Product FAQs
6 answersWhich panelboards are compatible with the BGA36125 circuit breaker?
This B-Frame breaker is designed exclusively for Square D I-Line panelboards and switchboards. It uses a plug-on line connection that mounts directly to the I-Line busbar stack.
Does the PowerPacT BGA36125 replace older Square D I-Line breakers?
Yes, the PowerPacT B-Frame series is the designated replacement for legacy Square D F-Frame circuit breakers, specifically the FA and FH I-Line series. It maintains the exact same mounting space dimensions to allow for seamless retrofitting in existing panelboards.
What does the "G" indicate in the BGA36125 catalog number?
The "G" designates the interrupting capacity tier for the PowerPacT B-Frame series. For this specific model, it provides a maximum interrupting rating of 65kA at 240VAC and 35kA at 480VAC.
How is the BGA36125 circuit breaker mounted and wired?
It uses a shrouded I-Line style plug-in jaw for the line side, which snaps securely onto the panelboard bus. The load side utilizes standard mechanical lugs for the outgoing wire connections.
What type of protection does the trip unit on this breaker provide?
It is equipped with a fixed thermal magnetic trip unit, denoted by the LI code. The thermal element provides Long-Time (L) protection against overloads, while the magnetic element offers Instantaneous (I) protection against short circuits.
What wire sizes are compatible with the load lugs on the BGA36125?
The factory-installed mechanical lugs on the load side will accept either copper or aluminum conductors ranging from 14 AWG to 2/0 AWG.
