    Panel Compatibility

    The Square D BDA140501 is a BDA-frame, plug-in circuit breaker (1-pole, 50A, 480V AC, 18kA interrupting rating). The BDA frame is an industrial/commercial moulded-case series designed for use in Square D NF/NQOD panelboards and compatible industrial panelboards that accept BDA-series plug-in breakers — it is not intended for residential QO or Homeline loadcentres.

    Compatibility depends on the specific panelboard bus configuration and available space. Send us your panelboard model number and we'll confirm the fit.

    The BDA140501 is rated 1-pole, 50A, 480V AC, with an 18kA interrupting capacity. It is designed for single-phase or phase-to-neutral loads on 480V industrial or commercial distribution systems. If your system voltage or fault current rating differs, contact us and we'll help you identify the correct breaker.

    The Square D BDA frame is considered a legacy/obsolete series, and new stock can be difficult to source. Northern Breaker Group specialises in hard-to-find and obsolete breakers — request a quote and we'll check current availability from our inventory and supplier network across our Calgary, Edmonton, and Vancouver locations.

    A direct drop-in replacement must match the BDA frame's plug-in bus connection, physical dimensions, and electrical ratings. Square D does not always offer a modern cross-reference that is mechanically interchangeable with legacy BDA panelboards. We recommend sending us your panelboard model so we can verify whether a suitable replacement or exact equivalent is available.
