Square D FDA32100 Molded Case Circuit Breaker

Square D FDA32100 is a 100 A, 240 V, three-pole molded case circuit breaker designed for I-Line plug-in panels. This FDA-series MCCB delivers thermal-magnetic overload protection for 3-phase feeders with an interrupting rating of 25 kAIC at 240 V, enabling reliable short-circuit protection in commercial or light-industrial panel installations. Built with a rugged molded housing and clearly labeled trip settings, the unit fits Square D I-Line enclosures and supports standard three-phase protection of motors, pumps, lighting feeders, and other 3-phase loads. Its compact, plug-in design simplifies maintenance and replacement in existing Square D distribution systems, while the FDA32100’s 3P configuration ensures simultaneous disconnection of all phases for safe de-energization. This model is suitable for use wherever robust MCCB protection is required in 240 V, 3-phase circuits requiring a 100 A breaker.
