Product FAQs
8 answersWhat equipment is the PLL34100U44A compatible with?
This unit-mount P-frame breaker is designed for installation in Square D QED switchboards, Model 6 Motor Control Centers, and compatible I-Line panelboards configured for unit-mount breakers.
What do the letters in the PLL prefix indicate?
The P denotes the PowerPacT P-frame. The first L indicates the high interrupting rating, providing 100 kA at 480 VAC. The second L specifies the termination type, meaning the breaker is factory-supplied with lugs on both the line and load ends.
What features are included with the U44A trip unit designation?
The U44A suffix indicates a MicroLogic 6.0A electronic trip unit. This provides adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault (LSIG) protection, plus an integrated ammeter for local current monitoring.
What wire sizes are accepted by the standard lugs on the PLL34100U44A?
The factory-installed lugs accommodate four 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
Does this breaker plug directly onto an I-Line bus?
No. The PLL34100U44A is a unit-mount, feed-thru breaker equipped with lugs on both the line and load sides. It does not have the plug-on jaw connections used for direct I-Line bus mounting.
Can the MicroLogic trip unit be changed in the field?
Yes. PowerPacT P-frame breakers feature interchangeable MicroLogic trip units, allowing you to upgrade protection functions or add communication modules without replacing the entire breaker frame.
Is the PLL34100U44A rated for 100 percent continuous current?
No, this specific catalog number is standard-rated for 80 percent continuous current. A "C" suffix in the catalog number is required for a 100 percent continuous rating.
How can I manually test the mechanical tripping mechanism?
The breaker features an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker to verify that the mechanical linkage is operating correctly.
