    About Electrical Enclosures
    industrial info icon

    Select the right electrical enclosure for your environment and the accessories you'll need to get it mounted and connected.

    Lift-Off Cover

    Hinged Cover

    Protect your people and parts from explosive risks in areas with flammable gases, combustible dust, and ignitable fibers. These NEC-rated enclosures are often used to shield motor controls, power supplies, and wiring in plants that handle or make fuel, bulk powders, and chemicals. Plus, they lock out water to keep your electrical components dry.
    Lift-Off Cover—The removable, screw-secured cover is best for full access during setup or service, but not for frequent entry.
    Hinged Cover—The cover swings open for fast, frequent access and remains attached to prevent drops or loss.
    Aluminum—Best for housing sensors and other sensitive electronics where interference is a concern, these enclosures block wireless and radio signals. They’re also a rust-resistant alternative to stainless steel in wet areas.

    316 Stainless Steel

    Safe for use around hazardous gasses and dust, these drain vents maintain steady pressure and prevent moisture buildup from temperature changes inside enclosures. They allow air to flow through the enclosures while protecting the contents from washdowns, dirt, and weather. Install these drain vents at the lowest point on an enclosure, so moisture can drip out.
    Increased Safety—Increased-safety drain vents keep sparks, high temperatures, or current creepage inside an enclosure, so they won’t ignite flammable gasses and dust.
    Flameproof—Flameproof drain vents reduce the risk of igniting flammable gasses and dust if an explosion occurs within the enclosure.
    Glass-Filled Nylon—Glass-filled nylon drain vents are lightweight yet durable. They’re good for most areas.
    316 Stainless Steel—316 stainless steel drain vents stand up to corrosion. They’re best for areas with salt water.
