BDA36125 - 125Amp Circuit Breaker

BDA36125 - 125Amp Circuit Breaker

The Schneider Electric BDA36125 PowerPacT B-Frame circuit breaker is a 125A, 3-pole thermal-magnetic breaker designed for commercial and industrial power distribution systems. It provides protection against overloads and short circuits, helping you reduce the risk of damage to electrical equipment and wiring during fault conditions.

Its compact B-Frame construction makes it a practical choice for your panelboards, switchboards, motor control centers, and HVAC equipment where available space may be limited. The breaker features an I-Line plug-on connection on the line side and mechanical lugs on the load side, allowing for efficient installation and servicing. Schneider Electric's dual-break rotating contacts help reduce peak fault current during short-circuit events, while the integrated push-to-trip button allows technicians to quickly verify breaker operation during routine maintenance.

With a 14kA interrupting rating at 600Y/347VAC, an 80% continuous current rating, and compliance with widely recognized industry standards, the BDA36125 is well suited for a broad range of commercial and industrial applications. Whether installed in a new electrical distribution system or used as a replacement breaker, it delivers dependable circuit protection where reliability matters most.
