MOEM MCCB product selection guide
4P configuration provides complete protection for three-phase loads and neutral conductors, delivering coordinated tripping and consistent protection across phases. Business impact: simplifies wiring diagrams, reduces panel wiring errors, and improves selective coordination with downstream protection devices. Application: suitable for three-phase motor drives, conveyors, stamping presses, and control panels where reliable trip performance is critical and down-time costs are high. 1200A rating with 100% rated operation ensures the device maintains performance under full load, avoiding nuisance trips in peak conditions. Impact: lowers unplanned downtime, reduces maintenance interventions, and supports future capacity increases without device swaps. Application: heavy-duty power feeds, large automation stations, and main distribution segments in manufacturing environments. Compact 1 in by 1 in by 1 in footprint and 1 lb weight enable denser panel layouts and easier retrofit work. Impact: saves enclosure space, lowers cabinet fabrication costs, and simplifies logistics for field installation. Application: retrofit projects, modular control panels, and compact machine enclosures where space is at a premium. ENGLISH TAPPED TERMS and molded case construction streamline field wiring and terminations, delivering consistent connection quality. Impact: reduces installation time, minimizes miswiring risk, and improves long-term contact reliability. Application: panel builders and integrators seeking dependable terminations in low-profile MCCB applications. Series G compatibility with adapters, lugs, and extensive Eaton documentation supports scalable protection strategies and future upgrades. Impact: enables selective coordination, faster commissioning, and easier maintenance planning across multi-bay panels. Application: plant-wide protection schemes, modular cabinets, and expansions in industrial facilities.
