For use in hazardous locations, these enclosures are rated NEMA 7 and 9 and meet UL Class I, Divisions 1 and 2, Groups B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2. They are also rated NEMA 4 for protection from dirt and washdowns.

Panels are for mounting components inside enclosures.

These enclosures reduce electromagnetic interference (EMI) and radio frequency interference (RFI), which can cause electrical problems like flickering monitors, interrupted data signals, and unwanted radio noise. Use them near motors, generators, and other equipment that produces EMI or RFI. Enclosures protect the parts inside and also keep EMI/RFI generated within the enclosure from getting out.

To install parts inside the enclosure, screw a DIN rail or panel on to the internal mounting bosses, or mount components directly to the bosses using self-tapping screws. Use the outside mounting holes to attach the enclosure to a wall or surface. For more mounting flexibility, screw on wall-mount brackets where you need them.

Aluminum enclosures stop medium-range frequency interference in most applications. They have two gaskets—a woven steel gasket joins the two sides of the enclosure for continuous EMI/RFI shielding, and a silicone rubber gasket seals the enclosure to protect your equipment from wet, oily, and corrosive environments. Enclosures that meet IP65 protect the contents from washdowns, dust, and dirt. Enclosures that meet IP67 are submersible in one meter of water for up to 30 minutes and protect the contents from dust and dirt.

Interference reduction at frequency, also known as attenuation, is how much EMI/RFI the enclosure blocks.

Made of aluminum, these enclosures resist corrosion from rain, sleet, and snow. While not as corrosion resistant as stainless steel, aluminum is lighter for better mobility, and also easier to machine for custom mounting. With an overhanging top for coverage from above, these enclosures are rated NEMA 3R for protection from dirt, falling liquids, and light splashing. A bonding stud on the door maintains electric potential for connected equipment and also prevents static sparking that could damage components. To draw away static and protect from fire and shocks caused by short circuiting, connect these enclosures to a grounding path with the included grounding stud.
