Product FAQs
6 answersCan the HGA260502 replace older F-frame I-Line breakers?
Yes. The PowerPacT H-frame series is the modern replacement for legacy Square D F-frame breakers, including the FA26050 and FH26050. It mounts into the same I-Line panelboards and switchboards.
What does the "G" in the HGA260502 part number signify?
The "G" indicates the breaker's interrupting capacity rating tier. For this PowerPacT H-frame breaker, the G-rating provides 65 kA at 240V AC, 35 kA at 480V AC, and 18 kA at 600V AC.
What does the trailing "2" in the HGA260502 catalog number mean?
The "2" at the end of the part number indicates that the breaker is factory-configured for an AC phase connection on the I-Line bus.
How does the I-Line connection work on this breaker?
The breaker features a plug-on line connection that mounts directly to the I-Line bus in compatible panelboards and switchboards, while the load side utilizes standard mechanical lugs for wire termination.
Is the trip unit on this breaker adjustable?
No. The thermal-magnetic trip unit provides fixed long-time and instantaneous (LI) protection, meaning the trip curve cannot be field-adjusted.
What are the magnetic hold and trip currents for this breaker?
This 50A breaker has a fixed magnetic hold current of 400A and a magnetic tripping current of 850A.
