630 A and 600 Vac ratings enable protection of high-current, three-phase feeders with minimal voltage drop and reliable fault interruption, reducing downstream equipment damage and downtime. The three-pole LG frame supports balanced protection across all phases, simplifying wiring and improving coordination in motor and process circuits. Adjustable thermal and magnetic trips provide tailored protection curves, lowering nuisance tripping while meeting system-wide safety requirements. High interrupt ratings—up to 100 kAIC at 240 Vac and 70 kAIC at 415 Vac—offer robust fault handling for demanding industrial environments, improving system reliability. Line and load terminals with metric mounting hardware support fast, compliant installations across global panels, while UL Listed and HACR-rated capabilities streamline building and equipment compliance for HVAC and control applications. Comprehensive documentation and compatibility with IEC markets help shorten commissioning cycles and reduce engineering risk.
