Built to handle demanding electrical systems, the Square D HGA260804 is a 2-pole, 80A molded case circuit breaker. As part of the PowerPacT H-frame series, it provides thermal-magnetic protection with long-time and instantaneous (LI) functions. This breaker mounts into Square D I-Line panelboards and switchboards. It is an exact replacement for older FA26080BC and FH26080BC models. It features a BC phase connection, current-limiting capabilities, and a 35kAIC interrupting rating at 480VAC.
What does the "4" suffix in the HGA260804 catalog number indicate?
The "4" suffix specifies that this 2-pole breaker is configured for a BC phase connection on the I-Line bus.
Can the PowerPacT HGA260804 replace older Square D F-frame breakers?
Yes, the PowerPacT H-frame is the direct manufacturer upgrade for legacy Square D F-frame I-Line breakers, such as the FA and FH series. The HGA260804 will fit into the same I-Line panelboards and switchboards.
What interrupting rating tier does the "G" in HGA260804 represent?
The "G" designates Square D's intermediate interrupting capacity tier for the PowerPacT series. It provides a step up from the base D-tier rating, delivering 65kA at 240VAC and 35kA at 480VAC.
Is the HGA260804 suitable for reverse-fed applications?
Yes, this thermal-magnetic circuit breaker is approved for reverse-fed installations, allowing it to be back-fed within compatible I-Line panelboards.
How is the HGA260804 physically installed into the electrical panel?
The breaker features an "A" termination configuration. The line side plugs directly into an I-Line bus using a jaw-style connection, while the load side utilizes mechanical lugs that accept 14 AWG to 3/0 AWG aluminum or copper conductors.
Are the trip settings field-adjustable on the HGA260804?
No, this breaker is equipped with a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without adjustable dials.
Will the HGA260804 fit in a standard QO or Homeline load center?
No, the HGA260804 is an H-frame molded case circuit breaker designed exclusively for Square D I-Line panelboards and switchboards. It is not compatible with residential load centers.
Does the HGA260804 provide equipment ground-fault protection?
No, this is a standard thermal-magnetic breaker providing only overload and short-circuit protection. It does not include ground-fault (GFPE or GFCI) or arc-fault circuitry.
