Schneider Electric FA24020AC I Line Circuit Breaker

Schneider Electric FA24020AC is a 2‑pole, 20‑A molded‑case circuit breaker from the Square D I‑Line FA family, designed for 480 V AC single‑phase service in compatible I‑Line panelboards. It uses an I‑Line plug‑in mounting style and is configured for phase option AC (A–C) connections on the line side, with load side Lugs for conductor termination. The device provides thermal‑magnetic overcurrent protection with a listed interrupting rating of 18 kA at 480 V, suitable for protecting branch circuits in industrial or commercial 480 V applications. Terminal connections support aluminum or copper conductors in the range typically specified for FA I‑Line devices, with a line‑side range often cited as 14–4 AWG Al/Cu. The FA24020AC is part of Schneider Electric's FA I‑Line series, designed for use in compatible Square D panelboards and enclosures for reliable protection and straightforward replacement.
