Eaton LGU3500FAG - 500 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton LGU3500FAG—a robust 3-pole molded case circuit breaker designed to guard your panelboards and load centers with reliable overcurrent and short-circuit protection. Rated at 500 A and 600 V, this unit is a strong choice for safeguarding large feeders and critical branch circuits in residential, commercial, and light industrial applications. Available through AmpState, it pairs Eaton’s trusted engineering with a compact, space-conscious footprint.

Why this breaker stands out

• Compact molded case design maximizes panel space, letting you protect more circuits without crowding the enclosure.
• Thermal-magnetic trip unit delivers stable, repeatable protection across varying loads and temperatures, with fast response to short-circuit conditions to minimize damage and downtime.
• 3-pole configuration provides synchronized protection for three-phase systems, helping maintain phase balance and equipment longevity—ideal for motors, compressors, and HVAC equipment.
• High amperage and voltage ratings—500 A continuous current at up to 600 V—making it suitable for main feeders and substantial branch circuits in building infrastructure.
• OEM-compatible design ensures smooth integration with matching Eaton OEM load centers and panelboards, supporting coordinated protection and straightforward installations.
• Versatility across environments designed to perform reliably in residential basements, commercial electrical rooms, and light industrial settings where dependable protection is essential.

Real-world use cases

• Feeder protection for a commercial subpanel feeding office suites, lighting, and outlets with consistent overload protection and short-circuit interruption.
• Main breaker or feeder role in large residential or multi-tenant buildings where robust 500 A protection helps manage high electrical demand.
• Protection for motors, pumps, or HVAC equipment in light industrial spaces where three-phase integrity and rapid fault clearing are critical.

Practical considerations for installation and selection

When choosing the LGU3500FAG, verify panelboard compatibility with Eaton’s documented load centers to ensure proper bus bar fit and electrical coordination. The 3-pole design is ideal for three-phase circuits, so plan your wiring to maintain phase balance and minimize nuisance trips. Use appropriate conductor sizing and follow standard torque specifications for lug connections to maintain secure, reliable performance over time. If you’re upgrading or retrofitting a panel, this unit’s OEM compatibility streamlines replacement and reduces the risk of mismatched protection.
