Square D BDA36090 Circuit Breaker

Square D PowerPact B-Frame BDA36090 is a 3-pole molded-case circuit breaker rated for 90 amperes, designed for 600Y/347 VAC systems and compatible with PowerPact B-Frame I-Line assemblies in industrial distribution panels. It offers thermal-magnetic protection and an interrupting rating that varies with voltage: 14 kAIC at 600 VAC, 18 kAIC at 480 VAC, and up to 25 kAIC at 240 VAC, making it suitable for safeguarding feeders, motors, and downstream equipment from short circuits. As part of the PowerPact B-Frame lineup, this MCCB is intended for use in motor control centers and large distribution panels where a 90 A, 3‑pole device is required. The BDA36090 is a standard 90 A Square D device from Schneider Electric’s Square D brand, designed for medium‑voltage, I‑Line installations and commonly specified for industrial and commercial facilities that need reliable, code‑compliant protection for 3‑phase circuits.
