Product FAQs
7 answersWhat panelboards are compatible with the JDA262255 breaker?
This breaker installs directly into Square D I-Line panelboards and switchboards. It uses a plug-in mounting style that connects directly to the panel busbar.
What does the 5 suffix in the JDA262255 catalog number mean?
The 5 at the end of the part number indicates a CA phase connection. Because I-Line panels use a stacked busbar design, 2-pole breakers must be ordered with the correct phase arrangement to align properly.
How does the I-Line mounting system work on the JDA262255?
The line side of the breaker features plug-on jaws that grip the panel busbar. This blow-on connection design uses magnetic forces during a short circuit to draw the jaws together, gripping the busbar more firmly.
What does the D indicate in the JDA262255 catalog number?
The D indicates the interrupting capacity level within the PowerPacT J-Frame series. This specific rating level provides up to 25kA at 240VAC, 18kA at 480VAC, and 14kA at 600VAC.
How is the trip unit configured on the JDA262255?
It features a thermal magnetic trip unit with fixed thermal and adjustable magnetic settings, providing standard long-time and instantaneous (LI) fault protection.
What wire sizes are accepted by the load lugs on the JDA262255?
The load-side terminals accept aluminum or copper conductors ranging from 3/0 AWG to 350 kcmil.
Is the JDA262255 part of the PowerPacT series?
Yes, it is a PowerPacT J-Frame molded case circuit breaker manufactured by Schneider Electric under the Square D brand.
