Product FAQs
7 answersWhich panelboards are compatible with the BGA24040Y2 circuit breaker?
This breaker features an I-Line plug-on connection, making it compatible with Square D I-Line power distribution panelboards and switchboards. It will not fit in standard NQ or NF panels.
What does the "Y2" suffix indicate in the BGA24040Y2 catalog number?
For Square D PowerPacT 2-pole I-Line breakers, the "Y2" suffix designates an AC phase connection on the panelboard bus.
Can I install this 2-pole breaker in a 3-phase I-Line panelboard?
Yes, this 2-pole breaker can be installed in a 3-phase I-Line panelboard. The "Y2" suffix ensures it will specifically connect to the A and C phases of the busbar.
How does the I-Line connection on this breaker work?
The breaker features a shrouded I-Line plug-on jaw on the line side that snaps directly onto the panelboard bus, while the load side uses standard mechanical lugs for wire termination.
What type of protection does the BGA24040Y2 provide?
This PowerPacT B-frame breaker is equipped with a thermal-magnetic trip unit, which provides reliable protection against both electrical overloads and short circuits.
Are the trip settings adjustable on the BGA24040Y2?
No, this breaker features a fixed thermal-magnetic trip unit. The overload and short-circuit trip points are factory-set and cannot be adjusted in the field.
Is the BGA24040Y2 a direct replacement for older Square D breakers?
Yes, the PowerPacT B-frame series is the designated modern replacement for legacy Square D F-frame (FA and FH) circuit breakers. It fits into the same I-Line mounting space to easily retrofit existing panelboards.
