Eaton LGU3630NN Molded Case Circuit Breaker - 630A, 600VAC

LGU3630NN uses an LG-frame molded case construction with fixed thermal and fixed magnetic trip, delivering precise overcurrent protection for feeders, motors, and control circuits. This architecture supports fast fault clearance while minimizing nuisance trips that disrupt production. The three-pole design and frame-only option simplify mounting in compact control panels. At 630 A, this breaker handles high-load feeders common in machine rooms and process lines, enabling safer power distribution without oversized components. The 600 VAC rating covers typical North American industrial networks, while the 240/415/480 VAC interruption ratings accommodate diverse installations. Field-accessory options from Series G improve selective coordination. Interruption ratings of 65 kAIC at 600 VAC and up to 200 kAIC at 240 VAC provide robust fault tolerance for short circuits, protecting equipment and wiring from damage. This makes the LGU3630NN suitable for motors with high inrush and intensive start-up sequences. Frame-only design and terminals without terminals offer flexible wiring and easy integration with customer-specified lugs or bus bars. The LG frame supports HACR compatibility and is CE marked, meeting global electrical standards. With UL Listed and IEC rated certifications, you gain confidence in meeting safety requirements across facilities. Compatibility and installation advantages include quick accessory selection through Eaton's product ecosystem, a consistent mounting footprint, and straightforward replacement in legacy Series G installations. Beyond protection, LGU3630NN contributes to total cost of ownership reductions by enabling selective coordination, reducing downtime, and simplifying spare-part inventories for large panel builds and OEM projects.
