardous locations around flammable dust and chemicals, such as mines, refineries, mills and aboard ship. 

How to Choose the Right Enclosure for Your Equipment

Enclosures are typically selected to match equipment mounting requirements according to useable space and size. If the enclosure has 19" EIA mounting rails, then the usable space is according to the rack-mount space and depth of the enclosure. If the enclosure has a panel, then the usable space is based on the panel size and depth of the enclosure. The overall size of the enclosure should provide sufficient clearance to ensure the equipment and connections will fit in the location and provide sufficient air circulation. 

Enclosure Styles 

Once you have determined the enclosure rating you need, then you can work towards selecting the enclosure style and size that best fits your application.

There are four basic styles of industrial enclosures:

Modular Enclosures Modular enclosures are most similar to IT equipment cabinets. Frame includes hinged doors and bolt-on side panels, top panel and bottom panel Leveling feet support the frame or a plinth attaches the frame to the floor  Removable panels allow you to create bays of multiple enclosures to hold larger arrays of equipment, and the frames have a multitude of mounting locations for rails, panels, and accessories  Can be fitted with an assortment of 19" EIA mounting rails for IT equipment or panels for automation electronics Typically have very high load ratings and wide range of accessories for both IT and automation application

Free-Standing Enclosures   Free-standing enclosures are simpler designs, formed as single monolithic enclosures in specific sizes used as stand-alone enclosures.   Single door or front and rear doors Support panels for mounting automation, controls, or instrumentation electronics Specific size enclosures may include 19" EIA mounting rails for IT equipment

Floor-Mount Enclosures Floor-mount enclosures are similar to free-standing enclosures formed as single monolithic enclosures in specific sizes used as standalone enclosures.    Elevated above the finished floor adding clearance and easier cable access Typically wider with double doors Have a large panel for mounting automation electronics, controls and instrumentation Do not include 19" EIA mounting rails for IT equipment.

Wall-Mount Enclosures  Wall-mount enclosures attach to the wall and support smaller amounts of equipment.  Two basic styles Swing-out style is hinged at the rear so you can access the back of equipment. This style can be fitted with 19" EIA mounting rails for IT equipment or panels for automation electronics  Fixed style has front-only access, and may also feature both 19" EIA mounting rails and panels or just panels
