Product FAQs
8 answersWhat panels accept the BJA260804?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It will not fit in standard load centers or NQ/NF panels.
What phase connection does the BJA260804 use?
The 4 suffix in the catalog number indicates it is configured for a BC phase connection on the I-Line bus. It will draw power specifically from the B and C phases of a 3-phase system.
What older breaker models can the BJA260804 replace?
This PowerPacT B-Frame breaker is a direct replacement for legacy Square D FH26080BC circuit breakers, offering upgraded technology in a compatible form factor.
How does the I-Line mounting system work for this breaker?
The I-Line plug-in design allows the breaker to snap directly onto the panelboard bus stack. This eliminates the need for separate mounting hardware or wire connections to the bus, significantly speeding up installation.
What does the LI trip function indicate on the BJA260804?
The LI designation means the thermal-magnetic trip unit provides Long-Time (overload) and Instantaneous (short-circuit) protection. Both the thermal and magnetic settings are fixed on this model and cannot be adjusted in the field.
Can the BJA260804 be used in DC applications?
Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, providing a 50kA interrupting capacity for applications like battery backups or industrial DC control panels.
Does this breaker feature current-limiting technology?
Yes, PowerPacT B-Frame breakers like the BJA260804 utilize dual-break rotating contacts. This design reduces peak current and let-through energy during a short-circuit fault, enhancing overall equipment protection.
What frame size is the BJA260804?
It is part of the Square D PowerPacT B-Frame family, which features a compact design with a maximum frame rating of 125 amps.
