    Panel Compatibility

    The Square D BDA140301 is a 1-pole, 30A, 480V plug-in molded-case circuit breaker from the BDA (I-Line) frame series, rated at 18kA interrupting capacity. The BDA I-Line frame is designed for use in Square D I-Line panelboards and switchboards — it is not a residential loadcentre breaker. It is suitable for commercial and industrial 480V distribution applications where a plug-in I-Line mounting is specified.

    Compatibility depends on your specific panelboard's bus configuration and frame size. Send us your panelboard model and we'll confirm the fit.

    The BDA140301 uses Square D's I-Line plug-in mounting system, which is designed for Square D I-Line panelboards and switchboards used in commercial and industrial installations. It is not compatible with residential QO or Homeline loadcentres. Contact us with your panelboard model to confirm compatibility.

    The BDA140301 is a single-pole (1P) breaker rated at 480V, making it suitable for protecting individual branch circuits in 480V systems — typically within a three-phase 480V distribution panelboard. It is not a multi-pole breaker and protects one ungrounded conductor at a time.
