Product FAQs
9 answersWhat panelboards are compatible with the HDA36060U31X?
This breaker is designed for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection on the line side and mechanical lugs on the load side.
Can I use this breaker to replace an older Square D F-frame I-Line breaker?
While it can replace legacy F-frame I-Line breakers of the same amperage and voltage, the PowerPacT H-frame dimensions and mounting footprint may differ. Verify your panel's physical space and busbar configuration before upgrading.
What does the U31X suffix indicate on this breaker?
The U31X suffix designates that the breaker is equipped with a Micrologic 3.2 electronic trip unit, which provides adjustable Long-Time and Instantaneous (LI) protection functions.
What does the D in the HDA36060U31X catalog number mean?
The D indicates the interrupting rating tier within the PowerPacT H-frame family. It signifies a standard interrupting capacity of 25kA at 240VAC, 18kA at 480VAC, and 14kA at 600VAC.
How does the I-Line connection work on the HDA36060U31X?
The I-Line connection features plug-on jaws on the line side that snap directly onto the busbar of an I-Line panelboard or switchboard, while the load side utilizes standard mechanical lugs for wire termination.
Can the trip settings be adjusted on this breaker?
Yes, the Micrologic 3.2 electronic trip unit allows for adjustable Long-Time and Instantaneous (LI) pickup settings, enabling precise coordination with other protective devices in your electrical system.
What is the difference between the HDA36060U31X and the HGA36060U31X?
The difference lies in the interrupting rating. The HDA has a D interrupting rating (18kA at 480VAC), while the HGA features a higher G interrupting rating (35kA at 480VAC). Both share the same 60A rating, I-Line mounting, and Micrologic 3.2 trip unit.
Is there a higher interrupting rating available for this exact configuration?
Yes, if your system requires a higher fault current rating, you can step up to the HGA36060U31X (35kA at 480VAC), HJA36060U31X (65kA at 480VAC), or HLA36060U31X (100kA at 480VAC).
Does the HDA36060U31X provide ground fault protection?
No, the U31X suffix indicates a Micrologic 3.2 trip unit, which only provides Long-Time and Instantaneous (LI) protection. It does not include Ground Fault (G) or Short-Time (S) protection.
