The BJA261001 is a 2-pole, 100A molded case circuit breaker from the Square D PowerPacT B-Frame family. Built for commercial and industrial power distribution, it provides reliable overcurrent protection. This unit features an AB phase connection and installs into Square D I-Line panelboards and switchboards. It serves as a drop-in replacement for legacy FH26100AB breakers. Rated 65 kAIC at 480VAC, it utilizes fixed thermal-magnetic trip technology (LI) and is HACR certified.
What legacy Square D circuit breakers does the PowerPacT BJA261001 replace?
The PowerPacT B-frame series is the direct replacement for legacy Square D F-frame breakers. The BJA261001 serves as a drop-in replacement for older 100A, 2-pole FA or FH series breakers, such as the FH26100AB, in I-Line panelboards.
What type of panels is the BJA261001 compatible with?
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 will not fit standard unit-mount or load center applications.
Does the BJA261001 come with lugs installed?
Yes, this I-Line breaker includes factory-installed mechanical lugs on the load side that accept 14 AWG to 2/0 AWG aluminum or copper wire. The line side utilizes a plug-in jaw connection.
What does the J in the BJA261001 part number signify?
In the PowerPacT B-frame nomenclature, the J designates the interrupting rating tier. For this breaker, it indicates a high interrupting capacity of 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600Y/347VAC.
Are the trip settings on the BJA261001 adjustable?
No, this breaker utilizes a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip functions are factory-set and cannot be adjusted in the field.
How does the I-Line connection work on the BJA261001?
The breaker uses a plug-in jaw connection on the line side that snaps directly onto the busbar of an I-Line panelboard. The load side utilizes standard mechanical lugs for wire termination.
Which busbar phases does the BJA261001 connect to?
This specific 2-pole breaker is configured with an AB phase connection, meaning its line-side jaws will connect to the A and B phases of the I-Line panelboard busbar.
