FA22100AC is a 100 A, 240 V molded‑case circuit breaker from Square D by Schneider Electric, part of the FA I‑Line family and designed for protection and switching in electrical distribution panels. This two‑pole, 240 V device uses a thermal‑magnetic trip mechanism with an interrupting rating of 10 kA at 240 V, and it features an I‑Line plug‑in line‑side connection with load‑side lugs that accept 14–1/0 AWG aluminum or copper conductors for AC operation, while being rated for an 80% continuous‑load condition. Schneider Electric lists FA22100AC as discontinued as of July 31, 2024, with a recommended replacement being the PowerPacT B family: 100 A, 2‑pole, rated for 600Y/347 VAC, 14 kA, I‑Line, thermal‑magnetic, 80% rated (part number BDA261002). The FA series mold‑style breakers are designed for plug‑in installation in compatible I‑Line panels, offering compact, reliable protection for feeders and branch circuits in commercial and light industrial settings.
