Product FAQs
7 answersIs the Square D HJA261504 compatible with older I-Line panelboards?
Yes, Square D has confirmed that PowerPacT H-frame circuit breakers, including the HJA261504, are compatible with both new and existing older I-Line panelboards and switchboards.
Can I replace an older FA or FH frame I-Line breaker with the HJA261504?
Yes, the PowerPacT H-frame is the direct replacement for legacy F-frame I-Line breakers. It fits into the same I-Line panelboard bus structure, though you should verify that the interrupting ratings and phase connections match your application.
What are the phase connections for the HJA261504 circuit breaker?
This specific 2-pole breaker is factory-configured for B and C phase connections in an I-Line panelboard.
Can I convert the HJA261504 I-Line breaker to a unit-mount lug configuration?
No, the I-Line plug-in connector is factory-installed and cannot be removed or retrofitted in the field. If you need a unit-mount configuration with lugs on both ends, you must order a different breaker model.
Is the HJA261504 rated for 100 percent continuous load?
No, this breaker is standard 80 percent rated. Continuous loads should not exceed 80 percent of its 150-amp capacity.
Are the trip settings adjustable on the HJA261504?
This breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous trip functions. It does not have adjustable trip settings like the MicroLogic electronic trip units found on other PowerPacT models.
What does the number 4 at the end of the HJA261504 catalog number indicate?
In the Square D PowerPacT catalog numbering system, the 4 suffix on a 2-pole breaker indicates that it is factory-configured for B and C phase connections.
