90° angle design enables tight mounting in crowded panels. This geometry reduces enclosure footprint and streamlines cable routing for FMC connectors, accelerating panel wiring in motion-control and automation cabinets. Zinc die cast housing provides rugged durability. The metal body offers excellent impact resistance and corrosion protection, extending service life in busy factories and harsh environments while lowering maintenance costs. Non-insulated construction lowers material cost and weight where internal insulation is unnecessary. This choice simplifies installation in control enclosures and reduces part count without compromising conductive performance. 3/8 inch trade size matches conventional FMC fittings. Standard sizing minimizes the need for adapters and expedites procurement, improving schedule certainty on capital automation projects. FMC compatibility enables straightforward field terminations with existing conduit runs. It supports quick, code-compliant connections in confined spaces, boosting installation safety and reliability. NEC/CEC compliance and hazardous location ratings provide regulatory assurance. Class I Division 2, Class II Division 1 and 2, and Class III designations help verify suitability for chemical plants, refineries, and other hazardous areas. UL certification documentation and Eaton catalog data are readily accessible for audits. This transparency reduces supplier risk and streamlines qualification during procurement cycles and inspections. Compatibility within the Eaton Crouse-Hinds zinc die cast liquidtight family simplifies stocking and spares planning. Designers can standardize on LT3890DC and related fittings to optimize maintenance and training. Field service teams appreciate predictable performance metrics and long-term availability. The LT3890DC’s combination of rugged build, standardized sizing, and documented compliance supports lower total cost of ownership in automation deployments.

FAQs
When wiring LT3890DC with FMC conduit, ensure proper alignment of the 90° elbow to minimize stress on the conduit and strain relief. Use manufacturer-recommended sealing practices and verify a secure engagement with the FMC sleeve. Plan for tight spaces by confirming clearance around the connector and avoiding sharp bends that could affect conduit integrity and electrical performance.
LT3890DC is designed for hazardous locations and carries NEC/CEC compliance with Class I Division 2 ratings. In these environments, the zinc die cast body provides robust mechanical protection, while the non-insulated design supports clean, straightforward terminations. Always couple with compliant enclosures and follow installation practices that preserve safety classifications during commissioning.
Yes, LT3890DC uses a 3/8 inch trade size that matches common FMC fittings and supports outdoor enclosure use when paired with appropriate enclosures and environmental protections. The zinc die cast construction offers corrosion resistance, aiding durability in challenging outdoor settings. Ensure enclosure seals and mounting methods maintain the integrity of the hazardous-location rating.
LT3890DC carries NEC/CEC compliance with hazardous-location ratings, including Class I Division 2, Class II Division 1 and 2, and Class III. It also aligns with UL certification expectations for metallic liquidtight fittings. These certifications support regulatory conformity, safe installation practices, and smoother procurement and qualification processes for control panels and automation equipment.
The LT3890DC offers lifecycle benefits through durable zinc die cast construction that resists impact and corrosion, reducing maintenance and replacement costs. Its standardized 3/8 inch size and 90° geometry speed installation, lower spare part variety, and reliable NEC/CEC compliance contribute to shorter downtime, faster commissioning, and predictable total cost of ownership on automated production lines.
