When selecting an electrical enclosure, it’s important to choose a size that offers plenty of room for your device’s components. The enclosure must give the components enough breathing room to avoid excess heat rise and must provide sufficient space for the device assembly process. For devices that need plenty of space inside their enclosures, 24 x 24 inches is one of the largest standard NEMA enclosure sizes available. These super-sized enclosures are ideally suited for larger electrical and electronic devices. In this article, we’ll talk about when a 24 x 24 enclosure might be the right choice for your application, and we’ll look at some high-performance 24 x 24 enclosures that Polycase offers. Electrical control panels are among the most common applications for 24 x 24 enclosures.

Use Cases for 24 x 24 Enclosures

Some applications demand a large enclosure. Applications with any or all of the following characteristics may necessitate a 24 x 24 enclosure:
  • Large and bulky devices
  • Devices with numerous controls
  • Devices that need space for a heat load to dissipate
  • Devices with many electrical or data connections
  • Devices with complex assembly processes
Some of the common use cases for large electrical or electronics enclosures include:
  • Industrial Control Panels: The complex control panels required for industrial machinery often require large enclosures, particularly if they have buttons or switches with high profiles.
  • Breaker Boxes: Breaker panels for even a small structure usually require a large electrical enclosure.
  • Lighting Control Boxes: Sophisticated lighting systems often require large and complex control panels that are best housed inside a durable electronics enclosure.

Specifications for 24 x 24 Enclosures

Think carefully about which features and specifications your 24 x 24 enclosure needs to include. Consider the following factors:
  • NEMA Rating/IP Rating: An enclosure’s NEMA or IP rating specifies the protective qualities that it offers against environmental hazards. Read our complete guide to NEMA ratings and guide to IP ratings to learn more.
  • Material: Different enclosure materials have properties that make them suitable for different applications. See our guide to enclosure materials for a full analysis of each material’s pros and cons.
  • Security: Many types of equipment need secure enclosures that can’t be accessed by unauthorized personnel. Thus, your enclosure may need to be lockable or include a space for a padlock. Both of Polycase’s 24 x 24 enclosure models include built-in keyed locking mechanisms.
  • Mounting Features: Your enclosure may need to include internal or external mounting features to achieve its purpose. External features may include mounting flanges or mounting feet. Internal features include mounting bosses, bonding studs or mounting panels. Polycase’s 24 x 24 enclosure models both include mounting feet and internal mounting panels.
  • Accessories: Your application may require outfitting your enclosure with accessories, such as DIN rails, enclosure vents or cable glands. Browse our full selection of enclosure accessories to find the accessories your enclosure needs, or choose an enclosure like our Polycase SA Series models that come with all necessary hardware included.

24 x 24 Enclosures from Polycase

Polycase offers two different 24 x 24 enclosure models. These electronics enclosures are both members of our steel enclosure series. Every enclosure in these series is designed for extreme durability and outstanding performance in demanding environments. Our two 24 x 24 enclosure models are:
  • Polycase SA-54: The SA Series are high-performance stainless steel enclosures with a NEMA 4X rating. The SA-54 is our largest SA model—a 24 x 24 enclosure that includes a weatherproof gasket to keep your device safe from dust and water ingress. Its stainless steel construction makes it incredibly resistant to corrosion and scratching. It also includes a hinged door and built-in keyed latch system to make the enclosure as secure as it is rugged.
  • Polycase SB-54: Our SB Series models are the carbon steel cousins of the SA Series. The SB-54 is another large-sized 24 x 24 model that’s built for your most demanding enclosure applications. These steel enclosures include many of the same key features at a lower price point, including a NEMA 4X enclosure rating, weatherproof gasket, hinged cover with keyed lock and built-in bonding studs.
Both the SA Series and SB Series include all required mounting hardware, such as mounting feet and internal mounting panel and screws. Polycase SB-54 Carbon Steel 24 x 24 Enclosure
