Eaton LTBK7545 Liquidtight Connector - Hazardous/Classified
Part Number: LTBK7545
Quick Summary
LTBK7545 liquidtight connector provides a robust FMC termination for hazardous-location equipment, enabling secure, compliant wiring in industrial settings. When space is tight and installation windows are short, its low-profile 45° design minimizes clearance issues and speeds assembly. This connector is rated for Hazardous/Classified Locations under NEC/CEC and UL-listed for Low Profile Liquidtight Fittings, supporting essential safety and regulatory compliance. In automation environments, that translates to faster panel builds, fewer site adjustments, and predictable safe operation. The combination of rugged malleable iron, insulated construction, and a 3/4" trade size delivers reliable performance across demanding installations while maintaining compatibility with standard FMC conduits and Eaton Crouse-Hinds ecosystems.

FAQs
LTBK7545 is designed for FMC conduit terminations in hazardous or classified locations. It carries NEC/CEC compliance and UL certification, making it suitable for Class I, Division 2 environments as well as related classifications. Its 3/4 inch trade size and 45° orientation support tight routing in control panels, process enclosures, and equipment housings, reducing space and installation time while maintaining safety margins.
The 45° connector orientation enables smoother bends and clearance around components, lowering bending radii and potential conduit damage. This translates to easier field routing, fewer installation errors, and improved reliability in compact control cabinets and machinery frames where straight fittings would require excessive panel modification.
Yes. LTBK7545 carries UL certification and NEC/CEC compliance for low-profile liquidtight fittings, with area classification suitable for hazardous locations. This affirms adherence to safety standards, supports formal inspections, and helps ensure compliance across North American automation facilities.
The rugged malleable iron, insulated body and compact form factor contribute to durable service life in harsh environments, reducing replacement frequency. Its lightweight design facilitates faster in-field installations and easier maintenance. By enabling reliable FMC terminations in hazardous areas, it supports long-term cost savings through lower labor costs and reduced downtime.
Ensure FMC conduit is 3/4 inch compatible and that mounting provides the 2.5 inch length and 2.81 inch width/height fit. Use appropriate hardware and seals per system guidelines, confirm NEC/CEC and UL certifications for the specific location, and align with Eaton Crouse-Hinds compatibility to maintain continuity with existing fittings and panels.
