It's been raining here a lot recently in Indiana, and it's got me thinking about outdoor use of our products. You can't use most normal relays outside as they are only NEMA 1 rated. NEMA 1 is a rating defined by the National Electronics Manufacturers Association. In a nutshell (enclosure pun intended), NEMA 1 means that the device is protected from falling dirt and debris, and you are protected from the potentially harmful (voltage pun intended) electronics inside. However, NEMA 1 enclosures don't have any protection against the weather. Water can usually get inside a NEMA 1 with ease. If it does, water will cause damage to the electronics inside and possibly even to devices connected to it.
Luckily there is another type NEMA enclosure we offer: NEMA 4/4X. Unlike NEMA 1 enclosures, NEMA 4/4X enclosures are rated for outdoor use. They offer protection against rain, snow, ice, corrosion, and have the same protection against dirt and fingers that NEMA 1 enclosures have. We have a large selection of products with NEMA 4/4X rated housings, including the classic RIBU1C in the form of model RIBU1C-N4. We also have other enclosures that are NEMA 4/4X rated, so you can protect whichever device you have. Just look for the "-N4" at the end of a product name.
NEMA 4/4X Enclosures for Outdoor Automation
When your building automation project extends outdoors, your equipment needs to handle more than just dust—it needs to stand up to rain, snow, and corrosion. That’s exactly why we offer many of our RIB relay products in NEMA 4/4X enclosures. These housings allow you to take reliable relay control to rooftops, outdoor lighting poles, and pump houses while keeping the same straightforward wiring and dependable performance you trust indoors.
From the classic RIBU1C-N4 to other “-N4” models in our lineup, these RIB relay products in NEMA 4/4X enclosures make expanding your building automation system outdoors simple and consistent. You get the weather resistance needed for tough environments while still enjoying the ease of installation that RIB relays are known for. It’s an easy way to keep your controls protected while ensuring your automation system can extend where your facility needs it most.
