Overview

The nVent GL66 Series Medium Wall-Mount Enclosure (SKU: M1200800400G) is a 1200x800x400mm steel enclosure designed for industrial environments requiring IP66 and Type 4/12 protection. Constructed from 1.5mm (16 gauge) steel with a light-gray RAL 7035 textured polyester powder-coated finish, this enclosure resists corrosion, UV degradation, and chemical exposure. Its seamless foam-in-place gasket ensures IP66 compliance, protecting against dust and water jets, while the external 90-degree body flange channels liquids away from the interior. The enclosure features a corner-formed door with removable hinges, high-torque threadless studs, and a three-point latching system for enhanced security. A full-height galvanized steel back panel is included for component mounting, with grounding studs on the body and bonding provisions on the door for electrical safety. Pre-cut gland plate openings in the enclosure bottom simplify cable entry, and the hardware kit includes grounding and sealing components. Ideal for manufacturing plants, utility substations, and telecommunications facilities, the GL66 Series supports internal mounting flexibility with optional accessories like gland plates, back panels, and accessory rails.
