Square D by Schneider Electric FAL220401127J Circuit Breaker

The Square D by Schneider Electric FAL220401127J is a 2-pole circuit breaker rated for 40 A at 240 V, designed to provide overcurrent protection for 240 V circuits in electrical panels and equipment. Belonging to Square D's FA/FAL legacy family, the device is described in product listings as a thermal-magnetic circuit breaker used to interrupt overloads and short circuits in 240 V circuits. The trailing 'J' suffix designates Japan as the shipping region; these suffix units ship with their contacts closed to prevent oxidation during overseas transport to Japan, and such suffixes are not offered for domestic shipments. As a Square D product, it is part of the brand's broad portfolio of protectors for electrical installations, and its 240 V, 40 A, 2-pole specification aligns with other FA/FAL models that serve 240 V branch circuits in compatible panels.
