Built for demanding electrical systems, the Square D BGA36015 is a 15A, 3-pole molded case circuit breaker from the PowerPacT B-Frame family. It delivers reliable thermal-magnetic (LI) protection. Designed with an I-Line mounting style, this breaker installs into Square D I-Line panelboards and switchboards. It is an exact cross-reference replacement for older FA36015 models. Featuring a 35kAIC interrupt rating at 480VAC, it includes factory-installed phase ABC connections.
How does the BGA36015 mount into an electrical panel?
It features an I-Line plug-on design. The breaker ratchets firmly onto the panel bus stack and is secured in place by a built-in mounting bracket, eliminating the need to manually bolt on busbar connectors.
Is the BGA36015 a direct replacement for older 15A FA-frame breakers?
Yes. The PowerPacT B-Frame serves as an exact replacement for older Square D FA36015 I-Line circuit breakers, allowing you to upgrade existing switchboards without modifying the bus structure.
What does the letter G signify in the BGA36015 catalog number?
In Square D PowerPacT nomenclature, the G indicates the breaker's interrupting capacity tier. For this B-Frame model, it designates a 35kA short-circuit current rating at 480VAC.
What type of wiring is compatible with the factory lugs?
The factory-installed lugs accept both copper and aluminum wire. Supported conductor sizes range from 14 AWG up to 2/0 AWG, making it versatile for various field installations.
Can this breaker be used in DC power circuits?
Yes. In addition to typical AC applications, this model is rated for 250VDC systems with a maximum interrupting capacity of 20kA.
Will this breaker fit into standard Square D QO load centers?
No. The I-Line mounting style is exclusively compatible with industrial Square D I-Line panelboards and switchboards. It cannot be installed into residential QO or Homeline enclosures.
Does this 3-pole breaker include phase connection hardware?
Yes. It comes with factory-configured ABC phase connections that are designed to align and engage seamlessly with the corresponding busbars in a 3-phase I-Line panel.
Are the trip settings adjustable on this PowerPacT breaker?
No. This specific model features a fixed thermal and fixed magnetic trip unit. Neither the continuous current overload nor the instantaneous short-circuit pickup levels can be altered in the field.
