Description
The Eaton SRN3RY12US SmartRack Industrial Enclosure is a rugged, 12U wall-mount rack solution built for demanding indoor or outdoor environments. Designed to protect critical IT and AV equipment, this steel enclosure features a NEMA 3R rating for resistance to rain, sleet, snow, and debris. Its locking, gasketed metal door ensures security from tampering and environmental exposure, while the hinged rear panel provides convenient access for installation and maintenance.
Engineered for industrial applications such as utilities, factories, transportation hubs, and security sites, the SRN3RY12US supports equipment up to 28 inches deep and a 200-lb (90.7 kg) load capacity. It includes two integrated top-mounted fans with a thermal switch that activates cooling at 86 °F (30 °C), extending equipment life and maintaining performance. Adjustable mounting rails, sealed cable entries, and a durable yellow powder-coated finish make this enclosure a reliable, space-saving solution for sensitive electronics.
