Applications for Indoor Electrical Enclosures
Depending on their features, indoor electrical enclosures can fill a wide variety of roles in a facility and protect many different kinds of electrical equipment. Some of the most common applications for an indoor electrical enclosure box include:
- Handheld or desktop electronic equipment
- Thermostats, security systems and other environmental controls
- Junction boxes and outlet boxes
- Automation control units
- Circuit breakers and switchgear
Naturally, these applications require a variety of different enclosure designs and configurations to achieve the necessary protective qualities. Let’s look at a few of the key considerations.
Choosing an Indoor Enclosure
Polycase offers a wide variety of enclosures designed for indoor use. When you’re selecting an indoor enclosure, keep the following in mind:
- NEMA Rating/IP Rating: Many of our indoor electrical enclosures offer NEMA or IP-rated performance to protect your devices in harsh environments indoors. Check out our NEMA enclosure guide and IP ratings guide to learn about which ratings offer the right protection for your application.
- Material: Consider the properties of the enclosure material. Our ABS plastic enclosures are tough and cost-effective, while aluminum enclosures offer natural anti-interference properties. Meanwhile, polycarbonate, coated carbon steel and stainless steel enclosures offer extreme rugged performance and corrosion resistance.
- Built-In Features: Numerous Polycase enclosures are available with useful built-in features, from wall mount flanges to knockout plates to hinged covers. Many are offered as optional configurations, so you can choose based on the requirements of your application.
- Accessories: For many applications, enclosure accessories are a must for protecting cable pass-throughs, mounting electrical components and other functions. Polycase offers a full selection of DIN rails, cable glands and other essential accessories to equip our enclosure models. Just click the Accessories tab on each model to see available options.
- Customization: It’s easy to customize your indoor enclosures through Polycase’s in-house CNC machining and digital printing services. We offer instant quotes, fast shipping and full-service customer support that make it simple to get exactly the enclosures you need at the right price.
We invite you to browse Polycase’s extensive indoor enclosure selection here. For enclosures that can serve in outdoor applications as well, NEMA 4X Enclosure lineup is a great start, or desktop CNC enclosures for models that shine in everyday office use.
