Schneider Electric FAL14040 Molded Case Circuit Breaker

Schneider Electric's Square D FAL14040 is a 1-pole, 40 A molded‑case circuit breaker rated for 480Y/277V systems. It belongs to the FAL family of molded‑case breakers and uses a thermal‑magnetic trip mechanism to provide branch‑circuit protection in commercial and industrial panels. The device is specified for 40 A and 480Y/277V (277 V line‑to‑neutral) service, making it suitable for 277/480 V three‑phase distribution environments. As a molded‑case breaker, it protects wiring and connected loads from overloads and short circuits in feeders and branch circuits, while fitting into compact panel space. Typical applications include protecting lighting feeders, small motors, and general branch circuits in commercial buildings that operate on 277/480 V power distribution.
