Eaton Lge3630Nnwc - 630 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Eaton Lge3630Nnwc 630A, 600V, 3-pole molded-case circuit breaker is designed to deliver dependable branch-circuit overcurrent and short-circuit protection right where you need it—inside panelboards and load centers. With its compact molded-case design, it maximizes usable panel space while providing robust protection for three-phase electrical systems common in commercial and light industrial environments. The thermal-magnetic trip unit delivers stable, repeatable protection, helping you avoid nuisance trips without sacrificing quick response to short circuits.

Key advantages

• Space-efficient design: A compact molded-case footprint that fits neatly into standard panel spaces, helping you optimize layout and wiring routes in crowded enclosures.
• Thermal-magnetic protection: Combines a thermal element for overload detection with a magnetic element for rapid short-circuit tripping, providing predictable trip behavior across varying load conditions.
• High-current capability: 630A continuous rating makes it ideal for larger branch circuits and feeder protections in commercial and light-industrial panels.
• Three-pole, three-phase reliability: Specifically suited for 3-phase systems, ensuring balanced protection for all phases in a shared load center.
• OEM panel compatibility: Designed to be compatible with matching Eaton OEM load centers and panelboards for straightforward installation and reliable performance.
• Versatile applications: Suitable for residential, commercial, and light-industrial applications that require solid overcurrent and short-circuit protection.
