BDA34060 SQUARE D 3P 60A 480Y/277V 18KA I LINE
The BDA34060 SQUARE D circuit breaker is a robust 3-pole, 60A unit designed for 480Y/277V applications. With an impressive interrupting capacity of 18kA, it ensures reliable protection for your electrical system. Ideal for commercial and industrial use, this breaker guarantees safety and efficiency in your operations.
The BDA34060 uses Square D's I-Line plug-in mounting system, making it compatible with Square D I-Line panelboards and switchboards designed for 480Y/277V, 3-phase distribution. It is a commercial/industrial breaker and will not fit residential QO or Homeline loadcentres. Share your panelboard model with us and we'll verify compatibility.
The BDA frame has been largely superseded by newer Square D MCCB lines, making the BDA34060 a hard-to-find unit. Northern Breaker Group specializes in obsolete and discontinued breakers — we maintain stock of legacy Square D breakers and can often source units that are no longer available through standard distribution channels. Contact us for current availability.
The BDA34060 is rated for 480Y/277V, 3-phase systems. While using a higher-rated breaker on a lower-voltage system is generally permissible from a voltage standpoint, the interrupting rating (18kA) and suitability must still be verified against the available fault current at your specific installation. Always consult a licensed electrician and confirm with your authority having jurisdiction (AHJ) before substituting breakers in any panel.
