Schneider Electric FAL34050 Three Phase Circuit Breaker

Schneider Electric Square D FAL34050 is a three‑pole molded‑case circuit breaker (MCCB) in the FAL family, designed to protect three‑phase feeders in 480 V AC distribution systems. It is rated at 50 A with a 250 V DC rating for compatible DC circuits, and it uses Long‑Time and Instantaneous trip elements to provide selective, fast fault isolation across all three phases. The device features line and load side lug terminals for straightforward wiring and a compact F‑frame form factor that fits standard enclosures. Its interrupting capacity is 18 kA at 480 V, enabling safe interruption of fault currents within the device’s rating. Built for reliability in commercial and light industrial power distribution, the FAL34050 supports standard three‑phase protection in panels, switchgear, and feeders that operate at 480 VAC, with a clear, trio‑pole disconnection under fault conditions. The combination of a 50 A rating, 3P configuration, 480 VAC rating, and 18 kA interrupting capacity makes this MCCB suitable for protecting circuits against overloads and short circuits in 3‑phase networks within the same frame and voltage range.
