Square D BDA36110 Molded Case Circuit Breaker

Square D BDA36110 Molded Case Circuit Breaker is a 3-pole, 110-amp device from Schneider Electric’s PowerPact B-Frame lineup, designed for primary protection and switching in industrial power distribution panels. This molded-case breaker is rated for 600Y/347 VAC (commonly described as a 600 V class) and uses thermal-magnetic trip protection to respond to overloads and short circuits. The I-Line compatible BDA36110 is a fixed-trip, three-pole unit with an electrical interrupting rating of 14 kA at 600 VAC, providing robust protection for feeders and motor circuits in commercial/industrial applications. Depending on voltage, distributor listings show higher interrupting ratings (e.g., up to 25 kA at lower voltages such as 277/408 VAC or 240 VAC), reflecting the device’s flexibility across systems. Typical applications include protecting feeders to MCCs, motor control centers, and branch circuits in commercial buildings and manufacturing facilities where precise, reliable overcurrent protection is required. The 110 A rating makes it suitable for medium-scale distribution panels, and its PowerPact B-Frame architecture supports plug-in installation in compatible Square D panels, enabling straightforward replacement and maintenance of existing BDA-series MCCBs.
