Product FAQs
8 answersWhat does the U43X suffix indicate on the HDL36100U43X?
The U43X suffix specifies that the breaker is equipped with a Micrologic 5.2 A electronic trip unit. This provides adjustable Long-time, Short-time, and Instantaneous (LSI) overcurrent protection, along with an integrated ammeter for current monitoring.
Does the HDL36100U43X provide equipment ground fault protection?
No, this breaker features LSI (Long-time, Short-time, Instantaneous) protection. For equipment ground fault protection (LSIG), you would need a breaker with a Micrologic 6.2 A trip unit, typically denoted by a U44X suffix.
Is the HDL36100U43X 100% rated for continuous current?
No, this specific catalog number is standard 80% rated. Square D PowerPacT breakers that are 100% rated include a "C" suffix at the end of the part number.
Can I install the HDL36100U43X in an I-Line switchboard?
No, this specific breaker is a unit-mount (lug-to-lug) model designed for feed-thru applications. To install a 100A H-frame breaker with a Micrologic 5.2 A trip unit in an I-Line panel, you would need the I-Line version, catalog number HDA36100U43X.
What is the difference between the HDL36100U43X and the HGL36100U43X?
The difference lies in the interrupting rating. The HDL model has a "D" interrupting rating (18 kA at 480VAC), while the HGL model features a higher "G" interrupting rating (35 kA at 480VAC). Both share the same 100A frame and Micrologic 5.2 A trip unit.
How is the HDL36100U43X mounted in a panel?
This breaker features a unit-mount configuration, indicated by the "L" in the third position of the part number. It uses lugs on both the line and load sides for direct wire connections and is typically secured with mounting screws, rather than plugging into a busway.
Are the trip settings adjustable on the HDL36100U43X?
Yes, the Micrologic 5.2 A electronic trip unit allows for precise adjustments of the Long-time, Short-time, and Instantaneous (LSI) pickup and delay settings to ensure proper selective coordination in your electrical system.
Does the HDL36100U43X include an LCD display?
Yes, the Micrologic 5.2 A trip unit features an integrated LCD screen to display current measurements and allow for fine adjustment of trip settings.
