Product FAQs
8 answersCan the HDA260804 replace older Square D circuit breakers?
Yes, the PowerPacT H-Frame is the direct manufacturer replacement for obsolete F-Frame I-Line breakers. Specifically, the HDA260804 replaces the legacy FA26080BC circuit breaker.
What do the letters "HDA" signify in the HDA260804 catalog number?
"H" indicates the PowerPacT H-Frame family. "D" specifies the standard interrupting rating tier, which provides 18 kAIC at 480 VAC. "A" denotes an I-Line style termination, meaning it plugs directly onto the panelboard bus on the line side.
What does the "4" suffix indicate on this circuit breaker?
The "4" at the end of the catalog number indicates that this 2-pole I-Line breaker is factory-configured for a BC phase connection on the panelboard bus.
Will this breaker fit in a standard Square D NQ or NF panelboard?
No, the HDA260804 features an I-Line plug-on connection. It is only compatible with Square D I-Line power distribution panelboards and switchboards, not NQ, NF, QO, or Homeline load centers.
What wire sizes are supported by the load lugs?
The factory-installed mechanical lugs on this 80A breaker accept either copper or aluminum conductors ranging from 14 AWG to 3/0 AWG.
Are the trip settings adjustable on the HDA260804?
No, this breaker is equipped with a standard thermal-magnetic trip unit featuring fixed long-time and fixed instantaneous (LI) trip functions. It does not offer adjustable trip dials.
How is the HDA260804 secured inside the panelboard?
The line side of the breaker plugs directly onto the I-Line bus stack. The load side (the "OFF" end) is secured to the panelboard backpan using a captive mounting screw.
Is the HDA260804 suitable for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment group motor installations.
