This unit-mount breaker is commonly used in Square D QED switchboards, Model 6 motor control centers, and individual enclosures.
What protection functions are included with the ET 1.0I trip unit on this breaker?
The ET 1.0I is a basic electronic trip unit that provides Long-Time (L) and Instantaneous (I) protection. Long-time protects against overloads, while instantaneous protects against short circuits.
What wire sizes are compatible with the lugs on the PGL36060?
The included line and load lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
What does the "G" in the PGL36060 catalog number indicate?
The "G" designates the interrupting rating tier. For this breaker, it provides 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
What does the "L" in the PGL36060 part number stand for?
The "L" indicates the termination type. It means the breaker is configured for unit mounting with mechanical lugs on both the line and load ends.
