The BDA34015 SQUARE D 3P 15A 480Y/277V circuit breaker is designed for reliable protection in electrical systems. This three-phase circuit breaker features an 18KA interrupting capacity, ensuring robust safety. Ideal for use in commercial and industrial applications, it delivers exceptional performance and durability, making it a valuable addition to your electrical supply.
The BDA34015 uses Square D's I-Line plug-in mounting system, so it is designed for Square D I-Line panelboards and switchboards rated for 480Y/277V commercial and industrial distribution. It is not compatible with residential QO or Homeline loadcentres. If you're unsure whether your panelboard accepts I-Line plug-in breakers, share the panel model with us and we'll verify the fit.
Square D BDA-frame I-Line breakers can be difficult to source as the product line matures. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so we maintain inventory of legacy Square D I-Line units. Contact one of our counters in Calgary, Edmonton, or Vancouver, or request a quote online, and we'll check current availability for you.
The BDA34015 is rated for 480Y/277V systems. While a breaker rated for a higher voltage can generally be applied on a lower-voltage system of the same type (consult the Square D documentation and a licensed electrician to confirm), you must also ensure the panelboard buswork, mounting style, and AIC rating all meet the requirements of your specific installation. Always verify with a qualified electrician and your local authority having jurisdiction (AHJ) before substituting voltage ratings.
