Eaton LGU4500AAG Complete LG MCCB - UL Listed

LGU4500AAG uses a complete LG frame four-pole design to handle high-current distribution in a compact form factor. This topology reduces panel complexity by consolidating protection for feeders and motors into a single device, simplifying wiring and coordination. It’s well suited for control panels and switchgear in manufacturing, process industries, and utility-style installations where reliability matters. Adjustable thermal and magnetic trip units provide precise, field-tunable protection. This flexibility minimizes nuisance trips during startup or variable load conditions while maintaining safety margins. In practice, engineers tune settings to match motor inrush and feeder characteristics, enabling consistent performance across both IEC markets and North American panels. Interrupt ratings across voltages demonstrate robust fault current handling: 200 kAIC at 240 Vac, 150 kAIC at 415 Vac and 480 Vac, and 65 kAIC at 600 Vac. That capability translates to improved system reliability and reduced risk of downstream damage during fault events. Applications include large feeders, machine lines, and critical power distribution circuits in plants. Line and load terminals plus metric mounting simplify installation and field wiring. The standardized footprint accelerates replacement, maintenance, and service center support, while compatibility with existing panel hardware reduces custom fabrication. This is especially beneficial for OEMs and integrators delivering turnkey control panels to diverse industries. UL Listed certification and HACR rating align with safety codes and motor protection practices. These attributes support compliant upgrades, selective coordination with upstream devices, and smoother approvals for equipment upgrades. The LGU4500AAG thus offers peace of mind for projects demanding both performance and regulatory readiness. Warranty and support from Eaton cover practical field life expectations: one year from installation or eighteen months from shipment, whichever comes first. This coverage helps offset initial procurement risk and complements a robust after-sales program, translating into clearer total cost of ownership and faster ROI for projects prioritizing uptime.
