    Panel Compatibility

    The Square D BDA140303 is a 1-pole, 30A, 480V, 18kA plug-in molded-case circuit breaker from the BDA (I-Line) frame series. As an I-Line (Phase B) plug-in breaker, it is designed to mount in Square D I-Line panelboards and switchboards — not in residential QO or Homeline loadcentres. It is suited to industrial and commercial distribution applications where 480V system voltage and a robust 18kA interrupting rating are required.

    Panel and switchboard compatibility depends on your specific I-Line enclosure configuration. Send us your panelboard model and we'll confirm fit before you order.
