Square D JJL36175 – Frequently Asked Questions

1) What wire size do the lugs on the Square D JJL J-Frame breaker accept?
Line and load lugs on the JJL PowerPacT J-Frame take AWG 3/0 through 350 kcmil aluminum or copper conductors, torqued to 25 N.m. If your feeder is sized smaller than 3/0 or larger than 350 kcmil, these lugs won't terminate it and you need a different frame or a lug kit sized to the conductor.
2) Will the JJL PowerPacT breaker fit my 480V or 600V three-phase panel?
The JJL is rated 600VAC, 3-pole, so it covers 480Y/277 and 600V three-phase systems as well as anything below. Interrupting capacity is 25kA at 600VAC, so your available fault current at the point of installation has to be at or under 25kA for this breaker to be a legal choice.
3) Is the JJL breaker approved for HVAC and refrigeration equipment circuits?
Yes, the JJL is an HACR rated circuit breaker application, which is what air conditioning and refrigeration equipment nameplates typically call for on the branch circuit. It is UL Listed, CSA Certified and NOM Certified, and built to IEC 60947-2 and 60947-3.
4) Can an Eaton BAB Quicklag breaker be used instead of a Square D JJL J-Frame?
No, they are not interchangeable. The Eaton BAB-302 Quicklag is a three-pole thermal-magnetic breaker rated 240V, while the Square D JJL PowerPacT J-Frame carries a 600V rating with 25kA interrupting capacity. The BAB family is a bolt-on branch breaker; the JJL is a molded case device landing on lugs sized for AWG 3/0...350 kcmil conductors. For a 600V feeder or a 175A-200A motor circuit, the BAB is not a substitute.
5) If I need more than 200A on a 3-pole 600V circuit, what should I look at instead of the JJL?
The Square D JJL PowerPacT J-Frame family tops out at a 200A Motor FLA rating. For a larger 3-pole frame, the Eaton 6602C72G67 is a Series C K-Frame 400A 3-pole breaker with an interchangeable rating plug, which lets the trip rating be set within the frame rather than fixed by model. Confirm the K-Frame's mounting footprint and lug range against your enclosure, since the J-Frame measures 7.52 in high by 4.09 in wide by 3.39 in deep.
6) How much room do I need in the enclosure for a J-Frame JJL breaker?
Plan for a body measuring 7.52 x 4.09 x 3.39 inches (height x width x depth) plus wire-bending space for the 3/0 to 350 kcmil lug terminations. Front cover protection is IP40.
7) Is a thermal magnetic trip unit the right choice, or do I need electronic trip?
Thermal magnetic is the straightforward pick for a fixed feeder or a motor circuit sized to a known full-load amperage: the bimetal handles overload, the magnetic element handles short circuit, and there is nothing to program. The JJL's trip rating is fixed at 175A or 200A and the unit is not field serviceable, so if you need adjustable long-time or short-time pickup, ground-fault pickup, or metering, specify an electronic-trip J-Frame instead.
8) What else does ZenSupply carry if the J-Frame is the wrong size for my 3-pole molded case application?
For a molded case 3-pole at a different frame size, the ABB A2A150TT in the A2 Series and the ABB XT4 and XT5 3-pole breaker kits are alternatives. For a larger mining-duty application there is the Eaton Series C K-Frame 400A 3-pole with an interchangeable rating plug. Be aware the Eaton BAB Quicklag 3-pole is a 240V bolt-on branch breaker, not a 600V molded case device, so it is not a substitute for a JJL.
9) Should I pick the JJL36175 or the JJL36200?
Both Square D PowerPacT J-Frame breakers share the same 600VAC rating, 25kA interrupting capacity, 3-pole configuration, 80% continuous current application, and lugs for AWG 3/0...350 kcmil aluminum/copper conductors at 25 N.m. The difference is the motor full-load-amperage rating: JJL36175 is the 175A unit and JJL36200 the 200A unit. Size to the connected motor or feeder FLA. If the circuit exceeds that range, step up to a larger frame such as a 400A 3-pole K-Frame like the Eaton 6602C72G67.
10) Is an ABB ST200M miniature circuit breaker a smaller version of the same thing?
No. The ABB ST200M is a miniature circuit breaker with a C-curve, listed to UL1077 as a supplementary protector. The Square D JJL PowerPacT J-Frame is a UL Listed molded case breaker built to IEC 60947-2/60947-3 for 600VAC branch and feeder overcurrent protection. UL1077 supplementary protection cannot stand in for branch circuit protection, so the ST200M is not a lighter-duty substitute for a J-Frame.
11) I need a breaker that trips on loss of control voltage - does the Square D JJL do that?
The Square D JJL PowerPacT J-Frame is a thermal magnetic breaker with toggle control and a green trip indicator; its trip response is to overload and short circuit. If the application calls for remote tripping on loss of control power, that function comes from an undervoltage release accessory, such as the Eaton 10250T-GR undervoltage release for NZM series molded case breakers, which is matched to its own breaker family rather than to the J-Frame.
12) Does this breaker need derating at high altitude?
No derating is required up to 2000 m (6561.68 ft). Above that it is derated, with ratings carried to 5000 m, so an installation in high-altitude mountain plant needs the derating factors applied before you size on the 600VAC / 25kA figures.
13) Can I tell at a glance whether this breaker tripped or was switched off?
The JJL uses a toggle handle with a green indicator that shows the switched-off (OFF) condition, so a technician at the panel door can distinguish an intentional OFF from a trip without opening anything.
14) Where is the Square D JJL breaker made, and does it meet Mexican and Canadian approvals?
Built in Mexico, and carrying CSA Certification for Canada plus NOM Certification and NOM-003-SCFI-2000 compliance for Mexico alongside the UL Listing. That covers the three North American jurisdictions on one part number, which matters if you are standardizing a breaker across plants in more than one country.
15) Why do Bussmann CBC and CBF breakers show up next to the Square D JJL, and are they related?
They are a different class of device entirely. The Bussmann CBC series is a Type I automotive circuit breaker rated 14VDC, the CBC-B adds a waterproof stud terminal, and the CBF is a Type II automotive breaker. All are low-voltage DC vehicle and equipment protection. The Square D JJL PowerPacT J-Frame is a 3-pole 600VAC molded case breaker for commercial and industrial distribution panels. Nothing in the Bussmann automotive line substitutes for it.
