Eaton Specification Sheet - EFDC31106
Explosion-proof enclosure construction provides robust protection in hazardous locations, reducing ignition risks in Class I and II environments. Business impact: enhanced safety, stronger regulatory compliance, and lower incident-driven downtime. Application: ideal for chemical processing, mining, and other high-risk industrial settings where reliable protection is essential. The 30 A amperage rating and 1" trade size align with standard control panels, enabling faster wiring and streamlined panel layouts for single-pole, through-feed configurations. This simplifies installation and reduces field labor costs during commissioning and future expansions. Feraloy iron alloy enclosure material delivers superior hardness and corrosion resistance, extending service life and lowering maintenance costs in harsh environments. The bolted/ground joint enclosure further minimizes leak paths and ensures a consistent, sealed installation in challenging conditions. Certifications and standards, including NEC/CEC compliance and NEMA ratings 3, 7, 9, 12, support ease of audits and long-term regulatory alignment. Square D compatibility and through-feed design enable smooth integration with existing panels and drop-in replacement in compatible EFDC assemblies. Industry-standard dimensions and mounting patterns reduce design-time and accelerate project delivery. By addressing common objections—such as cost and install complexity—the EFDC31106 delivers a compelling return on investment through lower replacement frequency, reduced downtime, and predictable performance in hazardous locations.
