FAQs

Installation requires a three‑pole arrangement with an LG frame MCCB. The unit ships without terminals, so select compatible lug or terminal accessories and follow tap rules documentation to ensure safe terminations. Verify panel clearance, mounting orientation, and alignment with adjacent devices to maintain proper protection coordination and ease future maintenance.
LGU3630AAW provides a 630 A amperage rating at 600 Vac, three‑pole configuration, and adjustable thermal/magnetic trip. Interrupt ratings include up to 200 kAIC at 240 Vac and 150 kAIC at 415–480 Vac, with 65 kAIC at 600 Vac. These specs support robust protection for motors, feeders, and critical loads in industrial settings.
Yes. The LGU3630AAW uses an LG frame and Series G architecture with adjustable trip for flexible motor protection in panel boards and motor control centers. While designed for IEC markets with adjustable trip units, it is UL Listed and HACR rated, making it a solid choice for both HVAC-driven and general industrial panels when coordinated with other protection devices.
The LGU3630AAW is UL Listed and HACR rated, indicating suitability for HVAC and general industrial protection applications. While the catalog notes address IEC-style trip units, users should confirm local code requirements and ensure appropriate listings for their specific installation environment, using Eaton's data sheets and installation notes as references.
Eaton provides comprehensive resources including Application Notes on tap rules for molded case breaker terminals, MOEM MCCB product selection guides, installation datasheets, and Series G technical brochures. These documents assist with correct wiring, coordination, and maintenance planning, and there are also warranty terms and service-center references to support lifecycle management.
