Schneider Electric FAL34040 Molded Case Circuit Breaker

Schneider Electric’s Square D FAL34040 Molded Case Circuit Breaker is a 40-amp, three-pole MCCB rated for 480-volt AC distribution, delivering precise overcurrent protection for three-phase feeders in industrial and commercial panelboards. As a member of the FAL family, it uses a thermal-magnetic trip mechanism and provides an 18 kA interrupting capacity at 480V, enabling reliable clearance of short circuits and fault conditions without compromising upstream equipment. The FAL34040 is configured with a feed-through termination and line-load lug arrangement, supporting convenient source-to-load wiring in a compact form factor and simplifying field installation. Suitable for 3-phase 480V systems, this breaker protects downstream circuits and equipment by monitoring current draw and tripping on overloads or short circuits, making it a common choice for distribution panels, machine tool feeds, and other industrial electrical installations that require sturdy, code-compliant protection at 40A.
