BGA34050 SQUARE D 3P 50A 480Y/277V 35KA I LINE

The BGA34050 uses Square D's I-Line plug-in connection system. It is designed to install in Square D I-Line panelboards and switchboards rated for 480Y/277V three-phase service — it is not compatible with residential loadcentres such as QO or Homeline panels. Contact us with your panelboard model to confirm compatibility.

The Square D BGA I-Line series can be difficult to source through standard distribution channels. Northern Breaker Group specializes in hard-to-find and obsolete breakers, so we can often locate BGA frame breakers like the BGA34050 when other suppliers cannot. Reach out to one of our counter locations or request a quote online.

The BGA34050 is rated at 35kA interrupting capacity at 480Y/277V. If your panelboard or application requires a higher AIC rating, you would need a different BGA-frame variant with the appropriate interrupt rating. Always verify that the replacement breaker meets or exceeds the AIC requirement specified on your panelboard's nameplate, and consult a licensed electrician to ensure CEC compliance.
