What does the Y4 suffix mean in the BGA24015Y4 catalog number?
The Y4 suffix indicates that this 2-pole breaker is configured with a BC phase connection. It is specifically designed to connect to the B and C phases of an I-Line panelboard busbar.
Can the BGA24015Y4 be used to replace older Square D FA series breakers?
Yes, the PowerPacT B-frame is the modern replacement for legacy Square D F-frame breakers. The BGA24015Y4 serves as a direct drop-in replacement for the discontinued FA24015BC, matching the 15 Amp rating, 2-pole configuration, and BC phase connection.
What does the "G" in the BGA24015Y4 catalog number indicate?
In the Square D PowerPacT B-frame series, the "G" designates the interrupting rating tier. This specific tier provides a breaking capacity of 35 kA at 480Y/277 VAC and 65 kA at 240 VAC for commercial and industrial applications.
How does the I-Line mounting system work on the BGA24015Y4?
The I-Line mounting system uses a shrouded plug-on jaw that snaps directly onto the panelboard busbar. This allows for fast, secure installation without the need for additional mounting hardware or wire connections on the line side.
