Square D By Schneider Electric FA34015G Circuit Breaker

Square D by Schneider Electric FA34015G is a gray-label, three-pole molded-case circuit breaker (MCCB) in the FA frame, built for 480 V AC service with a nominal 15 A rating and three conductors to protect three-phase loads. It uses thermal-magnetic trip technology and carries an interrupting capacity of 14 kA at 600Y/347V (UL), enabling fast isolation of faults in industrial distribution panels while meeting common protection requirements for 3-phase circuits. Schneider Electric lists FA34015G as discontinued as of June 30, 2023, with the PowerPact B family replacement, such as the BDL36015, offering a like 15 A, 3-pole device rated for 600Y/347 VAC and similar 14 kA interrupting capability. Wiring and termination on FA-series devices accommodate copper conductors from 14 to 4 AWG and aluminum from 12 to 4 AWG, and the gray-label variant is often associated with legacy installations and FA/I-Line bus configurations where these breakers were originally deployed.
