Product FAQs
6 answersCan the HJA260901 be installed in older Square D I-Line panelboards?
Yes, Square D PowerPacT H-frame circuit breakers are backward compatible with existing and older I-Line panelboards and switchboards, provided the voltage and interrupting ratings meet your system requirements.
Can this PowerPacT H-frame breaker replace older F-frame breakers?
Yes, the HJA260901 can replace obsolete 90-amp F-frame I-Line circuit breakers, such as the FA or FH series. Always verify that the 600VAC and 25kAIC ratings meet or exceed your original breaker's specifications before upgrading.
What is the phase connection for the HJA260901 circuit breaker?
This specific catalog number is factory configured for an AB phase connection on the I-Line bus. If you need a different phase configuration, you will need a different catalog number, such as HJA260902 for an AC phase connection.
How is the HJA260901 wired and mounted?
This breaker features an I-Line style plug-in connection on the line side that mounts directly onto the panelboard bus. The load side uses mechanical lugs that accept 14 AWG to 3/0 AWG aluminum or copper wire.
What are the interrupting ratings for this breaker at 240V and 480V?
In addition to its 25kAIC rating at 600VAC, the J-interrupting tier of this PowerPacT breaker provides 65kAIC at 480VAC and 100kAIC at 240VAC.
Is the HJA260901 rated for 80 percent or 100 percent continuous current?
This breaker is standard-rated, meaning it is designed for continuous operation at 80 percent of its 90-amp capacity.
