Square D FA22100BC I-Line Circuit Breaker

Square D FA22100BC is a 2‑pole molded‑case circuit breaker designed for I‑Line panelboards, rated for 240V AC and 100A. It provides thermal‑magnetic overcurrent protection for two conductors in industrial and commercial distribution systems, with a 10 kA interrupting rating at 240V to reliably clear faults on typical feeders. As part of Schneider Electric’s FA family, this I‑Line plug‑in breaker is intended for use in compatible Square D panels and features a molded housing with a thermal‑magnetic trip mechanism to protect circuits from overloads and short circuits. The FA22100BC is deployed as a branch or feeder breaker within suitable FA‑series I‑Line panelboards and can be coordinated with other FA breakers to maintain a consistent protection scheme across installations. Built for standard 240V systems, it underscores Square D’s lineage in industrial distribution gear and provides a robust, field‑installable solution for two‑pole protection in commercial or light industrial applications.
