Product FAQs
6 answersWhich panelboards are compatible with the JDA262502 breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes a specialized I-Line plug-on connection and will not fit standard QO load centers or NQ and NF series panels.
What does the "D" signify in the JDA262502 catalog number?
In the Square D PowerPacT J-Frame series, the "D" indicates the interrupting rating tier. It signifies a standard D-interrupting level, which provides 18kA at 480VAC and 25kA at 240VAC, helping you match the breaker to your system's available fault current.
Can I adjust the trip settings on the JDA262502?
This breaker features a thermal-magnetic trip unit with a fixed thermal element for standard overload protection and an adjustable magnetic element. The adjustable magnetic trip allows installers to fine-tune the instantaneous short-circuit response based on the specific load.
Can this 2-pole breaker be installed in a 3-phase I-Line panel?
Yes, 2-pole I-Line breakers can be installed in 3-phase panelboards to feed single-phase loads. The breaker will connect to two of the three available busbars depending on where it is positioned on the I-Line bus stack.
Is the JDA262502 a direct replacement for older Square D breakers?
Yes, as part of the PowerPacT J-Frame family, it can replace legacy Square D J-frame breakers that utilize the same I-Line plug-in mounting. Always verify that your panel has sufficient mounting space and meets current interrupting requirements before retrofitting.
Are there specific wiring requirements for using this breaker in a DC system?
While the JDA262502 is rated for up to 250VDC, DC installations require specific pole wiring configurations to safely interrupt direct current arcs. Always consult the Schneider Electric instruction bulletin for the correct series wiring of poles in DC applications.
