Overview

The nVent MAS0304021R5 is a single-door mild steel enclosure designed for wall mounting in industrial environments. Measuring 300x400x210mm, this enclosure provides robust protection for electrical and electronic components with an IP66 rating, preventing dust ingress and powerful water jets. The folded and seam-welded body features four 8.5mm wall-fixing holes with pressed-out depressions for air circulation. The rear gland plate opening simplifies cabling onto the included mounting plate, which is marked vertically at 10mm intervals for precise equipment positioning. The mounting plate is fixed to M8 press-welded studs and includes top/bottom holes for cable fixing. Constructed from 1.4mm mild steel (body) and 2mm galvanized steel (mounting plate), the enclosure resists corrosion with a RAL 7035 structured powder coating. The door features concealed removable hinges with captive pins, 130° opening, and an injected one-piece polyurethane gasket for sealing. A customized double-bit 3mm lock with anti-vibration mechanism ensures security. Ideal for motor control, automation systems, and electrical distribution in manufacturing, food processing, water treatment, and infrastructure projects.
