Product FAQs
8 answersWhich legacy Square D breakers does the HGA260901 replace?
The PowerPacT H-frame HGA260901 is the direct, modern replacement for discontinued F-frame breakers, specifically the FA26090AB and FH26090AB I-Line models.
What does the 1 suffix in the HGA260901 catalog number mean?
The 1 at the end of the part number indicates an AB phase connection. When installed in an I-Line panelboard, the breaker's line-side jaws will connect specifically to the A and B phases of the busbar.
How is the HGA260901 installed in a panelboard?
It utilizes an I-Line plug-on connection for the line side, where the jaws snap directly onto the panelboard bus and a built-in bracket screws into the backpan for secure mounting. The load side uses standard mechanical lugs for wire termination.
How does the trip unit on the HGA260901 operate?
It features a thermal-magnetic trip unit that provides fixed thermal protection for long-time overloads and an adjustable magnetic dial to fine-tune the instantaneous short-circuit trip threshold.
What does the G in the HGA260901 part number signify?
The G designates the interrupting rating tier within the PowerPacT H-frame family, indicating a standard-high breaking capacity that sits above the base D tier and below the higher-rated J and L tiers.
Can the HGA260901 be used as a back-fed main breaker?
Yes, this breaker is rated for reverse-fed applications. Because it is an I-Line breaker, its built-in mounting bracket and retaining screw inherently secure it to the panelboard, satisfying the NEC requirement for fastening back-fed mains without needing an additional hold-down kit.
Is the HGA260901 HACR rated?
Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires specialized motor-circuit protection.
What is the maximum frame size for the HGA260901?
It is built on the Square D PowerPacT H-frame, which has a maximum capacity of 150 amps, though this specific breaker is factory-calibrated for a 90-amp continuous load.
