Copper-free aluminum enclosure delivers corrosion resistance and lighter weight, reducing shipping and installation effort while maintaining durable protection in harsh environments. This translates to lower total cost of ownership and faster commissioning on site, especially in coastal or chemically aggressive facilities. The 20A, 125 Vac rating with a broad 50-400 Hz frequency capability supports a wide range of equipment, improving compatibility with existing plant controls and minimizing rework during system upgrades. The two-gang, 3/4 inch trade size and double cover configuration simplify wiring layouts and enclosure access, enabling faster terminal junctions and safer maintenance in tight spaces. Group B rating and dead-end style reduce ignition risk and surface heat, enhancing overall safety in classified locations. NEMA 3, 7, 9, 12 protection and NEC/CEC conformity provide a clear path to compliance across North America, aiding procurement and installation planning. Ark-Gard ENR Value integration supports standardized accessory compatibility, improving spare parts planning and ongoing serviceability for hazardous-area programs.
