Product FAQs
9 answersWhat are the magnetic trip thresholds for the JDL36150?
This 150A breaker has a magnetic hold current of 750A and a magnetic tripping current of 1500A. These instantaneous trip settings are designed to clear short-circuit faults quickly while allowing normal inrush currents from motors and transformers without nuisance tripping.
What is the difference between the JDL36150 and the JGL36150?
Both are 150-amp, 3-pole PowerPacT J-frame breakers, but they have different interrupting capacities. The JDL36150 features a D-interrupting rating (14kA at 600VAC), while the JGL36150 features a G-interrupting rating for higher fault current applications (18kA at 600VAC).
Is the JDL36150 suitable for reverse-feed applications?
Yes. PowerPacT J-frame circuit breakers equipped with thermal-magnetic trip units are factory-sealed and fully suitable for reverse connection.
What is the I-Line equivalent for this unit-mount breaker?
If you are installing into a Square D I-Line panelboard or switchboard, you will need the I-Line version of this breaker, which is catalog number JDA36150. The JDL36150 is strictly for unit-mount installations using mechanical lugs.
Can I field-install auxiliary accessories in this J-frame breaker?
Yes. The PowerPacT J-frame accommodates field-installable plug-in accessories, including auxiliary switches (OF), alarm switches (SD), overcurrent trip switches (SDE), shunt trips (MX), and undervoltage releases (MN). These snap securely into designated accessory compartments behind the front cover.
What type of lugs are standard on this J-frame breaker?
The JDL36150 comes factory-equipped with mechanical lugs (part number AL175JD) on both the line and load sides. These dual-rated aluminum and copper lugs accept wire sizes from 4 AWG up to 4/0 AWG.
What does the 80% continuous current rating mean for this breaker?
Like most standard molded case circuit breakers, the JDL36150 is 80% rated. This means that continuous loads (those lasting 3 hours or more) should not exceed 120 amps, which is 80% of its 150A maximum rating.
What is the tightening torque for the wire terminals on the JDL36150?
For the standard AL175JD lugs, the manufacturer specifies a tightening torque of approximately 221 to 230 lb-in (25 to 26 N.m). Always verify the exact torque requirement printed on the breaker label to ensure a safe and compliant connection.
Can I swap or upgrade the trip unit on the JDL36150?
No. This breaker features a factory-sealed thermal-magnetic trip unit. If you require advanced electronic protection or adjustable trip characteristics, you must select a different PowerPacT J-frame model equipped with a Micrologic trip unit.
