Product FAQs
8 answersWhich panelboards accept the HJA260801 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. Its plug-in bracket mounting allows it to snap directly onto the I-Line bus system.
What does the 1 at the end of the HJA260801 catalog number indicate?
The 1 suffix specifies that this 2-pole breaker is configured for an AB phase connection on the I-Line bus. If you need a different phase arrangement, you will need a different catalog number suffix.
Can I use both aluminum and copper conductors with this breaker?
Yes, the standard lugs on this PowerPacT H-frame breaker are dual-rated for both aluminum and copper conductors. Ensure you use an appropriate antioxidant compound when terminating aluminum wire.
How does the line side of this breaker connect to the panel?
The line side features an I-Line plug-in bracket that snaps directly onto the panelboard bus, while the load side uses standard mechanical lugs for wire termination.
Does this breaker provide both overload and short-circuit protection?
Yes, it features a thermal-magnetic trip unit that includes both long-time (thermal) and instantaneous (magnetic) trip functions to protect against overloads and short circuits.
Is the HJA260801 rated for use in DC applications?
Yes, in addition to its 600VAC rating, this PowerPacT H-frame breaker is rated for up to 250VDC.
Is this breaker rated for 80% or 100% continuous current?
The HJA260801 is a standard-rated breaker, meaning it is rated for 80% continuous current.
Can the HJA260801 replace older Square D breakers?
Yes, the PowerPacT H-frame I-Line breakers are the direct replacements for legacy Square D F-frame (such as FA and FH) I-Line circuit breakers of the same amperage and pole configuration.
