Eaton LGH3400FAWC Molded Case Circuit Breaker - UL Listed

The 400 A amperage rating delivers robust protection for main feeders and critical loads, reducing the risk of nuisance trips during startup and overloads and boosting overall plant uptime. This translates to lower maintenance costs and fewer production interruptions in continuous process environments, especially for machining centers and packaging lines that demand steady power. With fixed thermal and adjustable magnetic trip, coordination is improved between upstream and downstream protection devices, enabling selective tripping and minimized collateral outages during faults. This is particularly valuable in multi-zone control panels where motor drives and loads with varying inrush must operate safely together. The LG frame and Series G design provide compact footprint without compromising performance, simplifying panel layouts and component sourcing for OEMs and aftermarket integrators. Compatibility with standard MCCB accessories improves installation speed and reduces engineering time for new builds.The unit supports 50 to 60 Hz operation and remains 100% rated, ensuring consistent performance across global facilities and varying supply conditions. Without terminals reduces wiring complexity and saves panel space, enabling cleaner, more reliable wiring harnesses in control panels. These attributes align with modern factory automation trends toward modular, serviceable protections that can be swapped with minimal downtime. For OEMs and integrators, this translates into faster project commissioning and easier spare-part inventory management, improving total cost of ownership across the equipment lifecycle.
