Product FAQs
6 answersWhat older Square D circuit breaker does the BJA260901 replace?
The BJA260901 is the direct replacement for discontinued 90A, 2-pole F-Frame I-Line breakers, such as the FA26090AB and FH26090AB. The PowerPacT B-Frame fits into the exact same I-Line mounting space, allowing you to retrofit existing panelboards without modifying the bus.
What does the "1" at the end of the BJA260901 catalog number indicate?
The "1" suffix indicates an AB phase connection on the I-Line bus. This means the line-side jaws of the breaker will plug onto the A and B phases of your panelboard or switchboard.
What does the "J" in the BJA260901 part number mean?
The "J" designates the interrupting rating tier within the PowerPacT B-Frame series. For this breaker, it provides a 100kA rating at 240VAC, 65kA at 480VAC, and 25kA at 600Y/347VAC.
How does the BJA260901 connect to the panelboard and the load?
This I-Line breaker features a plug-on jaw connection on the line side that snaps directly onto the panelboard bus. The load side uses mechanical lugs that accept 14 AWG to 2/0 AWG aluminum or copper wire.
Does the BJA260901 feature current-limiting technology?
Yes, PowerPacT B-Frame breakers utilize dual-break rotating contacts. This design limits peak let-through current during a short circuit, which reduces the required busbar bracing and lowers enclosure pressure.
Is the BJA260901 rated for 100 percent continuous current?
No, like most standard thermal-magnetic circuit breakers, the BJA260901 is rated for 80 percent continuous current. It should be applied continuously at no more than 72 amps (80 percent of its 90A rating) per NEC guidelines.
