Tripp Lite SmartRack Industrial Enclosure, NEMA 3R, Wall Mount, Metal, Locking, Hinged Back, Fan With Thermal Switch, 28 in. Depth, 12U, Yellow

The Tripp Lite SRN3RY12US is a wall-mounted industrial enclosure that provides 12U of secure rack space for equipment measuring up to 28 inches deep. It is a practical solution for sites where dust, moisture, and fluctuating temperatures could damage networking or control hardware.

A steel housing with a powder-coated finish carries a NEMA 3R rating, protecting the contents from rain, sleet, snow, dirt, and ice buildup. The door locks with the included keys, and the fully welded body limits tampering and vibration. A hinged back panel swings open, allowing technicians to reach cables and components without detaching the cabinet from the wall.

Two fans sit on the top panel and switch on automatically when the internal temperature rises above 86°F. This thermal response helps keep switches, routers, and automation controls running reliably during hot shifts or when the enclosure is mounted in direct sunlight.

Adjustable mounting rails accommodate equipment of varying depths, while the compact footprint keeps walkways clear. The cabinet is well suited to factories, power plants, construction sites, or any setting that needs organized, protected electronics in limited space.

The enclosure ships ready for installation, includes all necessary mounting hardware, and is backed by a five-year limited warranty from Tripp Lite.
