Eaton Specification Sheet - EBMX1B-W040
Copper-free aluminum enclosure and clamped cover reduce corrosion risk and weight, accelerating install and service while improving lifecycle costs in coastal or chemically harsh environments. Hazardous locations certification, including Class I Division 1 and Zone 1 with NEC/CEC adherence, supports regulatory compliance and risk reduction in oil, gas, and chemical processing facilities. A 600 VAC rating and 40 AIC interrupt capability deliver fast, reliable disconnection for feeders and critical circuits, minimizing arc exposure and shutdown time. Size 1 enclosure dimensions (22.11 in L x 12.86 in H x 15.98 in W) enable straightforward retrofits and panel compatibility, reducing engineering time and field modification. NEMA ratings of 3R and 4X provide environmental protection for outdoor and corrosive environments, expanding placement options. Access to SP3D design packages, catalogs, and IF 1149 installation instructions shortens design cycles and simplifies procurement.
