Product FAQs
9 answersWhat equipment is the Square D PGL36100 designed to be installed in?
This P-frame breaker is designed for use in switchboards, motor control centers, and individual enclosures. It is a unit mount breaker, meaning it bolts directly to the mounting surface rather than plugging into a busbar.
What does the G in the PGL36100 catalog number signify?
The G indicates the interrupting rating tier within the PowerPacT P-frame series. For this breaker, it provides 65kA at 240V AC, 35kA at 480V AC, and 18kA at 600V AC.
What does the L in the PGL prefix indicate?
The L specifies that this is a unit mount breaker equipped with mechanical lugs on both the line and load sides.
Can the PGL36100 be used in an I-Line panelboard?
No. The PGL36100 is a unit mount breaker designed for feed-thru applications. It is not designed to plug into an I-Line bussing system. For I-Line applications, you would need the PGA36100.
What wire sizes are compatible with the lugs on the PGL36100?
The included lugs accept four wires per phase, ranging from 3/0 AWG to 500 kcmil. They are compatible with both aluminum and copper conductors.
What does the LI trip function code mean on this breaker?
The LI indicates that the electronic trip unit provides Long-Time (L) and Instantaneous (I) protection. This combination protects against both gradual overloads and sudden short circuits.
Is the trip unit on the PGL36100 adjustable?
Yes, the ET 1.0I electronic trip unit features a fixed thermal (Long-Time) setting and an adjustable magnetic (Instantaneous) setting, allowing you to fine-tune the short circuit protection.
Is the PGL36100 a direct replacement for older Square D breakers?
Yes, this PowerPacT P-frame breaker serves as a modernized, direct drop-in replacement for the legacy MAL361000 series unit mount breakers.
How does the ET 1.0I trip unit protect my electrical system?
The ET 1.0I is an electronic trip unit that uses microprocessor-based true RMS sensing to monitor current. It provides highly accurate Long-Time (overload) and Instantaneous (short circuit) protection, ensuring reliable defense against electrical faults.
