Based in Greencastle, Pennsylvania, our company creates custom electrical enclosures for clients throughout the United States. 

We understand that you have unique industrial enclosure needs. That’s why we offer a range of custom enclosure options, including a disconnect switch, to ensure you have the specific features required for your applications. 

Our Electrical Enclosures With Disconnect Switches

At APX Enclosures, our entire inventory of electrical enclosures is certified by the National Electrical Manufacturers Association (NEMA) for reliability and safety. They are suitable for indoor and outdoor use. Whether you need electrical enclosures for the security, transportation, telecommunications or industrial productions industry, our products provide reliable protection from dirt, dust, heat, rain, sleet and ice.

Whatever option you choose, you can trust that your enclosure has been crafted with quality materials and attention to detail. We have electrical testing capabilities such as HIPOT testing, continuity and ground bonding to ensure each enclosure meets these guidelines and standards. We can also prewire the electrical enclosure for you, making installation quick and easy.


Typically used for wiring boxes for communications and utilities, the NEMA 3R offers comprehensive protection against the elements and solid foreign objects. Your critical components will be kept safe, and you can feel confident your personnel will be protected from any hazardous parts. We carry many styles such as double door, ecoline, quad door and rack mount that can all be customized with a disconnect switch.


The NEMA 4X offers protection against fine-textured materials like windblown dust. Commonly used in environments with food products, this electrical enclosure offers protection from water and even salt spray. Choose from a variety of designs and structural components as well as configurations ranging from a rear door to a rack mount. With the addition of a disconnect switch, you’ll be able to cut the power whenever necessary.
