Overview

The nVent A36R2412 is a 36x24x12 inch Type 3R screw-cover enclosure constructed from 16-gauge galvanized steel with an ANSI 61 gray polyester powder paint finish. Designed for outdoor industrial applications, this enclosure protects controls, wiring, and junction points from rain, sleet, snow, and dripping water. The screw-cover design acts as a drip shield with a 3/4-inch overhang, preventing water ingress without gasketing. It meets UL 50, 50E, cUL, NEMA/EEMAC Type 3R, and IEC 60529 IP32 standards. Key features include seam-free sides, front, and back, embossed screw locations, and embossed mounting holes on the back for direct mounting. Pre-punched knockouts in the bottom facilitate conduit entry. Optional mounting brackets (included) provide a 1-inch clearance off the surface for protection against pooling water. The enclosure is suitable for rooftop or pad-mounted equipment where protection from precipitation is essential. This product is manufactured in the US and distributed by Gross Automation.
