Product FAQs
6 answersDoes the PowerPacT BJA260301 replace older Square D circuit breakers?
Yes, the PowerPacT B-frame is the modern replacement for legacy Square D F-frame breakers, including the FA and FH series. It maintains the same 1.5-inch per pole width and I-Line mounting dimensions, making it a direct drop-in replacement for existing I-Line panelboards and switchboards.
What does the J in the BJA260301 part number signify?
The J indicates the interrupting rating tier within the PowerPacT B-frame family. A J-interrupting breaker provides a high interrupting capacity of 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600Y/347VAC.
What type of panelboards are compatible with the BJA260301?
This breaker features an I-Line style plug-in connection on the line side, making it exclusively compatible with Square D I-Line panelboards and switchboards. It cannot be used in standard load centers or NQ/NF panelboards.
How does the line-side connection work on the BJA260301?
The breaker utilizes Square D's I-Line plug-on design. The line side features shrouded jaws that press directly onto the I-Line bus stack, secured by an integrated mounting bracket. This eliminates the need for line-side cabling or bolt-on hardware.
What are the recommended lug torque specifications for the load side of this breaker?
For the mechanical load-side lugs, the recommended tightening torque is 44.3 lb-in (5 N.m) for 14 to 4 AWG wire, and 79.7 lb-in (9 N.m) for 3 to 2/0 AWG wire. Always verify with the manufacturer instructions provided with the breaker.
Can the BJA260301 be used in DC voltage applications?
Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, with a DC interrupting rating of 50kA.
