Description
The Eaton Tripp Lite SmartRack SRN3RY12U is a 12U NEMA 3R-rated industrial wall-mount enclosure designed to protect critical rack-mounted equipment from moisture, dust, and unauthorized access. Built from durable powder-coated steel with a bright yellow finish, it’s ideal for indoor or outdoor use in industrial, utility, or emergency-response environments.
Engineered for reliability, it supports equipment up to 23 inches deep and features a 200 lb (90.7 kg) load capacity. The lockable, gasket-sealed door provides secure protection, while dual top-mounted fans with an integrated thermal switch automatically activate above 86°F (30°C) to maintain optimal airflow.
The SRN3RY12U ships fully assembled, allowing for quick wall installation with adjustable rails and convenient cable routing through a sealed conduit cutout. Compliant with UL 508A, CSA, RoHS, REACH, and EIA/ECA-310-E standards, this rugged SmartRack enclosure ensures long-lasting performance and protection for your essential network, power, and server equipment.
