Product FAQs

5 answers
What panelboards are compatible with the BDA36040 circuit breaker?

The BDA36040 is an I-Line style plug-in breaker designed exclusively for use in Square D I-Line electrical panelboards and switchboards. It is not compatible with NQ or NF series panels, which require different mounting styles.

Can the PowerPacT BDA36040 replace older Square D FA or FH frame breakers?

Yes, the Schneider Electric PowerPacT B-frame series serves as the direct replacement for legacy F-frame (FA and FH) molded case circuit breakers. It fits into the same I-Line panelboard mounting space footprint, allowing for straightforward retrofits.

What phase connection does the BDA36040 have?

This 3-pole breaker comes configured with a standard ABC phase connection for I-Line busbars. In the PowerPacT catalog logic, a standard ABC connection is indicated by the absence of a specialized phase option suffix at the end of the part number.

What does the D in the BDA36040 catalog number represent?

The letter D designates the interrupting rating class within the PowerPacT B-frame family. This specific class provides short-circuit protection ratings of 25 kA at 240V, 18 kA at 480V, and 14 kA at 600Y/347V AC.

What are the load-side wire capacity limits for this breaker?

The factory-installed mechanical lugs on the load side of the breaker accept solid or stranded aluminum or copper (Al/Cu) conductors ranging from 14 AWG to 2/0 AWG. The line side requires no wiring, as it utilizes the integral I-Line plug-on jaws.

    Installed & working

    Ordered this from SuperBreakers when local vendors were quoting me 25%+.

    So I got a refurbished version of this breaker.

    It is installed and working.

    Also, service was great.

    Thank you SuperBreakers!
