Manufacturer
Eaton Crouse-Hinds
Part number
LTB250DC

Quick Summary

LTB250DC is a rugged liquidtight connector used for hazardous-location conduit terminations in industrial equipment. In many plants, installers confront restricted spaces, chemical exposure, and the pressure to meet strict electrical codes; this connector helps address those challenges with a proven, durable design. It carries NEC/CEC approvals for Hazardous/Classified Locations, including Class I Division 2 and Class II/III ratings, providing verifiable safety compliance for critical systems. The FMC compatibility, insulated zinc die-cast housing, and 2-1/2 inch trade size support fast, reliable terminations, while reducing maintenance needs. By aligning with standard FMC fittings and enclosure layouts, it enables streamlined procurement and faster commissioning across manufacturing, processing, and energy applications.

Zinc die-cast, insulated housing defines the LTB250DC as a rugged yet compact solution for FMC conduit terminations. The straight configuration simplifies field routing, while the 2-1/2 inch trade size covers a common industrial feeder and machine-wiring footprint. The combination of corrosion-resistant finish and robust mechanical engagement translates to fewer service calls and a lower likelihood of moisture ingress in demanding environments. NEC/CEC compliance with Hazardous/Classified Locations approvals, including Class I Division 2 and Class II/III ratings, provides documented safety and regulatory alignment. This reduces the engineering burden during audits and simplifies change management in plants subject to multiple jurisdictional standards. The connector's rated environmental performance supports continuous operation in dusty, wet, or chemical-exposure zones, helping you avoid costly rewrites of electrical drawings. Designed for compatibility with FMC conduit systems, the LTB250DC reduces parts count and assembly time. Its straight design eliminates elbow flexibility issues in tight spaces, and the zinc-die-cast body provides machinable surfaces for strain relief and grounding. Field technicians benefit from straightforward torque ranges, reliable sealing, and fewer misfits, which translates into faster commissioning and less rework. Documentation and certifications are readily accessible, including UL-based Canadian certifications and Eaton specification sheets to guide procurement and maintenance programs. The LTB250DC's durable construction supports long service life in harsh environments, offering a lower total cost of ownership through reduced replacements, less downtime, and improved system reliability.

FAQs

Installation steps start with verifying conduit compatibility and correct gasket seating, then aligning the straight connector with the FMC sleeve. Secure with manufacturer-recommended torque to ensure a water-tight seal, confirm insulation integrity, and verify Class I Division 2 or relevant ratings during commissioning. Use appropriate sealing compounds or gaskets per NEC/CEC guidelines and document the installation for audit trails.
LTB250DC carries NEC/CEC compliance for Hazardous/Classified Locations, including Class I Division 2, Class II Division 1 and 2, and Class III ratings. This enables safe operation in hazardous environments and supports regulatory audits. It is designed for FMC conduit, insulated construction, and a 2-1/2 inch trade size to meet common industrial wiring standards.
Yes. The LTB250DC is expressly rated for Class I Division 2 locations, along with Class II and III ratings, under NEC/CEC standards. This makes it appropriate for areas with flammable substances or hazardous atmospheres, enabling compliant terminations in industrial control panels, machinery enclosures, and process equipment wiring.
Beyond NEC/CEC, the LTB250DC benefits from certification materials such as Canadian certification references from UL and Eaton specification sheets. These resources support cross-border procurement and compliance verification, helping maintain a consistent safety and performance standard across regions.
The zinc die-cast, insulated construction provides corrosion resistance and durable sealing, reducing maintenance cycles and part replacements. The connector’s robust design supports longer service life in dusty, wet, and chemically aggressive environments, delivering lower total cost of ownership through reduced downtime and faster, complaint-driven servicing.
