The Square D BDA140151 is a plug-in, single-pole 15A 480V breaker from the BDA (I-Line) frame series, designed for use in Square D I-Line panelboards and switchboards — commercial and industrial distribution equipment. It is not a residential QO or Homeline breaker and is not suitable for loadcentres. With an 18kA interrupting rating at 480V, it is well-suited for branch-circuit protection in commercial and light industrial panels.
Panel fit depends on your specific I-Line panelboard model and bus configuration. Send us your panelboard model and we'll confirm compatibility.
The BDA140151 belongs to Square D's I-Line breaker family and is designed to plug into Square D I-Line panelboards and switchboards used in commercial and industrial applications. It is not interchangeable with Square D QO or Homeline residential loadcentres. Share your panelboard model with us and we'll confirm the exact fit.
The BDA I-Line series has largely been superseded by newer Square D breaker lines. The BDA140151 may be difficult to source through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — contact us for current availability and lead times.
Yes — a breaker rated for 480V AC can generally be applied at lower voltages within its current and interrupting rating. However, always verify with your engineer or authority having jurisdiction (AHJ) that the breaker's full specifications meet the requirements of your specific panelboard and circuit application before installation.
