Product FAQs
7 answersWhich legacy Square D breakers does the BGA140203 replace?
The PowerPacT B-frame series is the direct replacement for legacy Square D FA and FH series breakers, such as the FHB16020B. It maintains the same 1.5-inch I-Line mounting footprint for easy retrofitting.
What does the "3" at the end of the BGA140203 catalog number indicate?

The "G" designates the interrupting rating tier. For the B-frame series, the G-rating provides 65 kAIC at 240V and 35 kAIC at 480Y/277V.
How much mounting space does this 1-pole breaker require?
