Product FAQs
9 answersWhat does the 4 at the end of the HGA261004 catalog number indicate?
The 4 suffix indicates a factory-configured BC phase connection. This 2-pole breaker is designed to plug specifically into the B and C phases on the busbar of a Square D I-Line panelboard.
Why does the HGA261004 specify a BC phase connection?
In a 3-phase I-Line panelboard, a 2-pole breaker only connects to two of the three busbars. The BC configuration ensures the breaker draws power specifically from the B and C phases, which is critical for balancing electrical loads across the panel.
Which panelboards are compatible with the HGA261004 circuit breaker?
This PowerPacT H-frame breaker features an I-Line plug-on design, making it compatible exclusively with Square D I-Line panelboards and switchboards. It cannot be installed in standard NQ or NF load centers.
What does the G in the HGA261004 part number represent?
The G indicates the interrupting rating tier for this PowerPacT H-frame breaker. It signifies a short-circuit current rating of 65kAIC at 240VAC, 35kAIC at 480VAC, and 18kAIC at 600VAC.
Can the HGA261004 be used in DC voltage applications?
Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, where it provides a 20kA interrupting capacity for industrial control and battery circuits.
How does the HGA261004 mount into the panel?
It utilizes the Square D I-Line plug-on mounting system. The line side plugs directly into the panelboard bus assembly, while the load side uses traditional mechanical lugs for wire termination.
What wire sizes are accepted by the load-side lugs on the HGA261004?
The factory-installed AL150HD lugs accept aluminum or copper conductors ranging from 14 AWG to 3/0 AWG.
Can the HGA261004 replace older Square D FA or FH series breakers?
Yes, the PowerPacT H-frame I-Line breakers are the direct modern replacements for discontinued 100A FA and FH series I-Line breakers, such as the FA26100BC or FH26100BC. They fit into the exact same panelboard space without requiring busbar modifications.
Is the trip unit on the HGA261004 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit with Long-Time and Instantaneous functions. The instantaneous magnetic trip is factory-set with a hold current of 900A and a trip current of 1700A.
