LG-frame compatibility delivers robust protection for main feeders in control panels, enabling scalable expansion and easier panel upgrades with minimal rework. Business impact includes improved protection coordination, reduced downtime, and lower total cost of ownership through standardized LG components in distributed electrical systems. Application: suitable for industrial switchgear and motor control centers requiring a four-pole, 630 A device with reliable thermal and magnetic trip action. The fixed thermal and fixed magnetic trip (T186) provides precise overload and short-circuit protection, decreasing equipment damage and accelerating fault clearance in high-load environments. Application-specific context: ideal for power distribution feeders in manufacturing lines and processing plants seeking predictable protection curves and repeatable performance. Interoperability with LG frame accessories simplifies installation in legacy panels and new builds alike.

FAQs
Yes, the LGX4630NN is designed for LG-frame installations and integrates smoothly with compatible panels. It is specified as a four-pole frame with terminals not included, so you can select field-installed lugs or compatible terminal kits from Eaton to match your panel design and conductor sizing.
The unit provides 65 kAIC interrupt rating at 600 Vac and 200 kAIC at 240–480 Vac. It uses fixed thermal and fixed magnetic trip (T186), delivering coordinated overload protection and fast short-circuit clearance for robust motor and feeder protection in industrial environments.
Yes. HACR-rated according to catalog notes, the LGX4630NN is suitable for control panels serving HVAC and motor loads. Its 630 A rating and four-pole design help ensure safe operation of 3-phase systems with neutral considerations, while maintaining precise protection without nuisance trips.
The LGX4630NN is UL Listed, CSA Certified, and CE Marked, reflecting rigorous safety testing and cross-border acceptance. This is critical for global projects requiring conformity to diverse regulatory regimes and reduces risk during international deployment.
With Eaton’s one-year warranty (or up to eighteen months from shipment) and reliable LG-frame components, maintenance planning becomes predictable. The high interrupt ratings, robust construction, and broad certifications contribute to lower unplanned downtime and extended panel service intervals, improving overall ROI for mission-critical electrical distributions.
