Schneider Electric FA36050 Molded Case Circuit Breaker

FA36050 is a 50 A, three‑pole molded‑case circuit breaker from Schneider Electric’s Square D FA family, designed for I‑Line plug‑in panelboards and providing thermal‑magnetic overcurrent protection for 3‑phase circuits up to 600 V AC. It uses a thermal‑magnetic trip mechanism and is 80% rated for continuous loads, with a load‑side lug configuration that accepts #14 to #1/0 copper or #12 to #1/0 aluminum conductors. Interrupting ratings vary by voltage: 14 kA at 600 VAC, 18 kA at 480 VAC, and 25 kA at 120/240 VAC. The FA36050 is compact for its frame and supports standard I‑Line bus connections to simplify panel installation. Typical applications include protection of 3‑phase feeders in distribution panels, motor control centers, and control circuits in light‑to‑medium industrial environments.
