It’s a dusty, dirty world out there. All around us, every day, billions of tiny particles of who-knows-what are circulating throughout the air—even in indoor environments that you might think would be safer. If you’re not careful, those particles can end up harming your sensitive electronic equipment. We think it’s safe to say that that’s not what you want.Enter the WA Series of dust proof enclosures. These NEMA and IP rated enclosures are specially designed to offer the perfect balance of features. From material to design to functionality, the WA Series takes electrical enclosures to a new level of efficiency with a cost-effective price point and a dust-proof IP rating.Curious about how we do it? Here are four key features that make the WA Series what it is:

1. Durable ABS Plastic Construction

Acrylonitrile butadiene styrene, better known as ABS plastic, is used to create everything from suitcases to consumer electronics. It’s also one of the best materials for indoor electrical enclosures thanks to its exceptional balance of durability and cost—which is why it’s used to make the WA Series enclosures. Major features of ABS plastic include:
  • Cost-effective to produce and work with
  • Tough and durable with exceptional impact resistance
  • High flame rating and chemical resistance
  • Resistant to oil, grease and water
These features make ABS plastic the perfect choice for the WA Series, one of our most versatile and cost-conscious waterproof and dust proof offerings.

2. NEMA and IP Rated Enclosures

NEMA and IP rating standards establish the key protective qualities that electrical enclosures need to have. Polycase WA Series Enclosures comply with NEMA 12, NEMA 13, and NEMA 4X ratings on the NEMA rating scale, and with an IP65 and IP66 rating on the IP rating scale. That means that the WA Series offers protection against not just dust and dirt, but a wide range of threats that can damage electrical equipment. They’re certified to protect against:
  • Airborne dust and dirt particles
  • Splashing water, up to and including hose directed wash-downs
  • Precipitation hazards like rain, snow and sleet
  • Ice forming on the outside of the enclosure
  • Corrosion hazards such as salt water spray
The protective qualities of a NEMA 4X enclosure or IP66 enclosure make the WA Series suitable for indoor use in everything from offices to factory floors—exactly the kind of versatility that our customers expect from Polycase. For more information about how NEMA and IP ratings can help you choose an enclosure, see our guide to NEMA enclosure ratings and our rundown of IP65 vs. IP67 enclosures.

3. UL Listed Performance

We've talked about NEMA ratings and IP ratings, the systems that establish an enclosure’s performance specs against different kinds of environmental hazards. But it’s important to know when you’re comparing options that these ratings are voluntary, and only an enclosure that’s UL Listed is truly certified to meet waterproof and dust-proof specifications.A UL listing means the product has been tested by the experts at Underwriters Laboratories, the world’s foremost experts on materials performance and safety. The Polycase WA Series has achieved a UL Listing to Type 4X, Type 12 and Type 13 specifications, which means it also meets the IP65 and IP66 rating requirement.Polycaseenclosures are tested by UL because we want our customers to know that they can trust our products to perform at the standard their applications demand. To learn more about any enclosure’s UL testing data, just find the UL file number on its product page and enter it into the UL Product iQ database. Polycase WA-24
