Product FAQs
8 answersWhich panelboards are compatible with the JLL36175 breaker?
This unit mount breaker is designed for use in Square D NQ and NF panelboards, QED switchboards, industrial control panels, and motor control centers. It requires appropriate unit mount hardware or enclosures, as it is not an I-Line plug-on breaker.
Is the JLL36175 an I-Line or unit mount breaker?
This specific catalog number is a unit mount breaker, meaning it bolts directly to the mounting surface and connects via cables. If you need the I-Line plug-on version for an I-Line panelboard, you will need the JLA36175 catalog number.
What does the 'L' in the JLL36175 part number signify?
The second 'L' indicates the interrupting rating level within the PowerPacT J-Frame family. The L-interrupting tier provides 100kA at 480VAC. This is higher than the D, G, and J tiers, making it suitable for systems with very high available fault currents.
Can the trip settings on the JLL36175 be adjusted?
This breaker features a thermal-magnetic trip unit with fixed thermal protection for overloads and adjustable magnetic protection for short circuits. The instantaneous magnetic trip threshold can be tuned to coordinate with other devices in your electrical system.
What does the 'LI' trip function code mean on this breaker?
The LI designation means the trip unit provides Long-Time (L) and Instantaneous (I) protection. Long-Time protects against sustained overloads, while the Instantaneous function protects against sudden short circuits.
Are the line and load lugs included with the JLL36175?
Yes, as a unit mount breaker, it comes standard with mechanical lugs on both the line and load sides for feed-thru connection. These lugs accept 4 AWG to 4/0 AWG aluminum or copper conductors.
What type of wire and gauge range does the JLL36175 accept?
The standard mechanical lugs on this breaker accept aluminum or copper wire ranging from 4 AWG to 4/0 AWG. Ensure proper torque specifications are followed during installation as noted on the breaker faceplate.
What safety precautions should be taken before installing the JLL36175?
Always de-energize the panelboard or switchboard before installation. Verify that the system voltage and available fault current do not exceed the breaker's maximum ratings of 600VAC and 125kAIC at 240VAC. Installation should only be performed by a qualified electrician following local electrical codes.
