Schneider Electric BDA34015YNN Molded-Case Circuit Breaker

Schneider Electric's BDA34015YNN Molded-Case Circuit Breaker is a 3-pole, 15 A PowerPact B-frame molded-case circuit breaker designed for 480Y/277 VAC three-phase systems. It provides thermal-magnetic protection with an 18 kA short-circuit interrupting rating at 480 VAC, making it suitable for feeders and branch circuits in commercial and light industrial panels. The unit uses I-Line mounting to align with Schneider Electric panel buses for straightforward installation in compatible panels and panelboards. This UL 489-listed MCCB supports 50/60 Hz operation and is part of the PowerPact B family, with a catalog designation that matches the BDA34015Y models. The device is designed to trip on overloads or short circuits in 3-phase circuits, helping protect downstream equipment such as motors, pumps, and control panels from damage due to overcurrent.
