The Square D BGA34015 is a 3-pole, 15A, 480Y/277V plug-in breaker from the BGA (I-Line) frame series, designed for use in Square D I-Line panelboards and switchboards — commonly used in commercial and industrial installations rather than residential loadcentres. Its 35kA interrupting rating makes it well suited for higher-fault-current environments typical of 480V commercial distribution systems.
Compatibility depends on the specific I-Line panelboard bus rating and configuration. Send us your panelboard model and we'll confirm fitment.
The BGA34015 uses Square D's I-Line plug-in mounting system, making it compatible with Square D I-Line panelboards and switchboards rated for 480Y/277V three-phase distribution. It is not designed for residential QO or Homeline loadcentres. Share your panelboard model with us and we'll confirm compatibility.
Availability can vary as Square D periodically updates or supersedes older BGA-frame catalogue numbers. Northern Breaker Group specializes in hard-to-find and obsolete breakers — contact our Calgary, Edmonton, or Vancouver counters and we'll check current stock or source it for you.
No — the BGA34015 is specifically rated for 480Y/277V (grounded wye) systems. It is not rated for ungrounded delta or 208Y/120V systems. Using a breaker outside its voltage rating is a code violation and a safety hazard; always match the breaker's voltage rating to your system configuration.
