Square D FA24020AC 2-Pole 20A 480V Circuit Breaker

FA24020AC is a 20A, 2-pole molded‑case circuit breaker from Square D’s FA I‑Line family, designed for 480 VAC service and intended for FA‑series I‑Line plug‑in panels. It provides thermal‑magnetic protection for two‑pole circuits, with line‑side I‑Line connections and load‑side lugs compatible with 14‑4 AWG aluminum or copper conductors. The unit carries an 18 kA short‑circuit interrupting rating at 480 VAC (25 kA at lower voltages such as 240 VAC, per model data), and is rated for 80% continuous load. This breaker is typically used to protect feeders or control circuits in industrial or commercial distribution systems where compact, serviceable protection is required in 480 VAC environments.
