Square D FA36050 Circuit Breaker

Square D by Schneider Electric FA36050 is a 50‑amp, three‑pole molded‑case circuit breaker (MCCB) engineered for industrial and commercial power distribution. Built on the FA frame, it uses an I‑Line plug‑on mounting interface for straightforward installation in compatible panels and is rated for up to 600 V AC and up to 250 V DC, with thermal‑magnetic trip protection to interrupt overloads and short circuits on three‑phase circuits. This 3P device protects feeders and equipment such as motors, pumps, and conveyors in three‑phase systems and is suitable for use in panelboards and motor control centers up to 600 VAC. Its rugged molded‑case construction and FA‑series form factor facilitate reliable protection and easy replacement in compatible Square D distributions, including panel configurations that require a dedicated 50 A 3‑pole MCCB.
