Schneider Electric's Square D FA32050 is a 3-pole, 50-amp molded‑case circuit breaker in the FA/I‑Line family, designed to protect 240 V AC circuits inside Square D I‑Line panels. This thermal‑magnetic, plug‑in device uses a non‑interchangeable trip unit and accepts 14–1/0 AWG aluminum or copper conductors on the load side. With a 240 V AC rating and a standard interrupting capacity of 10 kA at 240 V, it serves as a feeder or branch protection device in commercial and industrial distribution systems.
