The FA24020AB from Square D by Schneider Electric is a 20-amp, 2-pole molded‑case circuit breaker (I‑Line type) designed for 480 V AC systems and up to 250 V DC ratings. It features line-side I‑Line connections with AB phase configuration and load-side lug terminations, and accepts 14–4 AWG aluminum or copper conductors. With a thermal-magnetic trip, it is rated for 80% continuous duty and delivers an interrupting rating of 18 kA at 480 V (25 kA at 240 V), making it suitable for protection of 480 V circuits in commercial or industrial panelboards that use Square D I‑Line MCCBs.
