Description
The Eaton SRN3RR12US SmartRack Industrial Enclosure provides rugged, weather-resistant protection for mission-critical rack equipment in demanding environments. With a 12U capacity and 28-inch depth, it securely houses 19-inch rackmount devices such as switches, servers, UPS systems, and patch panels.
Built from powder-coated steel and rated NEMA 3R, this enclosure safeguards against rain, sleet, snow, dirt, and external ice formation—making it ideal for industrial, utility, and first-responder applications. Its locking hinged design enables quick rear access while maintaining security, and dual top-mounted fans with a thermal switch ensure optimal cooling when internal temperatures exceed 86°F (30°C).
Designed for easy installation, the SRN3RR12US comes fully assembled, includes adjustable front and rear mounting rails, and supports up to 200 lbs (91 kg) of equipment. Perfect for indoor or outdoor use, it ensures reliable protection, airflow, and cable organization in challenging operational conditions.
