Eaton LGE340032W - 400 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton LGE340032W is a high-capacity, 3-pole bolt-on molded case circuit breaker designed to guard your electrical distribution with precision. Rated at 400 A and 600 V, it fits seamlessly into panelboards and load centers, delivering dependable branch-circuit overcurrent and short-circuit protection in residential, commercial, and light industrial environments.

Why the LGE340032W stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, reducing the risk of loose connections in installations subject to movement or vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection. The thermal element responds to prolonged overloads, while the magnetic mechanism handles instantaneous short circuits for faster clearance and minimized equipment damage.
• OEM-compatible design is engineered to pair with matching OEM load centers and panelboards, helping you achieve a clean, plug‑and‑play fit without aftermarket adjustments.
• Versatile for multiple sectors ideal for service upgrades, feeders, and main distribution in homes, small to medium commercial spaces, and light industrial setups.

How this breaker improves your electrical system

Choosing the LGE340032W means selecting a breaker engineered for longevity and predictability. The bolt-on design reduces connection variability, while the dual-mode trip (thermal and magnetic) provides both slow-response protection for sustained overloads and immediate action for short circuits. This combination helps protect wiring insulation, downstream devices, and your overall distribution system from damage and nuisance trips.

Who should consider it

• Licensed electricians undertaking panelboard upgrades or new installations that require a robust 400 A, 3-pole solution.
• Facility managers looking to standardize protective devices across multiple panels while preserving OEM compatibility.
• contractors handling heavy-load, three-phase applications in commercial or light industrial environments.

Practical tips and considerations

• Ensure the panelboard or load center is designed to accept bolt-on molded case breakers of this rating and configuration for a trouble-free installation.
• Plan for thermal management in environments with elevated ambient temperatures; a properly rated thermal-magnetic breaker helps prevent nuisance trips during peak loads.
• Maintain a spare LGE340032W on hand for quick replacements in critical service panels to minimize downtime.
