Eaton LW3400D09 Molded Case Circuit Breaker - 45 kAIC

Interchangeable thermal-magnetic trip provides precise overload protection with fast fault clearing, reducing nuisance trips and helping protect motors and circuits. This enables safer startup and consistent protection across multiple loads, which is especially valuable for OEM equipment and panel builders assembling multi-circuit enclosures. Application: control panels and motor control centers. High current capability—400 A with 690 Vac and 250 Vdc ratings and a 45 kAIC interrupt capacity at 415 Vac—ensures reliable interruption of fault currents in demanding installations. This aligns with IEC-rated protection goals and supports robust compliance for motor loads, critical drives, and distribution panels. Application: large motors, conveyors, and power distribution schemes. Three-pole LW frame with a complete breaker design simplifies upgrade paths and spare parts management. Standardization reduces inventory complexity for maintainers and OEMs while accelerating panel assembly and serviceability. Application: new equipment builds and retrofit projects across industrial automation. Line and load end caps with metric mounting hardware enable fast installation and clean, secure terminations. This minimizes wiring errors and field rework, lowering overall project risk and downtime. Application: field upgrades, service centers, and modular panel assemblies. IEC Rated with a World-class design supports global deployment with consistent performance. The combination of protection reliability and broad compatibility helps distributors and integrators streamline procurement and support across sites worldwide.
