Product FAQs
6 answersWhat panels are compatible with the BGA34090Y?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It is not compatible with standard unit-mount enclosures or load centers.
Can the BGA34090Y replace older Square D circuit breakers?
Yes, the PowerPacT B-Frame BGA34090Y serves as a modern, direct replacement for the legacy F-Frame FA34090 circuit breaker. It is designed to fit the same I-Line applications to simplify retrofitting.
How is the BGA34090Y installed into the panel?
It uses an I-Line plug-in connection that engages directly with the panelboard busbar for the line side, while the load side utilizes the factory-installed lugs.
What are the wiring requirements for the standard lugs?
The load-side lugs accept either aluminum or copper conductors, accommodating wire sizes from 14 AWG to 2/0 AWG.
What does the LI trip function indicate on this breaker?
The LI designation means the thermal-magnetic trip unit provides Long-Time (L) and Instantaneous (I) protection. Both the thermal and magnetic trip settings are fixed on this model.
Is this breaker suitable for DC voltage applications?
Yes, in addition to its standard AC ratings, the BGA34090Y is rated for use in DC circuits up to 250VDC with an interrupting capacity of 20kA.
