Product FAQs
5 answersWhat does the "1" at the end of the HDA260901 catalog number indicate?
The "1" suffix specifies that the breaker is configured for an AB phase connection on the I-Line bus. Other suffixes, such as 2 or 3, represent different phase connections like AC or BA.
What does the "D" in the HDA260901 part number signify?
The "D" indicates the interrupting rating performance level of the breaker. For this PowerPacT H-Frame model, the D-rating provides an 18kAIC capacity at 480VAC and 25kAIC at 240VAC.
What does the "A" in the HDA prefix stand for?
The "A" indicates the termination type. In the Square D PowerPacT nomenclature, "A" specifies an I-Line style plug-in connection on the line side and mechanical lugs on the load side.
Does the HDA260901 replace any older Square D breakers?
Yes, this PowerPacT H-frame breaker is the direct replacement for the legacy FA26090 and FA26090AB molded case circuit breakers.
How does the I-Line connection work on the HDA260901?
The breaker uses a plug-on design for the line side that snaps directly onto the I-Line bus, while the load side uses standard mechanical lugs for wire termination. This allows for rapid installation in I-Line panelboards without bolted line connections.
