Schneider Electric FA22020 I Line Circuit Breaker

Schneider Electric's Square D FA22020 I-Line molded‑case circuit breaker is a two‑pole, 240 V, 20 A FA frame device designed for use in I‑Line panelboards and switchboards. This thermal‑magnetic breaker provides reliable branch‑circuit protection for 240‑volt circuits and plugs into Square D I‑Line panel systems, offering a compact, plug‑in solution for distribution gear. Rated to interrupt fault currents up to 10 kA at 240 V, the FA22020AC (and related FA22020 family variants) is built for commercial and light industrial applications where fast tripping and selectivity with other FA I‑Line breakers are important. The I‑Line family uses a plug‑in mounting style and is compatible with FA frame devices on Square D I‑Line panelboards, delivering standard electrical performance with UL listing. Typical uses include protecting feeders and branch circuits in distribution panels, lighting runs, and other 240 V loads in offices, retail spaces, data centers, and light manufacturing where a 2‑pole 20 A protection device is appropriate.
