The LG-frame complete breaker integrates fixed thermal and adjustable magnetic trip, enabling selective coordination and faster fault clearance. This translates to reduced arc flash risk, minimized downtime, and lower energy losses in heavy machinery. Use in motor control centers and panel boards where precise trip settings are critical. With a 200 kAIC interrupt rating at 240 Vac and 100 kAIC at 415/480 Vac, the LGC4500FAG handles short-circuit events without unnecessary disconnection of healthy loads, supporting uptime in manufacturing lines. Voltage rating of 600 Vac and a four-pole design with line/load terminals plus metric mounting hardware simplifies installation and replacement, reducing field wiring complexity. Certifications and HACR rating ensure CE, UL Listed, and CSA Certified compliance, mitigating supplier risk in regulated projects and easing customer audits. Practical resources from Eaton, including application notes and catalogs, guide tap rules, terminations, and selective coordination, helping engineers design safer, more efficient panels. This MCCB is well-suited for control panels, switchgear, and OEM equipment where reliability and compliance drive project success.
