Interlocked receptacle with built-in circuit breaker provides a clear lockout status, preventing energization until the interlock is reset. Business impact: safer startup, reduced human error, and lower incident risk in hazardous environments. Application: ideal for oil, gas, chemical processing, and mining facilities where control circuits must be safeguarded against accidental energization. Copper-free aluminum enclosure paired with brass contact material offers corrosion resistance and reliable conductivity. Business impact: longer service life, lower maintenance, and reduced replacement costs in aggressive atmospheres. Application: outdoor walkways, washdown areas, and chemically exposed enclosures. Spring door receptacle design provides dust ignition protection and quick field servicing. Business impact: faster maintenance cycles and consistent dust-exclusion performance, lowering ignition sources. Application: enclosed control panels and hazardous-location enclosures. Electrical ratings of 30A, 600 VAC in a three-wire, three-pole configuration ensure compatibility with typical industrial controls. Business impact: standardized sizing reduces engineering time and enables seamless integration with existing Eaton components and IF 1181 instructions. Application: new builds or refurbishments in hazardous locations. Compliance and certifications support NEC/CEC alignment, Hazardous/Classified Locations area classification, and NEMA ratings 3, 9, 12. Business impact: regulatory confidence, simplified procurement, and risk mitigation. Application: regulated facilities seeking robust protection for interlocked receptacles.
