Description
The Eaton Tripp Lite SmartRack SRN3RR12U is a rugged 12U wall-mount industrial enclosure engineered to protect critical rack-mount equipment in demanding indoor or outdoor environments. Built from fully welded, powder-coated steel, this NEMA 3R enclosure safeguards network, power, and security equipment from rain, sleet, snow, dust, and tampering.
Designed for space-constrained installations, the enclosure supports standard 19-inch rack equipment up to 23 inches deep, making it ideal for switches, patch panels, PDUs, UPS systems, and servers. A locking, gasket-sealed door prevents unauthorized access while allowing convenient service access during installation and maintenance.
Integrated top-mounted fans with a thermal switch automatically activate to maintain proper airflow and help extend equipment life. The SRN3RR12U ships fully assembled and mounts securely to the wall using customer-supplied hardware, making it a dependable solution for industrial, utility, transportation, security, and first-responder applications.
