Product FAQs
7 answersWhat panelboards and switchboards are compatible with the PGA36100U43A?
This breaker is designed for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection for quick and standardized installation.
Can I use the PGA36100U43A in a standard unit-mount application?
No, the PGA36100U43A features an I-Line plug-in connection on the line side. For a unit-mount application with lugs on both the line and load sides, you will need the PGL36100U43A.
What does the U43A suffix indicate on this circuit breaker?
The U43A suffix indicates that the breaker is equipped with a Micrologic 5.0A electronic trip unit. This provides adjustable Long-Time, Short-Time, and Instantaneous (LSI) protection, along with an integrated ammeter for current measurement.
What wire sizes are accepted by the lugs on the PGA36100U43A?
The factory-installed load-side lugs accept four 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
Does the PGA36100U43A include a push-to-trip feature?
Yes, like all PowerPacT circuit breakers, it features an integral push-to-trip button on the cover. This allows you to manually trip the breaker to verify the mechanical operation of the tripping mechanism.
Is the PGA36100U43A rated for 100 percent continuous current?
No, this standard breaker is rated for 80 percent continuous loading. For a 100 percent continuous current rating, a different catalog number with a C suffix, such as PGA36100CU43A, would be required.
Can the Micrologic 5.0A trip unit on the PGA36100U43A be interchanged in the field?
Yes, PowerPacT P-Frame breakers equipped with Micrologic trip units are designed to be field-interchangeable. This allows for maximum flexibility if your protection or metering requirements change.
