Feature → Business Impact → Application: The LGS3630AAG uses an LG-frame, three-pole design rated at 630 A and 600 Vac, enabling robust protection for large machines and control panels while keeping a compact footprint in spaces with limited enclosure depth. This translates to improved fault isolation and reduced risk of equipment damage in industrial automation applications. Application: Suitable for panel builders and OEMs needing reliable 3P protection in HVAC, manufacturing lines, and utility panels. Feature → Business Impact → Application: Adjustable thermal and magnetic trip units provide tailored coordination for diverse loads and short-circuit scenarios, decreasing nuisance trips and enabling precise selectivity in complex machines. Application: Ideal for IEC markets and environments requiring configurable protection without over-protection penalties. Feature → Business Impact → Application: Line and load terminals with metric mounting hardware streamline installation and reduce field wiring errors, cutting assembly time and improving repeatability across large rollout projects. Application: Used in new installations and retrofit projects where quick, dependable protection is essential. Feature → Business Impact → Application: 85 kAIC at 240 Vac, 50 kAIC at 415/480 Vac, and 25 kAIC at 600 Vac interrupt ratings offer scalable fault current handling, reducing downstream damage and easing utility/interconnection compliance. Application: Critical for data centers, motors, and process lines with variable fault levels. Feature → Business Impact → Application: UL Listed and HACR-rated design communicates compliance and suitability for commercial and industrial systems, enabling easier customer acceptance and safer operation. Application: Global deployment in control panels and machine enclosures where certification and performance assurance matter most. Feature → Business Impact → Application: Mounting in Metric hardware and LG frame compatibility ensures straightforward integration with Eaton System G products and compatible bus/rail schemes. Application: New builds and retrofits requiring standardized protection modules with predictable lifecycle costs.
