Eaton Specification Sheet - EBMX2B-W175
Copper-free aluminum enclosure reduces weight and corrosion exposure, enabling longer service life in harsh environments and lowering maintenance costs in chemical, mining, or outdoor installations. Feature → Business Impact → Application: design resilience and reduced replacement cycles translate to lower total cost of ownership for hazardous-location projects such as oil and gas processing plants. Three-pole configuration with 600 Vac and 175 AIC interrupt rating provides robust fault clearance, improving uptime and protecting motors and drives in large process lines. This aligns with lifecycle planning and safety programs in industrial facilities where code-compliant protection is non-negotiable. The clamped enclosure cover simplifies installation and field maintenance, accelerating commissioning and reducing on-site labor time for multi-panel deployments. Compatibility with standard EBMXB accessories and installation kits supports fast retrofits and scalable expansion in growing facilities. Industry-specific context: electricians and engineers gain predictable performance, improving project timelines and regulatory adherence.
