    The Square D BDA140703 is a BDA-frame, 1-pole, 70A, 480V plug-in circuit breaker with an 18kA interrupting rating. The BDA frame is a commercial and industrial-grade molded-case breaker designed for use in Square D NQ, NF, and I-Line panelboards and compatible switchboards — it is not intended for residential QO or Homeline loadcentres.

    Exact fitment depends on your panelboard's bus configuration and available space. Send us your panelboard model number and we'll confirm compatibility.

    The BDA-frame plug-in breaker is designed for Square D commercial and industrial panelboards such as the NQ and NF series I-Line panels. It is not suitable for residential QO or Homeline loadcentres. Contact us with your panelboard model and we'll verify the fit.

    The BDA series is a legacy Square D frame. Availability can be limited, and Northern Breaker Group specializes in sourcing hard-to-find and obsolete breakers just like this one. Reach out for a quote — we maintain stock of discontinued Square D commercial breakers across our Calgary, Edmonton, and Vancouver locations.

    The BDA140703 is rated for 480V, which means it is also suitable for use on lower-voltage systems (e.g., 120/240V or 208V), as the voltage rating represents the maximum. However, always verify with your panelboard specifications and ensure the breaker's ampere and interrupting ratings meet your system's requirements before installation.
