Product FAQs
7 answers
What do the letters in the PKL36100 catalog number indicate?
In the PowerPacT nomenclature, P stands for the P-frame size, K indicates the interrupting rating tier (65kA at 240V, 50kA at 480V, 50kA at 600V), and L means it is equipped with lugs on both the line and load ends.
Which electrical systems are compatible with the PKL36100 circuit breaker?
This unit mount breaker is designed for use in Square D QED switchboards, Model 6 motor control centers, and individual enclosures. It is not compatible with I-Line panelboards.
What wire size and material can be used with the lugs on the PKL36100?
The factory-installed lugs accept four 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
What type of trip unit is installed in the PKL36100?
It features a basic electronic trip unit with LI functions, providing fixed long-time protection and adjustable instantaneous protection.
What is the difference between the PKL36100 and the PGL36100 or PJL36100?
The difference is the interrupting rating. The PKL36100 has a K rating (50kA at 480V), while the PGL36100 has a G rating (35kA at 480V) and the PJL36100 has a J rating (65kA at 480V). They share the same physical dimensions and mounting.
Is the PKL36100 an I-Line or unit mount breaker?
The PKL36100 is a unit mount, feed-thru circuit breaker with lugs on both ends. If you need the I-Line plug-on equivalent for a panelboard, you will need a different catalog number, such as PKA36100.
Is the PKL36100 rated for 100 percent continuous load?
No, the standard PKL36100 is rated for 80 percent continuous load. PowerPacT P-frame breakers require a C in the catalog number to indicate a 100 percent rating.
