Schneider Electric BDA34100Y I-Line Circuit Breaker

Schneider Electric's Square D PowerPacT BDA B-Frame I-Line molded-case circuit breaker, model BDA34100Y, is a 100 A, 3-pole device designed for 480Y/277 VAC three-phase distribution. It uses I-Line plug-in mounting for quick installation in PowerPacT B-Frame panels and features a thermal-magnetic trip with long-time and instantaneous protection functions, plus load-side mechanical lug terminals for secure conductor connections. The BDA34100Y is rated for an 18 kA interruption at 480 VAC and is specified as 80% rated for continuous loads under ABC, aligning with heavy-load feeder applications in industrial panelboards that deploy Schneider Electric's I-Line gear. As a non-interchangeable-trip unit within the PowerPacT B-Frame family, it provides consistent protective characteristics across installations and is compatible with I-Line panelboards and switchboards for efficient, structured distribution of three-phase power. The package is intended for use in industrial control and distribution schemes that use Square D I-Line equipment, and it integrates with other PowerPacT components to form a cohesive protection scheme for feeders and motor circuits in commercial or light-industrial facilities.
