Schneider Electric BDA34100Y PowerPact I-Line Breaker

Schneider Electric's PowerPact B-frame molded-case circuit breaker, model BDA34100Y, delivers 100 A, three-pole protection for 480Y/277 VAC three-phase systems using I-Line plug-on mounting for compact, field-installable integration into PowerPact panels. It carries 18 kA short-circuit interrupting capacity at 480 V and is a thermal-magnetic MCCB configured for ABC phase connection, designed for an 80% continuous-load rating and reliable performance in distribution panels and feeder circuits across commercial and light-industrial environments. The BDA34100Y provides standard trip coordination with upstream devices, including long-time and instantaneous trip functions, while load-side terminations accommodate straightforward wiring within PowerPact panelware. UL-listed for 480Y/277V service, this 3P breaker is part of Schneider Electric's PowerPact B-Frame family, which spans 100–1000 A and supports consistent protection characteristics across the lineup. Its I-Line mounting and compact footprint are intended to simplify panel design and expansion, making it well suited for 480Y/277V distribution where space and reliable overcurrent protection are priorities.
