Product FAQs
6 answersWhich panelboards accept the BGA24100Y1?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It will not fit standard QO, Homeline, NQ, or NF panels.
Can the BGA24100Y1 replace an older FA series breaker?
Yes, this PowerPacT B-Frame breaker serves as a direct replacement for the legacy Square D FA24100AB molded case circuit breaker in I-Line panelboards.
What does the Y1 suffix indicate on this breaker?
The Y1 suffix specifies an AB phase connection. The breaker jaws are configured to connect exclusively to the A and B phases on the I-Line bus.
How does the I-Line connection work on the BGA24100Y1?
The breaker features a plug-on jaw assembly on the line side that clips directly onto the I-Line bus. The load side utilizes standard mechanical lugs for wire termination.
How do you decode the BGA24100Y1 catalog number?
B denotes the PowerPacT B-Frame. G indicates the interrupting rating tier. A specifies the I-Line mounting style. 2 is for 2 poles, 4 indicates a 480VAC maximum rating, 100 is the amperage, and Y1 specifies an AB phase connection.
Does the BGA24100Y1 feature current-limiting contacts?
Yes, PowerPacT B-Frame breakers utilize dual-break rotating contacts that reduce peak let-through current during a short circuit fault.
