Eaton LGS4500FAG MCCB - UL Listed

Feature → Business Impact → Application The LG-frame complete breaker design provides rugged, space-efficient protection in demanding environments, reducing panel footprint while maintaining reliability across circuits up to 500 A. This translates to lower install costs and easier retrofits in existing panels, especially in control rooms and machine enclosures that demand compact, high-current protection. The fixed thermal, adjustable magnetic trip (T185) delivers precise overcurrent protection with flexible coordination, enabling engineers to fine-tune protection without unnecessary nuisance trips, improving line uptime and asset longevity in process lines and manufacturing cells. Four-pole configuration with line and load terminals supports balanced protection of multi-wire circuits, simplifying wiring schemes and enhancing safety during maintenance and fault isolation. The LG frame, HACR rating, and 0% protected neutral pole specification provide predictable performance for motors and devices in commercial and industrial applications, aiding compliance with industry standards and reducing risk during commissioning. The device supports metric mounting hardware for standardized installation across global facilities, accelerating procurement and reducing installation time. With interrupt ratings of 25 kAIC at 600 Vac, 85 kAIC at 240 Vac, and 50 kAIC at 415/480 Vac, it delivers rapid fault interruption and scalable protection for varied load profiles, improving short-circuit resilience in panelboards and switchgear assemblies. The product’s compatibility with UL, CSA, and CE requirements helps streamline sourcing for multinational projects, while its 7.22 in dimensions and 20 lb weight aid mechanical engineers in enclosure planning and rack layout. Finally, the included catalog notes highlighting HACR capability reassure design teams that the MCCB is suitable for motor control environments, reducing design iterations and facilitating faster project delivery.
