Feature → Business Impact → Application: Series G LG frame MCCB provides precise magnetic trip (T185) with fixed thermal, enabling predictable coordination in motor control centers and switchgear. This translates to faster fault isolation, reduced downtime, and lower maintenance costs in harsh industrial environments. The unit’s UL Listed, IEC rated, and CSA Certified status ensures compliance across global projects, minimizing risk during audits and enabling smoother procurement. The LGU3350FAG uses metric mounting hardware and line/load terminals, simplifying retrofit or new-panel installs in panel boards and control panels. With 350 A continuous rating and high interrupt ratings (200 kAIC at 240 Vac, 150 kAIC at 480 Vac, 65 kAIC at 600 Vac), it supports scalable protection for evolving plant loads while maintaining selectivity. A 4.09 in depth and 5.48 in width/height footprint improves panel packing density without compromising accessibility for maintenance.
