Product FAQs
10 answersIs the Square D JGL36250U33X rated for 80% or 100% continuous current?
This breaker is standard 80% rated. For a 100% continuous current rating in the same frame and trip unit, you would need the JGL36250CU33X.
What is the recommended tightening torque for the lugs on the JGL36250U33X?
The standard AL250JD line and load lugs for 3/0 AWG to 350 kcmil aluminum or copper wire should be torqued to 225 lb-in (25 N.m) using a 5/16 inch hex bit.
Can I install the JGL36250U33X in a Square D I-Line panelboard?
No, the JGL36250U33X is a unit mount (feed-thru) circuit breaker designed for individual mounting or use in NF panelboards, switchboards, and enclosures. For an I-Line panelboard, you will need the I-Line version, part number JGA36250U33X.
What is the difference between the JGL36250U31X and the JGL36250U33X?
The JGL36250U31X features a Micrologic 3.2 trip unit with standard LI (Long-time, Instantaneous) protection. The JGL36250U33X features the Micrologic 3.2 S trip unit, which adds Short-time protection (LSI: Long-time, Short-time, Instantaneous) for better system coordination.
Is the Micrologic trip unit on the JGL36250U33X field replaceable?
No. PowerPacT J-Frame breakers require a T or R suffix in the catalog number (e.g., JGL36250TU33X) to indicate a field interchangeable trip unit. The standard JGL36250U33X comes with a factory sealed trip unit that cannot be swapped in the field.
Can the JGL36250U33X be reverse fed?
Yes, the JGL36250U33X is suitable for reverse feeding. However, always verify that your specific application and local electrical codes permit reverse fed installations.
Does the JGL36250U33X include a push-to-trip button for testing?
Yes, like all PowerPacT J-Frame circuit breakers, it features an integral push-to-trip button on the cover. This allows you to manually trip the breaker to verify the mechanical operation of the tripping mechanism.
Are auxiliary switches or shunt trips field installable on the JGL36250U33X?
Yes, PowerPacT J-Frame breakers support a wide range of field installable internal accessories, including auxiliary switches, alarm switches, shunt trips, and undervoltage releases. These install behind the front cover of the breaker.
What does the LSI designation mean on the Micrologic 3.2 S trip unit?
LSI stands for Long-time, Short-time, and Instantaneous protection. Long-time protects against sustained overloads, Short-time provides a delayed trip for short circuits to allow downstream breakers to clear the fault first, and Instantaneous trips immediately under severe short circuit conditions.
Is the JGL36250U33X rated for use in DC applications?
No. While some thermal magnetic J-Frame breakers have DC ratings, breakers equipped with electronic Micrologic trip units, like the JGL36250U33X, are rated for AC voltage only.
