Product FAQs
10 answersWhat is the recommended tightening torque for the lugs on the JDL36250?
The standard AL250JD lugs accept 3/0 AWG to 350 kcmil aluminum or copper wire and should be torqued to 225 lb-in (25 N.m).
Does the JDL36250 come with lugs installed on both sides?
Yes, as a feed-thru unit mount circuit breaker, the JDL36250 includes standard AL250JD mechanical lugs factory-installed on both the line and load sides.
Can the JDL36250 circuit breaker be reverse fed?
Yes, standard thermal-magnetic PowerPacT J-frame circuit breakers like the JDL36250 are suitable for reverse-fed applications.
What does the 'D' in the JDL36250 part number represent compared to a JGL or JJL?
The middle letter indicates the breaking capacity code. The 'D' in JDL designates a standard interrupting rating. A JGL offers a high rating (35kA at 480VAC), and a JJL provides an extra-high rating (65kA at 480VAC).
Can I install the JDL36250 in a Square D I-Line panelboard?
No, the JDL36250 is a unit mount circuit breaker designed with feed-thru lug connections. For an I-Line plug-on connection with standard interrupting ratings, you will need catalog number JDA36250.
Does the JDL36250 feature an adjustable trip unit?
The JDL36250 is equipped with a thermal-magnetic trip unit that has a fixed thermal (overload) setting of 250A and an adjustable magnetic (instantaneous short-circuit) setting. The instantaneous pickup can be adjusted using a dial on the front of the breaker.
Is the JDL36250 rated for 100% continuous current?
No, the standard JDL36250 is rated for 80% continuous current. If you require a 100% rated version, you must specify the catalog number with a 'C' suffix (JDL36250C).
Which standalone enclosures are compatible with the JDL36250?
For standalone mounting, the JDL36250 is compatible with Square D J-Frame 250A enclosures. Common options include the J250S (NEMA 1 Surface Mount), J250F (NEMA 1 Flush Mount), J250R (NEMA 3R), and J250DS (NEMA 4/4X/5 Stainless Steel).
Are field-installable accessories available for the JDL36250?
Yes, the PowerPacT J-frame supports a variety of field-installable accessories. Common additions include shunt trips (such as the S29386 for 110-130VAC), undervoltage releases, and auxiliary switches, which install internally under the breaker cover.
Is the JDL36250 circuit breaker HACR rated?
Yes, the JDL36250 is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment.
