Schneider Electric FAL360401021 Circuit Breaker

Square D by Schneider Electric FAL360401021 is a 40 A, 3-pole molded case circuit breaker rated for 600 V, intended for three‑phase distribution in commercial and light industrial panels. The FAL family provides thermal‑magnetic overcurrent protection with lug terminations on both the line and load sides, enabling straightforward panel installation with standard enclosures. The device carries an interrupt rating of 14 kA at 600 VAC, with 18 kA at 480 VAC and 25 kA at 240 VAC, making it suitable for circuits where higher fault currents can occur in feeder or branch circuits. Classified in the A-frame family, this MCCB occupies a compact footprint consistent with other 40 A, 3‑pole Square D breakers in the same series. This exact model, FAL360401021, has been listed as discontinued by Schneider Electric in some catalogs, so availability can vary by region, and buyers may need to consider current substitutes in the Square D/FAL lineup.
