Schneider Electric FA-24020AB Circuit Breaker

Square D by Schneider Electric FA24020AB is a 2-pole, 20 A I-Line molded‑case circuit breaker (type FA) designed for plug‑in mounting in FA frame panels and rated for up to 480 VAC in single‑phase service. It uses a thermal‑magnetic trip unit to provide reliable overcurrent protection with an interrupting rating of 25 kA at 240 VAC and 18 kA at 480 VAC. The device features a line‑side I‑Line connection and load‑side lugs for field wiring, configured for A/B phase arrangements typical of I‑Line installations, and it accepts copper or aluminum conductors on the load side. As part of the FA family, the FA24020AB is engineered for compact panel layouts and quick field replacement, making it suitable for protecting 20‑amp branch circuits in control cabinets, motor circuits, and other 480‑V, single‑phase applications where space efficiency and precise trip characteristics matter.
