High interrupt ratings provide robust fault energy management, reducing equipment damage and boosting uptime for critical processes in manufacturing and data centers. LGX3350FAG delivers 200 kAIC at 240/480 Vac and 65 kAIC at 600 Vac, supporting fast fault clearance and safe operation under heavy loads. This translates to lower risk of costly downtime and enables safer commissioning and maintenance practices. The product’s three-pole LG frame with fixed thermal and adjustable magnetic trip (T185) enables precise coordination and reliable protection for motors and feeders, minimizing nuisance trips while ensuring protection for the most demanding loads. The 350 A rating aligns with medium-to-high current circuits, helping engineers stay within panel ratings and avoid oversized protection while maintaining safety margins. Line and load terminals with metric mounting hardware streamline installation, reducing wiring time and errors during panel assembly. UL Listed, IEC Rated, CSA Certified, and CE Marked compliance, plus HACR rating, simplify cross-border deployments and supplier qualification. The Series G design supports compatibility with modern switchgear and motor control centers, while 50/60 Hz operation ensures suitability for global facilities. With a compact footprint (4.09 in length, 5.48 in height and width) and a weight of 11.9 lb, it fits space-constrained panels and reduces handling effort during installation. Eaton’s warranty policy (25-000) provides coverage for one year from installation or eighteen months from shipment, offering reassurance for project schedules and service planning.
