Eaton Specification Sheet - ECLK524
Feature 1: 24-inch flexible length paired with a 30.63 inch overall length provides versatile routing through tight spaces while maintaining a strong conduit seal. Business impact: reduces the number of intermediate fittings, lowers installation time, and decreases potential leak paths in hazardous zones. Application: long runs in confined plant layouts or offshore platforms where space is at a premium and safety is non-negotiable. Feature 2: 1-1/2 inch trade size and forged brass construction offer robust mechanical strength and corrosion resistance. Business impact: longer service life and lower maintenance costs in aggressive environments, improving total cost of ownership. Application: standard conduit systems in chemical processing and marine facilities. Feature 3: Male on one end, female on the other enables quick, secure assembly without specialized adapters. Business impact: faster field completion, reduced labor hours, and easier replacement. Application: rapid splicing during outages and routine maintenance. Feature 4: NEC/CEC compliance with hazardous-location ratings (Class I, Division 1; Class II, Division 1; Class III) plus UL certification. Business impact: simplifies regulatory approvals and reduces audit findings, elevating project confidence. Application: installations in classified locations requiring proven explosion-proof performance. Feature 5: Area-classified and standard-compliant fittings ensure consistent performance across industrial environments. Business impact: predictable performance, consistent safety margins, and easier supplier qualification. Application: cross-site deployments in refineries, petrochemicals, and marine environments. Insight: The ECLK524 is designed for reliability under demanding conditions, balancing rugged hardware with install efficiency. It supports updated electrical codes and industry practices, helping teams meet tight project schedules and regulatory demands without compromising safety.
