Square D FCL340151212 Three Phase Circuit Breaker

Square D by Schneider Electric FAL340151212 Molded Case Circuit Breaker is a three-pole, 15-amp unit designed for three-phase protection in industrial panels. The F-frame molded-case design uses a thermal-magnetic trip to provide fast overcurrent protection for loads drawn from 480 VAC systems. It carries an 18 kAIC interrupt rating at 480 VAC (25 kAIC at 240 VAC), making it suitable for motors, pumps, and other demanding equipment in commercial and light industrial environments. Line terminals use I-Line, while the load side accepts lug connections, aligning with common Square D panel configurations. The device measures roughly 6.2 inches in height, 6.2 inches in width, and 9.8 inches in length, and is UL Listed for use in compatible Square D enclosures. This model—catalog number FAL340151212; some catalogs list it under the variant designation FCL340151212—belongs to Square D’s molded-case breaker lineup, offering robust, field-replaceable protection in a compact form factor for 3-phase distribution at 480 VAC. Typical applications include safeguarding 3-phase motors, compressors, and other 480-V loads in manufacturing and building automation systems where reliable trip performance and coordination with nearby protective devices are important.
