Square D FA24020AC I Line 2 Pole Circuit Breaker

Square D FA24020AC is a 2-pole I-Line molded‑case circuit breaker from Schneider Electric’s FA family, designed for 480 V AC, single‑phase service. This plug‑in FA‑series device uses I‑Line mounting to install into FA panelboards and is rated at 20 A with an 18 kA short‑circuit rating at 480 V (AIC), providing robust protection for feeder or branch circuits in industrial environments. The unit is a 2P, 1PH breaker, suitable for protecting 480 V loads such as motors, control circuits, and other single‑phase equipment, while offering thermal‑magnetic protection that trips on overcurrent or short circuit events. Its compact MCCB construction and I‑Line style plug‑in mounting streamline panelboard integration and serviceability, and it is designed to operate under ambient conditions up to 40°C. In Square D’s FA/I‑Line ecosystem, FA24020AC complements other FA‑series breakers to deliver coordinated protection and easy replacement within commercial and light industrial distribution systems that rely on reliable 480 V single‑phase protection up to 20 A.
