FAQs

The LGE3400AAG uses metric mounting hardware and LG frame dimensions suitable for standard panel cutouts. Ensure line and load terminals are correctly oriented, secure with provided hardware, and verify clearances for hot and neutral conductors. Follow the 50/60 Hz operating range and torque specifications from Eaton’s installation guidelines to ensure proper trip coordination and safe enclosure integration.
This breaker features adjustable thermal and magnetic trip, enabling precise protection matching load profiles and inrush characteristics. In practice, this reduces nuisance trips while maintaining fast response to overloads. Use the adjustable settings to coordinate with downstream devices and ensure selectivity across multi-breaker feeders in industrial panels.
Yes. The unit is rated for 400 A with three poles and LG frame construction, designed for main protection in industrial power distributions. It provides high interrupt ratings (65 kAIC at 240 Vac, 35 kAIC at 480 Vac, 18 kAIC at 600 Vac) and is compatible with metric mounting for streamlined installation in control panels and heavy machinery.
The LGE3400AAG carries UL Listed certification, supporting compliance in many markets. The catalog notes also indicate HACR rating, which is beneficial for motor protection in HVAC and similar load environments. This combination supports regulatory compliance and reliable motor protection in IEC markets.
With adjustable trip settings and robust 400 A protection, maintenance focuses on periodic verification of trip settings and terminal integrity. The UL Listing and HACR rating help ensure ongoing compliance and reduced downtime. The unit's compatibility with metric mounting and line/load terminals supports faster panel upgrades, potentially lowering total cost of ownership over multiple projects.
