Product FAQs
9 answersWhat does the U33A suffix mean on this Square D circuit breaker?
The U33A suffix indicates that the breaker is equipped with a Micrologic 5.0 electronic trip unit. This standard trip unit provides adjustable Long-Time, Short-Time, and Instantaneous (LSI) protection settings.
Does the PJL36080U33A provide ground-fault protection?
No, the included Micrologic 5.0 trip unit provides Long-Time, Short-Time, and Instantaneous (LSI) protection only. It does not include integral equipment ground-fault (LSIG) protection, which would require upgrading to a Micrologic 6.0 trip unit.
What type of mounting does the Square D PJL36080U33A use?
This model features a unit-mount configuration, meaning it mounts individually using brackets or baseplates. It connects to the system using standard mechanical lugs on both the line and load sides.
Can the PJL36080U33A be installed in a Square D I-Line panelboard?
No, the PJL36080U33A is a unit-mount circuit breaker equipped with mechanical lugs on both ends. It does not have the plug-on jaw connections required to install into an I-Line panelboard.
What type of switchboards or enclosures accept the PJL36080U33A?
This breaker is compatible with Square D QED switchboards, motor control centers, and standalone PowerPacT P-frame enclosures designed specifically for unit-mounted breakers.
Is the trip unit on the PJL36080U33A adjustable?
Yes, the included Micrologic 5.0 electronic trip unit allows for precise adjustments. You can modify the Long-Time, Short-Time, and Instantaneous (LSI) trip settings to coordinate with your specific system coordination requirements.
Can I use aluminum wiring with the PJL36080U33A breaker?
Yes, the factory-installed mechanical lugs are dual-rated for both aluminum and copper conductors. They accept three wires per phase, ranging from 3/0 AWG to 500 kcmil.
Can the trip unit on the PJL36080U33A be replaced or upgraded?
Yes, the PowerPacT P-frame design allows for field-interchangeable trip units. If your protection requirements change, you can upgrade from the standard Micrologic 5.0 to other compatible Micrologic trip units without replacing the entire breaker frame.
Is the PJL36080U33A rated for 100% continuous duty?
No, this breaker is standard-rated for 80% continuous current. For a 100% continuous duty rating, you would need the version with the C suffix in the catalog number, such as PJL36080CU33A.
