Square D JDL PowerPacT J 3-Pole Circuit Breaker, 600VAC Thermal Magnetic

The Square D PowerPacT J 3-Pole Circuit Breaker (JDL) is a J-Frame molded-case breaker built to protect electrical systems from overloads and short circuits. This family is available with a Motor FLA rating from 175A to 250A, giving panel builders and electricians a single breaker platform that scales to the connected motor load. Every option in the family shares the same core design: 600VAC rated operation, thermal magnetic trip protection, an 80% rated continuous current design, a 14kA interrupt rating, and line/load lug terminations for a solid, code-compliant connection. Ideal for commercial and industrial distribution equipment requiring dependable overcurrent protection across a range of motor feeder sizes.

Key Features

  • Motor FLA Range: Available from 175A to 250A to match the connected motor full-load amperage.
  • Poles: 3-pole configuration for three-phase distribution circuits.
  • Voltage Rating: 600VAC rated operational voltage (Ue) per IEC 60947-3, constant across the family.

Square D JDL36175 – Frequently Asked Questions

1) What amp ratings does the Square D JDL PowerPacT J 3-pole breaker come in?
Two ratings are built on the JDL J-frame: JDL36175 at 175A motor FLA and JDL36250 at 250A. Both are 3-pole, 600VAC, thermal magnetic, with a 14kA interrupt rating, so the only thing changing between them is the trip rating matched to the connected motor full-load amperage.
2) Is 14kA enough interrupt rating for my panel, and can I use this JDL breaker on a 480V three-phase feeder?
The JDL is rated 600VAC, so 480V and 600V three-phase feeders are both within its rating. Its breaking capacity is 14kA, which is the figure to compare against the available fault current at the point of installation. If your short-circuit study shows more than 14kA at that bus, this breaker is not the right choice and you need a higher-AIC J-frame or a series-rated combination.
3) What wire size do the lugs on the Square D JDL breaker accept?
Line and load lugs are supplied on the breaker and take AWG 4 through AWG 4/0, aluminum or copper. That covers typical 175A and 250A feeder conductors. If your design calls for parallel runs larger than 4/0 per pole, or for a bus connection instead of cable, the lug version is the wrong termination.
4) Is the Square D JDL breaker approved for HVAC equipment branch circuits?
It is marked for HACR circuit breaker application, which is what inspectors look for on multi-motor and combination-load HVAC equipment. It is also UL Listed, CSA Certified, NOM Certified, CE marked, and compliant with IEC 60947-2.
5) What is the closest cross-brand alternative to a Square D JDL PowerPacT J 3-pole molded case breaker?
The Square D JDL is a 3-pole molded case breaker rated 600VAC with lug line and load terminations and a 175A to 250A motor FLA range. The nearest cross-brand items in the same construction class are the ABB A2A150TT, a 3-pole molded case breaker in the A2 series, and the ABB XT5 3-pole circuit breaker kit. Both are 3-pole molded case designs rather than plug-on branch breakers, so they address the same type of feeder and distribution duty.
6) Can an Eaton BAB Quicklag breaker be used in place of a Square D JDL J-frame breaker?
No. The Eaton BAB Quicklag three-pole breaker is a 240V thermal-magnetic branch breaker, and the BAB series bolt-on version mounts to a panel bus rather than terminating on lugs. The Square D JDL is a 600VAC molded case breaker with line and load lugs covering 175A to 250A motor FLA, so it serves feeder-size three-phase circuits that fall outside the BAB's 240V branch application.
7) If the circuit needs more than 250A, what should be used instead of the Square D JDL?
The Square D JDL PowerPacT J family tops out at a 250A motor FLA rating. For a larger three-phase feeder, the Eaton Series C K-frame mining circuit breaker is a 400A 3-pole molded case breaker with an interchangeable rating plug, which steps above the J-frame range. The ABB XT5 3-pole breaker kit is another larger-frame molded case option.
8) Will a PowerPacT J-frame breaker fit the space I have in the enclosure?
The 3-pole JDL measures 7.52 x 4.09 x 3.39 inches (height, width, depth), so plan the pocket and gutter space around that plus bending room for 4/0 cable at the lugs.
9) Thermal magnetic or electronic trip for a motor feeder in this size range?
The JDL uses a thermal magnetic trip unit, which handles overload and short circuit protection with fixed characteristics and no setup. That is the straightforward pick for a motor feeder where the load is known and you want nothing to configure in the field. If you need adjustable long-time, short-time, or ground-fault settings to coordinate with downstream devices, an electronic trip J-frame is the one to spec instead.
10) What else does ZenSupply carry if the Square D J-frame does not suit the panel?
Other molded case options include the ABB A2A150TT in the A2 Series, 3-pole, and the ABB XT4 and XT5 3-pole breaker kits (MBB33 and MBM334). For smaller branch circuits rather than a 175-250A feeder, the Eaton BAB Quicklag 3-pole thermal magnetic breaker is a 240V bolt-on device, not a 600V J-frame substitute. Matching a Square D panelboard interior still means staying with the Square D J-frame.
11) Is an ABB ST200M miniature circuit breaker an alternative to the Square D JDL?
They serve different roles. The ABB ST200M is a C-curve miniature circuit breaker built to UL1077, which covers supplementary protectors used inside equipment. The Square D JDL is a UL Listed molded case breaker rated 600VAC with a 175A to 250A motor FLA range for branch and feeder overcurrent protection in distribution equipment, so the ST200M does not replace it.
12) What is the operating temperature range for the PowerPacT J breaker in an unconditioned mechanical room?
Rated for ambient air from -25 to 70 degrees C. That covers unheated mechanical rooms and hot interior switchgear rooms, though remember the thermal element responds to ambient, so at the high end a heavily loaded breaker will trip earlier than at 40 C.
13) How do I tell at a glance whether this breaker tripped or was switched off?
The JDL is toggle operated with local ON/OFF/trip indication, including a green trip indicator, so a maintenance tech can distinguish a tripped breaker from one opened manually without pulling the deadfront.
14) Does the Square D JDL accept an undervoltage release like the Eaton NZM breakers?
The Square D JDL PowerPacT J is a toggle-operated thermal magnetic molded case breaker with local ON/OFF and trip indication, ordered as a complete device. The Eaton 10250T-GR is a separate undervoltage release accessory for Eaton NZM series molded case breakers, so it belongs to that frame family and is not an accessory specified with the JDL.
