Product FAQs
8 answersWhat does the "C" in the PGL36080CU31A catalog number indicate?
The "C" indicates that this breaker is 100% rated. This means it can carry its full 800A continuous current rating without the standard 80% derating, provided it is installed in a properly sized enclosure using 90 degree Celsius wire sized to the 75 degree Celsius ampacity.
What type of trip unit is included with the PGL36080CU31A?
The "U31A" suffix indicates it is equipped with a MicroLogic 3.0 electronic trip unit. This provides adjustable Long-Time and Instantaneous (LI) protection functions.
What equipment is this breaker designed to be installed in?
This unit-mount P-frame breaker is designed for use in Square D QED switchboards, Model 6 motor control centers, and individual P-frame enclosures.
What size wire can the lugs on this breaker accommodate?
The standard mechanical lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
Can the MicroLogic trip unit be swapped out in the field?
Yes, PowerPacT P-frame breakers feature interchangeable MicroLogic trip units. This allows you to upgrade to advanced models with LSI or LSIG functions, or add power metering capabilities, without replacing the entire breaker frame.
Does this breaker have a push-to-trip feature?
Yes, all PowerPacT P-frame circuit breakers include an integral push-to-trip button on the cover to manually trip the breaker for testing and maintenance.
Is this an I-Line or unit-mount breaker?
The "L" in the PGL prefix indicates this is a unit-mount (bolt-on) breaker with lugs on both the line and load sides, rather than an I-Line plug-on configuration.
What does the "G" in the PGL prefix stand for?
The "G" designates the interrupting rating tier for this PowerPacT P-frame breaker. It provides 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
