IP Rated Enclosures

IP enclosures provide protection for electrical and electronic devices in environments prone to dust, dirt and moisture. Designed for indoor or outdoor use, Polycase’s IP rated enclosures and electrical boxes include a waterproof gasket between the base and cover. Polycase IP Ratings are based on the NEMA 250 to IEC 60529 conversion table published by NEMA.org. We have durable enclosure options meeting IP65, IP66, IP67 and IP68 ratings, making them ideal for use in virtually any industry or application. We also offer a full selection of NEMA enclosures.

IP rated housings are available in a variety of sizes, styles and materials, making it easy to find a solution to fit your needs. Looking for more information on IP rated enclosures? Read more below and learn the basics.

What Are IP Ratings?

The ingress protection rating scale is the most widely used system worldwide for rating the protective qualities of electrical enclosures. As its name suggests, it measures the degree of protection an enclosure provides to electrical equipment against both the ingress of water and the ingress of solid particles such as dust.

Ingress protection ratings are based on the International Electrical Code standard IEC 60529. For this reason, you’ll find the IP enclosure code used both in North America and in global markets such as the European Union and East Asia. It provides a unified standard that applies across many different enclosure types and helps device designers ensure that they’re using enclosures with the right level of protection.

IP ratings can be converted into the NEMA ratings more common in North America, but since NEMA ratings include various factors that IP ratings don’t, the reverse is not always possible. (For example, a NEMA 4X rating can’t be properly converted into an IP rating since it includes corrosion resistance.) See our IP to NEMA conversion guide for more information.

Reading an IP Rating

Interpreting IP ratings is simple once you understand the two-digit system that they use. The first digit measures solid ingress protection on an ascending scale of 1 to 6, while the second digit measures water ingress protection on an ascending scale of 1 to 8.

Let’s use an IP66 enclosure as an example. The first digit, 6, denotes a completely dust-tight enclosure that’s completely sealed against solid foreign objects such as dust, lint and shavings, as well as against accidental contact. The second digit, 6, denotes a watertight enclosure that’s resistant to rain, splashing, pressurized water jets and most other types of water ingress. (However, it’s not rated for complete submersion. You’ll need to step up to an IP67 or IP68 enclosure for that.)

Choosing an IP Rated Enclosure from Polycase

The first step in selecting an IP enclosure is always to consider the needs of the electrical components and devices that the enclosure will protect. See our IP ratings guide and our enclosure materials guide to compare choices and discover which is right for your application.
