Eaton LTB400 Liquidator Connector - Hazardous/Classified
Part Number: LTB400
Quick Summary
The Eaton LTB400 Liquidator Connector is a rugged liquidtight FMC fitting designed for hazardous-location enclosures. In busy facilities, moisture ingress, dust, and vibration threaten seal integrity and uptime; this connector helps reduce maintenance cycles and retrofit risk by delivering a robust, pre-insulated seal. It carries NEC/CEC compliance and is rated for Class I, Division 2; Class II, Division 1 and 2; and Class III locations, supporting safe operation across a wide range of chemical and electrical environments. By combining a 4 inch trade size, a malleable iron body, and an insulated design, it simplifies field termination and reduces panel footprint. For engineers and procurement teams, this translates to faster installs, fewer spare parts, and clear regulatory alignment.

FAQs
Yes. The LTB400 is a straight FMC liquidtight connector designed for hazardous locations and is rated for Class I Division 2, with additional support for Class II and III locations. It provides a secure, vibration-resistant seal suitable for control panels and field terminations in harsh environments.
The LTB400 provides a 4 inch trade size, with a body height and width of 5.75 inches each, and a product length/depth of 4 inches. It weighs 7.9 pounds and is made from malleable iron with an insulated construction to withstand moisture, dust, and impact in demanding settings.
Absolutely. Its hazardous-location ratings (NEC/CEC) and Class I Division 2, Class II/III classifications make it well-suited for control panels, junctions, and equipment enclosures exposed to hazardous chemicals, dust, and moisture, while maintaining robust seals and easy field termination.
The LTB400 supports NEC/CEC standards and NEC hazardous ratings for several divisions. Documentation and certifications are available through UL and Eaton sources, including the NEC/CEC compliance sheets and UL certification references found in Eaton’s product literature and UL databases.
The LTB400’s insulated, malleable-iron build, straight FMC configuration, and 4 inch size streamline installation, reduce maintenance intervals, and improve regulatory compliance. Its rugged construction lowers field repair costs and speeds up panel assemblies in hazardous-location projects, delivering tangible lifecycle savings.
