The 630A current rating delivers robust short-circuit protection for feeders and motor loads, with a fast trip characteristic that minimizes arc energy and equipment damage. This is paired with a compact molded-case form factor that eases panel layout and reduces overall enclosure size, improving wiring efficiency and cooling performance. ARMS with collars provides secure, quick mechanical attachment, shortening installation time and increasing reliability in vibration-prone environments. The 1 in product depth, height, and width support dense installations while keeping handling simple, thanks to an approachable 1 lb weight. Compatibility with LSIG frames and standard MCCB accessories means easier retrofits and plug-in adaptations across existing control panels. For engineers, Eaton’s Series G design shortens design cycles and reduces field coordination risk, thanks to consistent terminology and a broad ecosystem of application notes and lug options.

FAQs

LGH363039GC is designed for standard Series G MCCB installations and compatible with LSIG frame accessories. When selecting for a specific panel type, verify mounting hardware, bus bar spacing, and enclosure clearance. This model’s compact 1 in footprint aids dense panel layouts, while ARMS with collars simplifies secure attachment during retrofits or new builds.
Key specs include a 630A current rating and molded case construction for robust short-circuit protection. Focus on trip curve type, interrupting capacity, and coordination with downstream protections. For motor loads, confirm coordination with overload relays and AC drives to prevent nuisance trips and ensure safe motor starting sequences.
Certification suitability depends on configuration. Compliances for this model should be confirmed with Eaton, but Series G MCCBs are commonly implemented in CE/UL environments when properly specified. Always ensure enclosure rating, wiring methods, and accessory compatibility meet your local regulatory requirements and panel design standards.
For hazardous environments, verify applicable standards such as CE, UL, and any region-specific certifications with Eaton. In practice, MCCBs used in harsh industrial settings should be installed with suitable enclosure protection, proper IP ratings, and vibration-resistant mounting. Always confirm the exact certification scope with the manufacturer for your installation location.
Benefits include reduced downtime due to reliable overcurrent protection and easier maintenance from the secure ARMS mounting and compact form factor. The standardized Series G platform facilitates faster sourcing, smoother spares management, and scalable protection across multiple feeders, delivering lower total cost of ownership over the life of the panel.
