Product FAQs
6 answersWhat type of panelboards accept the HGA260454 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on line connection that ratchets directly onto the I-Line bus stack, eliminating the need for separate bus connectors.
What does the 4 suffix indicate in the HGA260454 catalog number?
The 4 at the end of the part number specifies a BC phase connection for the I-Line bus. Other suffixes indicate different phase configurations, such as 1 for AB or 2 for AC.
Can the HGA260454 replace older Square D I-Line breakers?
Yes, PowerPacT H-frame breakers like the HGA260454 are the direct replacements for obsolete F-frame I-Line breakers, including the FA and FH series. They fit into the same I-Line panelboard bus structure.
What lug kit is standard on the load side of this breaker?
The standard mechanical lug kit for 15A to 150A PowerPacT H-frame breakers is the AL150HD. It accepts 14 AWG to 3/0 AWG aluminum or copper wire.
What does the G stand for in the HGA frame designation?
The G indicates the interrupting rating tier of the breaker. For this model, it provides 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
Can I adjust the trip curve on the HGA260454?
No. This breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions. It does not have adjustable dials for the trip curve.
