Square D FAL34100 Feed-Through Circuit Breaker

Square D by Schneider Electric FAL34100 is a 3-pole molded-case circuit breaker (MCCB) from the FAL feed-through family, rated at 100 A with line and load lug terminals for straightforward feed-through installation. This 3-phase device is compatible with up to 480 VAC (line-to-line) and carries a 250 VDC rating, with UL/CSA/NOM listings for multiple regional standards. The FAL34100 employs a thermal-magnetic trip system (long-time and instantaneous) and provides a short-circuit interrupting rating up to 18 kA at 480 VAC, making it suitable for feeder applications in industrial panels. As a feed-through breaker, it is intended to power downstream sub-panels from a main distribution point while maintaining robust protection across the distribution network. Part of the Square D FAL family and built with F-frame construction, this MCCB is designed for demanding power distribution environments where reliable, code-compliant protection is required.
