Product FAQs
5 answersWhat does the "4" suffix in the HJA260204 catalog number indicate?
The "4" suffix specifies that this 2-pole breaker is configured for a BC phase connection on the I-Line bus. Standard 2-pole I-Line breakers without a suffix or with a "1" suffix are typically configured for an AB phase connection.
Can the PowerPacT H-Frame HJA260204 replace older F-Frame I-Line breakers?
Yes, PowerPacT H-Frame breakers are the current replacement for legacy Square D F-Frame (FA, FH, FC, FI) I-Line breakers. They mount in the same I-Line bus space, though the physical footprint and lug placement may differ slightly.
What conductor materials are supported by the standard lugs on this breaker?
The standard factory-installed lugs are dual-rated for both aluminum and copper conductors, accepting wire sizes from 14 AWG to 3/0 AWG.
How does this breaker connect to the panelboard bus?
It utilizes a blow-on plug-on connection designed exclusively for Square D I-Line panelboards and switchboards. The breaker jaws mount directly to the I-Line bus stack, and the connection grips tighter under high-level short circuit conditions.
Is the HJA260204 considered a current-limiting circuit breaker?
Yes, PowerPacT H-Frame breakers with the J interrupting rating are UL Listed and CSA Certified as current-limiting circuit breakers. They are designed to reduce peak let-through energy during a short circuit fault.
