Schneider Electric FA32100 I-Line Circuit Breaker

Schneider Electric's Square D FA32100 I-Line molded‑case circuit breaker is a 100 A, 3-pole unit rated for 240 V AC, designed for FA‑frame installations with I‑Line busway compatibility. This thermal‑magnetic breaker delivers reliable overload and short‑circuit protection in three‑phase distribution panels and is part of the FA family, built to protect 240 V three‑phase circuits in commercial and light‑industrial power systems. The FA32100 is commonly used for main feeder or branch protection of motors, transformers, MCCs, and other three‑phase loads within its 100 A circuit capacity, leveraging I‑Line construction for streamlined integration with compatible Schneider Electric panelboards and busways. Inline with Square D’s FA/I‑Line protection lineup, this 3P device provides the solid, field‑installable protection required in distributed power applications that rely on 240 V three‑phase service.
