BDA36040 - 40Amp Circuit Breaker

BDA36040 - 40Amp Circuit Breaker

When reliable circuit protection matters, the Schneider Electric BDA36040 PowerPacT™ B-Frame Circuit Breaker is built to handle the job. Designed for commercial and industrial electrical systems, this 40A 3-pole thermal-magnetic breaker helps protect your distribution panels, HVAC equipment, motor loads, and feeder circuits from overloads and short circuits while keeping installations clean and efficient. Its compact B-Frame design fits neatly into I-Line panelboards and switchboards, making it a smart option for applications where panel space is limited.

The BDA36040 is designed with practical, everyday use in mind. Dual-break rotating contacts help reduce peak current during fault conditions, which can help limit stress on connected equipment and improve overall system protection.
