Product FAQs
7 answersCan the HJA261001 replace older F-Frame I-Line circuit breakers?
Yes. The PowerPacT H-Frame occupies the same I-Line mounting space as discontinued F-Frame breakers, making it a direct plug-on replacement for older FA, FH, and FC series I-Line breakers.
What does the J in the HJA261001 part number signify?
The J indicates the interrupting rating tier for this PowerPacT breaker. It provides 100 kA at 240V, 65 kA at 480V, and 25 kA at 600V.
What wire sizes and materials are accepted by the load side lugs?
The factory-installed mechanical lugs accept either aluminum or copper conductors ranging from 14 AWG to 3/0 AWG.
Does this breaker require a separate mounting bracket for installation?
No. As an I-Line style plug-in breaker, it features plug-on jaws on the line side that seat directly onto the panelboard bus, requiring no additional mounting hardware or bus work.
Can the HJA261001 be used in standard unit-mount applications?
No. This breaker features an I-Line plug-in connection on the line side and is designed exclusively for Square D I-Line panelboards and switchboards.
How can I visually verify if the HJA261001 has tripped?
This breaker features a Visi-Trip indicator that provides a clear visual flag when the breaker has tripped due to an overcurrent or short circuit event.
What type of contacts are used inside this PowerPacT H-Frame breaker?
It is equipped with dual-break rotating contacts that reduce the amount of peak let-through current during a short circuit fault, protecting downstream equipment.
