Product FAQs
6 answersWhat types of panels and enclosures are compatible with the JLL36150 circuit breaker?
This unit-mount J-Frame breaker is designed for use in Square D NQ and NF panelboards, QED switchboards, industrial control panels, and motor control centers.
What wire sizes and torque specifications apply to the standard lugs on the JLL36150?
The standard AL175JD lugs accept 4 AWG to 4/0 AWG aluminum or copper wire. The required tightening torque for these terminals is 221 lb-in (25 N.m).
Can the Square D JLL36150 be reverse fed?
Yes. Standard unit-mount PowerPacT J-Frame circuit breakers with factory-sealed thermal-magnetic trip units can be reverse fed.
Does the JLL36150 include a mechanism for manual testing?
Yes. This PowerPacT J-Frame breaker features an integral push-to-trip button on the cover, allowing you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
Is the JLL36150 rated for 80% or 100% continuous current?
This standard JLL36150 breaker is rated for 80% continuous current. For a 100% rated version, you would need the JLL36150C catalog number.
What do the letters "LL" indicate in the JLL36150 catalog number?
The first "L" designates the interrupting rating (125kA at 240V, 100kA at 480V, and 50kA at 600V). The second "L" indicates the mounting style, meaning it is a unit-mount breaker with lugs on both the line and load sides.
