Square D FAB22015AC1254 I-Line Circuit Breaker

Square D by Schneider Electric FAB22015AC is a two-pole molded-case circuit breaker designed for 240V circuits, rated at 15 A, and intended for use in Square D I-Line panelboards and equipment as a reliable overcurrent protection device in commercial and industrial electrical distributions. This thermal-magnetic MCCB provides fast, coordinated tripping for overloads and short circuits, offering an interrupt rating of 10,000 AIC at 240 V to help limit damage to conductors and downstream equipment in commercial and light-industrial distribution networks, with predictable trip characteristics. The FAB22015AC designation is commonly listed in catalogs as FA22015AC, reflecting its I-Line mounting configuration that allows plug-in installation into compatible I-Line enclosures and panels from Square D, and it is frequently preferred where space savings and standardized trip curves matter. As a compact, two-pole breaker with 240V operation, it ensures simultaneous disconnection of both hot conductors on a 240V circuit, making it suitable for protecting feeders, branch circuits, motors, and other equipment in buildings that rely on Square D I-Line systems. I-Line mounting enables plug-in compatibility with Square D I-Line panel systems, helping installers achieve a clean, reliable fit in compatible enclosures.
