Eaton LGE3400FAWCA2S6X1Y17 Molded Case Circuit Breaker - 65 kAIC at 240 Vac

The LG-frame, three-pole LGE3400FAWCA2S6X1Y17 delivers 400 A at 600 Vac with a T185 trip profile, which translates to precise overload and short-circuit protection for demanding electrical systems. This feature directly improves system reliability and reduces unplanned downtime in industrial automation and control panels, enabling tighter safety margins and easier coordination with upstream protection devices. The fixed thermal and adjustable magnetic trip provide selective coordination, minimizing nuisance trips and protecting critical loads, which lowers maintenance costs and extends equipment life in motor and drive applications. The device ships with a 2A-2B rear auxiliary switch and a 24 Vdc shunt trip, enabling remote control and condition-based protection for safety interlocks and emergency shutdown scenarios. Copper terminals and the option for line or load terminals offer installation flexibility, reducing wiring time and improving field serviceability. With a compact 5.48 in footprint and a 16 lb weight, the Series G MCCB supports dense panel layouts and straightforward retrofit projects while maintaining compliance with core protection standards. The 65 kAIC short-circuit rating at 240 Vac and 35 kAIC at higher voltages provides robust fault tolerance for medium-voltage distribution, aligning with common industry reliability targets and enabling scalable protection strategy in evolving automation environments.
