Square D BJA260401 PowerPacT B-Frame Molded Case Circuit Breaker – 2 Pole – 40A – 600Y/347VAC – I-Line Plug-In – Thermal Magnetic

The Square D BJA260401 is a PowerPacT B-Frame molded case circuit breaker designed for high-performance electrical protection in commercial and industrial power distribution systems. Manufactured by Schneider Electric under the Square D brand, this 2-pole, 40A breaker provides dependable thermal-magnetic (LI) protection for branch circuits requiring high interrupting capacity and compact I-Line installation.

Built with an I-Line style plug-in connection, the BJA260401 is engineered for fast, secure installation into compatible Square D panelboards and switchboards. It features AB phase configuration along with load-side mechanical lug terminals, supporting standardized panel layouts and efficient retrofit or new installation applications. The non-interchangeable trip unit ensures consistent protection characteristics and reliable operation over time.

With a high interrupting rating of 65kA at 480VAC, this breaker is suitable for demanding electrical environments where high fault currents may occur. Its compact design and robust construction make it ideal for OEM equipment, industrial control systems, and commercial distribution panels.
