Schneider Electric LA34225MC1677 Circuit Breaker

Schneider Electric's PowerPact LA34225MC1677 is a 225-amp molded‑case circuit breaker rated for 480 V AC, designed for protection of distribution circuits in commercial and industrial panels. As part of the LA/LH/Q4 family, this MCCB delivers thermal‑magnetic, overload and short‑circuit protection in a compact enclosure suitable for demanding environments. The LA34225MC1677 supports field installation of accessories in the PowerPact LA/LH/Q4 line, including the LA11021 shunt-trip accessory (120–240 VAC) for remote tripping and enhanced safety controls. This combination enables remote or centralized shutdown schemes while preserving fast, reliable interruption when faults occur. Applications include feeders and main distribution within electrical distribution systems that employ molded-case breakers, where dependable protection and coordinated control are essential. The LA series' legacy design emphasizes straightforward operation and broad compatibility with PowerPact components, ensuring that the LA34225MC1677 can integrate with existing Schneider Electric protection schemes while meeting 480 V system requirements. With its 225 A rating and 480 V capability, it is suitable for feeding branch circuits and main distribution in medium-sized panelboards where reliable trip performance is critical.
