Product FAQs
7 answersWhat does the 4 at the end of the HDA261254 catalog number indicate?
The 4 suffix indicates a BC phase connection for the I-Line plug-on jaws. This determines which specific busbars the breaker connects to inside the panelboard.
What does the D in the HDA261254 part number represent?
In the Square D PowerPacT nomenclature, the D indicates the interrupting capacity tier. A D-interrupting rating provides 18kAIC at 480VAC and 25kAIC at 240VAC.
Can the HDA261254 replace older Square D circuit breakers?
Yes, the PowerPacT H-frame is the modern replacement for legacy F-frame I-Line breakers, such as the FA26125 or FH26125. Note that you must match the phase connection and available fault current requirements of your existing installation.
How does this breaker mount into the panel?
The HDA261254 features an I-Line style plug-in connection on the line side. The breaker jaws blow on and grip the panelboard busbars, and the unit is secured with a retaining bracket and screw. The load side uses standard mechanical lugs.
Which panelboards are compatible with the HDA261254?
This breaker is designed exclusively for use in Square D I-Line panelboards and I-Line switchboards. It will not fit in standard QO, Homeline, NQ, or NF load centers.
Is the trip unit on the HDA261254 adjustable?
Yes, this thermal-magnetic breaker features a fixed thermal trip for standard overload protection and an adjustable magnetic trip dial to fine-tune the short-circuit protection response.
Does the HDA261254 include a push-to-trip button?
Yes, PowerPacT H-frame breakers feature an integral push-to-trip button on the front cover. This allows electricians to manually trip the breaker to verify the mechanical operation of the trip mechanism.
