Product FAQs
6 answersWhat is the adjustable magnetic trip range for the JDL26250?
The magnetic trip function on this 250A breaker is adjustable from a low setting of 1250A to a high setting of 2500A.
What is the recommended lug torque for the JDL26250?
The factory-installed lugs require a tightening torque of 230 lbf-in (26 N.m) when terminating 3/0 AWG to 350 kcmil aluminum or copper conductors.
Can the Square D JDL26250 be reverse fed?
Yes. Because it features a thermal-magnetic trip unit and is not restricted by LINE and LOAD markings, this PowerPacT J-frame breaker can be reverse fed for supply-side applications.
What does the letter D in the JDL26250 catalog number signify?
The letter D designates the breaker's interrupting capacity tier within the PowerPacT J-Frame series. This specific tier provides 25kA at 240VAC, 18kA at 480VAC, and 14kA at 600VAC.
Is the JDL26250 compatible with Square D I-Line panelboards?
No. The JDL26250 is a unit-mount breaker designed for industrial enclosures, switchboards, and control panels. I-Line panelboards require a plug-on J-frame breaker, typically designated with the letter A in the third position of the catalog number.
Does the JDL26250 include line and load lugs?
Yes, this unit-mount breaker comes standard with factory-installed mechanical lugs (catalog number AL250JD) on both the line and load sides.
