Eaton Specification Sheet - LTB300
Conduit type FMC provides a compatible, weather-resistant seal that improves moisture protection and reduces ingress risk, delivering a tangible efficiency gain during installation in demanding environments. This straight connector design enables quicker alignment along runs, decreasing installation time and minimizing field errors, especially in tight control panels or crowded conduit trenches. The malleable iron body offers rugged durability and impact resistance, ensuring long service life in harsh facilities such as chemical plants or mining operations. Insulated construction shields conductors from moisture and contaminants, lowering insulation wear and potential short circuits, which translates to lower maintenance costs and fewer unplanned outages. The 3-inch trade size matches common FMC configurations, reducing the need for adapters and inventory complexity for maintenance teams. Certifications including NEC/CEC compliance and Hazardous/Classified Location ratings provide regulatory confidence for industrial projects and customer audits. The compact footprint (3.63 in length, 4.19 in height and width) and 4.56 lb weight support stable mounting in crowded enclosures, while available CAD drawings and spec sheets streamline engineering validation and procurement workflows.
