Product FAQs
9 answersWhat type of panelboards is the BJA260204 compatible with?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features a plug-on design that connects directly to the I-Line bus.
What does the "4" suffix indicate on this breaker?
The "4" at the end of the BJA260204 catalog number indicates a BC phase connection. This determines which two phases of the I-Line bus the breaker will draw power from.
Does the PowerPacT B-frame replace older Square D breakers?
Yes, the PowerPacT B-frame is the direct, designated replacement for legacy Square D F-frame circuit breakers, including the older FA and FH series I-Line models. It fits into the same mounting space to simplify retrofits.
What wire material is compatible with the load-side lugs?
The mechanical lugs on this breaker accept both Aluminum (Al) and Copper (Cu) conductors, accommodating wire sizes from 14 AWG up to 2/0 AWG.
How does the I-Line mounting system work on this breaker?
The line side features shrouded plug-on jaws that press directly onto the panelboard bus, while the load side uses standard mechanical lugs for wire termination. A retaining bracket secures the breaker to the panel.
How can I manually test the tripping mechanism?
This breaker includes an integral push-to-trip button on the front cover, allowing you to manually trip the device to verify the mechanical operation is functioning correctly.
What internal contact design does the PowerPacT B-frame use?
It is equipped with dual-break rotating contacts. This design helps reduce the amount of peak current during a short-circuit fault, providing enhanced thermal-mechanical circuit protection.
Can this breaker be used in DC power applications?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, with an interrupting capacity of 50kA.
What does the "J" in the BJA prefix represent?
In the PowerPacT nomenclature, the "J" designates the interrupting rating tier. For this model, it provides a 65kA interrupting capacity at 480VAC and 100kA at 240VAC.
